  1. Is msp430fr5994 launchpad supported by any realese of energia ? I searched in boards section and couldn't find. Is there any patches to make it work ? Or it's not supported ?
  2. An output power display for my solar system. G2553 Launchpad, Blue 4-digit LED display, RS485 Transceiver SN65HVD12P (a low power, 3.3V version of the standard SN75176), this is all there is. All pins are used, 4 + 7 for the multiplexed LEDs (no resistors: Blue LED, 3.6V supply, output resistance of the pins limit the LED current) 3 pins for UART and send/receive for the SN65. 2 pins for 32768Hz xtal (I had this one soldered in on the LP, so why not use it) The MSP asks the inverter over RS485/Modbus "what is your current output power". After less than half a sec, the inverter aswers with the required value. This repeats every 2 seconds. The inverter is a Fronius Symo, with Datamanager 2 (which I guess is an embedded linux machine, covering LAN, Wifi, Modbus.....). The communication protocol can be downloaded from the Fronius website (after signing in), so no reverse engineering was required. Instead of only power, I could also display line voltage, frequency, total delivered energy.... This is just a working prototype on Launchpad, I will do a PCB later, I also plan to power this directly from the inverter (which has a 12V solar powered output for such things). See the picture, almost 7.5kW :-)
  3. I designed a board using a MSP430G2553IPW28R its the 28 pin tssop package. I read on this forum that you can use the launchpad to program the part I have some code written and can program a 20 pin device but when i connect the wires to my board from the launchpad is cant find the device or its not there. Error connecting to the target: Could not find device (or device not supported) I used CCS and just for the hell of it did the MSP-EXP430G2-LaunchPad User Experience Application example which programs just fine but i get the same error when plugged onto my board. Here is how i connected the part to the launchpad. Yes 20 pin IC removed from launchpad. I am at a loss. My board is powered from its own 3.3v supply and the grounds are common. The ground is always connected between the launchpad and the proto board. for testing i just remove/reconnect the 2 spy-by-wire pins and add/remove the 20 pin g2553 for testing the output. The 28 pin parts are new from mouser and i have 2 boards that i built that do the same thing. Any help would be nice
  4. My compact Lisp interpreter, uLisp, now supports the MSP430F5529 and MSP430FR5969 LaunchPads. As well as supporting a core set of Lisp functions, uLisp includes Arduino/Energia extensions, making it ideal as a control language for the MSP430. For more information see
  5. Hello Forums I am trying to use GUI Composer v2 (on the cloud) to create a GUI for a battery managment system, similar to the one in the SLAA478 Application Report, using the MSP-EXP430F5529LP and bq76PL536EVM-3. I've decided to use USB/Serial comms, which requires me to modify the code to send the information using JSON. I am following the example of using USB/Serial IO: The code given is as follows: #include <aJSON.h> // most launchpads have a red LED #define LED RED_LED //see pins_energia.h for more LED definitions void printled_statewithjson(int state){ aJsonObject* root = aJson.createObject(); if (root == NULL) { return; } aJson.addItemToObject(root, "LED", aJson.createItem(state)); char* string = aJson.print(root); if (string != NULL) { Serial.println(string); free(string); } aJson.deleteItem(root); } // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(LED, OUTPUT); Serial.begin(9600); } // the loop routine runs over and over again forever: void loop() { digitalWrite(LED, HIGH); // turn the LED on (HIGH is the voltage level) printled_statewithjson(1); // print json object with LED status set to 1 to UART delay(1000); // wait for a second digitalWrite(LED, LOW); // turn the LED off by making the voltage LOW printled_statewithjson(0); // print json object with LED status set to 0 to UART delay(1000); // wait for a second } I am trying to fully understand this example code, before implementing it into my program. Using CCS Cloud, I stepped through the program in debug mode. From what I understand, the loop() function is essentially the main function, which blinks the LED; setup() does as expected and initializes the MCU LED pin, and opening a serial port at 9600 baud rate. I cannot, however, understand the printled_statewithjson() function. How exactly does it work to be able to send the information? Regards
  6. Hi All, I am working on a project using the CC1310 LaunchPad, and it will be powered directly from a 3V (nominally) battery. I want to use the ADC to accurately read the voltage from one of my sensors, and the problem that I am having is that the reference seems to be relating to the voltage the LaunchPad is running from. I have tried using analogReference(), but it wont compile with the parameter INTERNAL1V5, and when i try INTERNAL2V5 it does compile, but it still seems to be using the battery voltage as the ADC reference. Please can someone explain how I can get a stable voltage reading on the ADC despite the variation in the battery voltage? I am also designing a custom PCB for this project, based on the LaunchPad reference design, if that helps? Additionally, it would be very helpful to monitor the battery level. Can the cc1310 do this, or will I need to connect the battery to an ADC input pin? Regards, -Steve
  7. The CC1310 board option in Energia assumes that I am using the CC1310 Launchpad. The launchpad uses the CC1310F128RGZ, but I actually am using the CC1310F64RHBT. This means that the board is assuming it has more flash and RAM than it actually does. I want to edit the boards.txt file to match with the specs of my chip but I cannot find the correct numbers for my chip. There is also an issue with the pin mapping, because the F128RGZ has 48 pins while the F64RHBT has 32. Here the boards.txt for the CC1310 launchpad that needs to be adapted for the CC1310F64RHBT: menu.cpu=Processor LAUNCHXL_CC1310.vid.0=0x2341 w/ cc13xx EMT (48MHz) LAUNCHXL_CC1310.upload.maximum_size=16384 LAUNCHXL_CC1310.upload.maximum_ram_size=2560 LAUNCHXL_CC1310.upload.tool=dslite LAUNCHXL_CC1310.upload.protocol=dslite LAUNCHXL_CC1310.upload.maximum_size=131072 LAUNCHXL_CC1310.upload.maximum_data_size=8192 If anyone could help me adapt my boards.txt file or let me know where I can get these numbers, let me know. I have tried inputting 64kb for flash and the other appropriate values, but it didn't work because I assume the values have to line up perfectly with the chip's memory sectors and the memory map. Thanks, Cameron
  8. I started learning TIVA C launchPad from past 15 days only . I am watching youtube videos. and refering datasheet. I wrote code in DRM style ,ie. direct register assignment method as shown in videos. I know little only about ADC , timer as I used these modules only. I want to learn API style coding using tivaware. How do I start..? there are many doc and videos that talks about how to install tivaware, CCS or IAR workbench. there is pdf by TI -> ' TivaWare
  9. Hi, I am currently working on a code in Energia that will allow me to upload and send a binary file wirelessly from a client site to the CC3200. So far, the code has successfully accomplished the following: -the board establishes a Wi-Fi network -commands from a laptop can interact with the board (the Energia Simple Wi-Fi Server example (LED ON/OFF) code was tested to ensure this was working) -a 9 byte binary file is sent through Wi-Fi to the board's volatile memory, saved from volatile memory into an on-baord flash memory file, and confirmed by sending it back to the laptop through a serial connection The code is eventually supposed to receive a larger binary file (we hope around 500 KB) that will represent points on a sinusoidal curve. This file will then be sent to the Audio Booster Pack board to play the audio file. I created a flash file which was opened, and written to through a buffer array containing the binary file contents. This method was successful for a 9 byte file, but I learned that a larger 500 KB file cannot be stored in a buffer array so easily. I think this is because of a lack of RAM space on the board. How can I implement a code in Energia in order save this larger binary file to the flash memory? Is the buffer array approach a good method? Latency isn't really an issue, as long as we can fit the whole file on the board, and then play it after. Thanks, any support is greatly appreciated!
  10. Good morning, I'm using the latest Energia 18 build with Windows 10. I'm plugged into an MSP430 Launchpad with an MSP430G2553 chip on the board. The following code hangs on the Wire.endTransmission() statement.. Can somebody throw me a bone here and tell me how to fix this? int findAddress(int fromAddress, int toAddress) { int address = 0; for (int a = fromAddress; a < toAddress; a++) { Serial.print(a); Serial.print(" - beginTransmission.. "); Wire.beginTransmission(a); // delay(3); // Wire.write(1); Serial.print(" endTransmission.. "); int endStatus = Wire.endTransmission(); Serial.print(" Result: "); if (endStatus == 0) { address = a; Serial.print("Found device at: "); Serial.println(address); } else { Serial.print("x"); } } return address; }
  11. This code example works with Anaren and CC2500 BoosterPacks, (and of course with many other CCxxxx boards, like eZ430-RF2500,) and with G2553 LaunchPad. The code was based on slaa325 from TI (I am using same RF configs.) To use it, just un-comment one of the following lines in msp.h: //#define HARDWARE 2500 // CC2500 BoosterPack SPI1 G2553 LP //#define HARDWARE 915 // Anaren (915MHz) G2553 LP //#define HARDWARE 4302500 // EZ430-RF2500
  12. Is there a way to use the SoftwareSerial library on the Stellaris Launchpad TM4C123GXL board? I am trying to connect a Sparkfun serial enabled LCD screen to the board but the SoftwareSerial library is only compatible with 20, 16, and 8 MHz processors, and the TM4C123GXL is an 80 MHz chip. How can I use this LCD screen with the Stellaris Launchpad over a UART connection? Do I need to use SoftwareSerial or can I do without it? I am programming in Energia 0101E0017 on Windows 7 64 bit. Any help is greatly appreciated, thanks!
  13. Hi, TI has a new launchpad MSP430FR5994 LaunchPad Development Kit based on the MSP430FR5994. The new controller is in "Preview" status , but looks interesting -- 256KB FRAM + 8KB RAM + a Low-Energy Accelerator for Vector Math Operations ( TI claims 35x Faster Than ARM Cortex-M0+ Core for 256-Point Complex FFT ). Check the app note Benchmarking the Signal Processing Capabilities of the Low-Energy Accelerator (Rev. A) for details. The launchpad itself is interesting as it has an on-board micro SD card and super capacitor. Has any one got hands on experience with this one? I was thinking of getting one for a data-logging application, 256KB FRAM + SD card combo is very much tempting. Would like to hear from you guys , has TI finally going in the right direction, as far as MSP430 is concerned, with the LEA in the fight against ARM?
  14. I was trying to get the Tiva Launchpad TM4C123 working with the Nokia 5110 using Energia. Eventually I came across this page: You can follow the series of questions and answers through which Clarence Ho helped me get the combination working. You can see that he used a library originally by Rei Vilo, modified to add a contrast command. You can see also that Clarence has now added the jump-wire connections which are needed to link the Launchpad and LCD, near the top of the page. I then investigated graphics, and added Graphics commands to Rei Vilo's library - some were adapted from libraries designed to interface the 5110 to Arduinos. (I've quoted all sources in the file itself) You can see the result on this Youtube page: As you can see, also included is a simple Pacman-style game using the Graphics commands. You may want to jump over the part showing Pacman game, if you want to try it yourself first. I've also now added another Pacman-style game - but generated randomly. There's a choice of ten sets of games (A-J), each with a potentially infinite number of levels. Note that although the games are generated randomly, the starting point for the random number generator used in each set of games is the same. So, GamesA for instance always has exactly the same levels. The Library and games can be downloaded from: ... and of course, the Energia code is easy to edit, so you can adapt the programmes for your own needs. I hope they are of some use to those who arrive at this page looking for help with connecting the Nokia 5110 to the Tiva Launchpad TM4C123.
  15. There is a new series of YouTube postings that uses Texas Instruments parts and microcontrollers by Peter Oakes. I have started watching it and have found it interesting. It seems pitched at the hobbyist level (pretty basic at times), but goes beyond just a recipe to make something work and he even pulls out the datasheet!: EDIT: I have watched a few more of these and apparently they are TI sponsored.
  16. So I'm working on a fingerprint scanner project with this repo written for arduino for the scanner I'm using. I am trying to make it work with an MSP430G2553 instead of the Arduino Uno. When I try using this library in Energia, it can't find the scanner despite being wired on the launchpad the same way that it is wired on the Arduino (External 5V source, Arduino pin 2 --> MSP430 pin 1.1, Arduino pin 3 --> MSP430 pin 1.2). The code compiles and the serial monitor outputs the test looking for the scanner, but it has yet to be able to find it. If anyone could give me any help with this, it would be greatly appreciated. Energia ino sketch is attached. EDIT: So after making myself more familiar with the code and the C++ imports, it seems the scanner works in 4 phases: 1) Take image 2) If image is a finger, convert it to digital features 3) Compare fingerprint features against features of enrolled fingerprints 4) Able to return result for the comparison and if its a match, return the ID# These lines: SoftwareSerial mySerial(5, 6); //Define serial communication on two pins Adafruit_Fingerprint finger = Adafruit_fingerprint(&mySerial); Seem to be whats handling all the fingerprint logic. So the issue isn't with the scanner, its with the communication between scanner and the MSP, most likely that I'm somehow defining output pins 5 and 6 (P1_3 and P1_4) incorrectly so they are not handling the scanner at all. fingerprint.ino
  17. So I'm working on a fingerprint scanner project with this repo written for arduino for the scanner I'm using. When I try using this library in Energia, it's been giving me a ram error and refuses to compile. I know that pin assignments and certain things are different between using Arduino to program an atmega microprocessor and using Energia to program an MSP430G2452 with a launchpad, but just compiling it without uploading shouldn't change anything. Here are the errors I'm getting when I try to compile the enroll sketch (attached below) -enroll.cpp.elf section `.bss' will not fit in region `ram' -`ram' overflowed by 50 bytes I've already had to fix a bunch of errors and file imports switching this over to Energia, but now I've hit a brick wall and I have no idea how to fix a problem like this. If anyone could help me with this, I would greatly appreciate it!!! enroll.ino
  18. Ti dropped a new launchpad today, it isn't even listed on the page. From the email: "the world
  19. Does anyone have the test firmware for the original Educational BoosterPack as shown on the YouTube video: It would be very helpful to me to see the code for this testing script. Thank you for any help with this.
  20. Good morning everybody, I'm Curtis, Fairly new to the world of MSP430, but VERY HAPPY that this forum exists. Energia has made my life much easier. I was about to make a hole in my wall by repeatedly bashing my head against it, but Energia removed a bunch of the minutia and provides a great abstraction layer and way of programming the MSP4230G2553 controller. See ya 'round, Curtis

  22. Hello! I am using Energia to program TM4C123GXL board. The program performs a primitive data acquisition with low frequency and stores it (together with timestamps) as an array in RAM. I would like to store data in EEPROM or, preferebly in FLASH. Micro-controller has 256kB flash. How can I save data there? There is flash API (flash.h and flash.c) in lm4f/driverlib/ though I am not sure even at which address range I can write/erase data? Can anybody point out to a working example? thanks for help!

LED jumpers control which LEDs are used, on board or socket. Available on Tindie.
  24. Hi folks, sorry that I have so many questions in the moment, but I do not find to many other sources for help. I got a bunch of G2252IN20 for under 50cents a piece. Because of the pinout, that is quiet similar to the G2452 I thought I can program it with my launchpad. But when I put the chip into the launchpad, start mspdebug and try to download my code, I get the following error: Writing 818 bytes to 0xc000 fet: FET returned error code 7 (Could not write device memory) fet: failed to write to 0xc000 On an Energia site I found that this happens when you have choosen the wrong target, but I do not use Energia. Even when I start mspdebug this way: mspdebug rf2500 --fet-force-id MSP430G2252 I get the same error. Has anybody any idea what I do wrong? Greetings Sven
  25. I am uploading the fade example of energia to the tiva t4mc1294 connected launchpad but the LED is not fading. It is just blinking. I have also connected the pwm output to motor drivers but the speed of the motors are not changing. When I check the voltage of the pin with my multimeter, I get 0.66v. I have tried the fade example on different pins like PF2, PF3(pins marked for analogWrite in launchpad reference) but the results are same. Here is the code for the fade example, given as reference. int brightness = 0; // how bright the LED is int fadeAmount = 5; // how many points to fade the LED by void setup() { // declare pin 14 to be an output: //analogFrequency(FREQ); pinMode(PF_3, OUTPUT); pinMode(PF_2,OUTPUT); Serial.begin(9600); } void loop() { digitalWrite(PF_2,HIGH); // set the brightness of pin 9: analogWrite(PF_3, brightness); // change the brightness for next time through the loop: brightness = brightness + fadeAmount; Serial.print(brightness); // reverse the direction of the fading at the ends of the fade: if (brightness == 0 || brightness == 255) { fadeAmount = -fadeAmount ; } // wait for 30 milliseconds to see the dimming effect delay(30); }
