  1. Hi Guys Your drawing/jpeg link on page http://energia.nu/pin-maps/guide_cc3200launchpad/ is broken. can someone pls point out the pin numbering for the cc3200 launchpad for me with regards to digitalRead() ? I found this diagram in the cc3200 hardware document. Would one then just use digitalRead(57) for pin P3-3? Secondly, does anyone know what registers to read if you want to read all the bits at once? For example in the arduino you could just read PORTD ? What are the registers for the cc3200 on the launchpad? Many thanks Paul
  2. Hi, The new MSP430FR2433 ValueLine Launchpad is with a promotional price. https://e2e.ti.com/blogs_/b/msp430blog/archive/2017/11/08/introductory-price-of-4-30-for-msp430fr2433-mcu-launchpad-kit?HQS=epd-mcu-msp-vline-fb-blog-LPdiscount-wwe&hootPostID=97a463d63a1e96cbf999f3c7a33c703e It seems to be a good replacement to the old ValueLine G2
  3. Hi All, I am trying to measure some timing properties of a protocol I have written that uses the EasyLink library. I was using micros() before and after I perform a send, which also waits for an acknowledgement. In addition to capturing micros() I am toggling a pin so I can see how long the event takes on the scope, and when the corresponding events happen on the other CC1310. micros tells me the event took ~1400uS, however I measured about 33ms on the scope, I then replaced micros with millis() in my code and I am getting 33ms from that as well. I would really like to be a
  4. Hi, Wondering if anyone can confirm if the MSP430 source code listed in this article can indeed be used with Energia (IDE and library) ? Idea being mixing Energia library for AnalogRead and SPI data sending capability. Also, I'd like to use the LP with MSP430G2553 to perform ADC for 6-8 channels, and convey the same to RaspberryPi over SPI using this mechanism. Given the very limited RAM on MSP430G2553, what is the likelihood of being able to squeeze in such functionality along with the SPI communication ? Pointers to any existing projects at achieving similar goals, would be hi
  5. 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 ?
  6. 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 se
  7. 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
  8. 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 http://www.ulisp.com/.
  9. 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: https://dev.ti.com/gc/designer/help/Tutorials/Serial/index.html. 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 d
  10. 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 vol
  11. 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_CC13
  12. 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
  13. 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
  14. 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(" e
  15. 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 CCxxxx.zip
  16. 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!
  17. 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 on
  18. I was trying to get the Tiva Launchpad TM4C123 working with the Nokia 5110 using Energia. Eventually I came across this page: http://www.clarenceho.net/2015/08/tm4c123-with-dht11-sensor.html 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 com
  19. 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!: https://www.youtube.com/playlist?list=PL_atu5RtEPi5I5YWx_wb_j9erZGCvnpvW EDIT: I have watched a few more of these and apparently they are TI sponsored.
  20. 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 re
  21. Ti dropped a new launchpad today, it isn't even listed on the ti.com/launchpad page. From the email: "the world
  22. 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.
  23. 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
  24. This library allows you to quickly and easily connect your LaunchPad project to Exosite's Data Platform in the cloud. It connects your project using a MSP430F5529 LaunchPad and CC3000 BoosterPack. Two software packages are available: the Exosite barebones-template solution and a real-world example in the form of the Exosite BBQ Companion Combination. Both of these use-cases have code available for the Energia and Code Composer Studio IDEs. Present Support: MSP430F5529 LaunchPad Future Support: Tiva C Series TM4C123G LaunchPad Required: CC3000 Wi-Fi Transceiver BoosterPack Optional: ADS1118 B
