  1. Check the usual suspects: Is the I²C bus initialised? Wire.begin(); Does the I²C device run at 3.3V? Otherwise, use a logic-level converter. Are pull-ups installed? Try 10, 4.7 or 2.2 kΩ for the SDA and SCL lines. In case the LaunchPad provides multiple I²C ports, is the correct port selected? Try Wire.setModule(0); // or other port number Wire.begin(); Still nothing? Use a logic analyser to trace the signals on the I²C port. (To be continued...)
  2. Model of LaunchPad: MSP430G2553/G2403 and revision number: 1.5 Model of the MCU used: I am not sure, but the box is MSP-EXP430G2 Name and version of the IDE used : Energia version 0101E0017 (I tried the newer one, but it threw a bunch of errors which resolved when downgrading) OS the IDE is running on Ubuntu 16.04 LTS I am completely new to this type of programming, so I apologize if I need extra clarification or am missing something. Issues faced: The blinking code I have used all work just fine, but no print statements work. My current goal is to simply get a read from the internal temperature sensor, but printing won't work. I am attaching relevant screenshots. and example code. Any direction/help is appreciated! Blink.ino
  3. Is there a full energia porting for msp430fr5969, i.e. all the ports and full mcu functionality (timer, spi, i2c etc) rather than limited as per the launchpad? I have msp430fr5969, custom board connected to bunch of sensors and radio and would like to use energia for this. Any directions or suggestions will be most welcome. Thanks
  4. Hi everyone, I am using a Black Launchpad and this does not work in the latest version of Energia which is 1.6.10E18. So I switched back to the version 0101E0017 to make use of the Black Launchpad. My code is below and tried in Arduino IDE and working fine: float a = 3.5; float b = 2.0; float result = 0.00; void setup() { // put your setup code here, to run once: Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: result = max(a,b); Serial.println(result); delay(1000); } Using the same code in version 0101E0017 produces a compilation error that "max" was not defined. In 1.6.10E18, this works but it is impossible to upload this program using the Black Launchpad. Any suggestions for this error? Thanks and Good Day, Leo
  5. I'm using the latest version of Energia and I'm facing some problems with it. I'm a beginner and I tried running an example program on the MSP430G2553. I get this error which says: Energia: 1.6.10E18 (Windows 8.1), Board: "MSP_EXP430G2553LP" In file included from C:\energia-1.6.10E18\hardware\energia\msp430\cores\msp430/Arduino.h:3:0, from sketch\Blink.ino.cpp:1: C:\energia-1.6.10E18\hardware\energia\msp430\cores\msp430/Energia.h:339:26: fatal error: pins_energia.h: No such file or directory compilation terminated. exit status 1 Error compiling for board MSP_EXP430G2553LP. This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. Please help me in getting rid of this error. Thank you!
  6. I was not able to use realloc using energia so I imported the proyect to CSS v7. It seems there is something wrong or not done about realloc under Energia. CSS v7 is using the Ti compiler instead of GCC and it has realloc and it works. But when using CCSv7 with the imported sketch, the Serial.print commands do nothing. Even If I debug step by step it just ignores Serial.print commands without showing anything anywhere. I activated the serial terminals inside CCSv7 to see the output and I also have the normal output and the console. I can work around if I find a function equivalent to micros() for the CCSv7
  7. i bought two Mspexp430 launchpad with two cc110l rfand i could to programm them in energia : then i want to add more nodes on the Network so i bought two new Mspexp430 launchpad with new two cc110l rf and they work correctly on ATC boostersatcklite but when I want to program them on energia I can upload the code but the cc110l doesn’t exchange any data from each other , i tried also with the examples in energia (wirlessControl-WirlessTest-WirelessMonitorhub-WirelessmonitorSensor) but they did not work Can you help me to let them work correctly and exchange data
  8. Hi all, I am currently just trying to upload a example sketch to my MSP430G2553, all i'm getting is a compile error. The github library is; https://github.com/ibm666/ILI9341libraryforEnergiaMSP430Launchpad what im getting error wise is; In file included from D:\energia-1.6.10E18\libraries\ili9341-arduino-master\examples\drawNumber\drawNumber.ino:8:0: D:\energia-1.6.10E18\libraries\ili9341-arduino-master/TFTv2.h:33:17: fatal error: SPI.h: No such file or directory compilation terminated. Using library ili9341-arduino-master in folder: D:\energia-1.6.10E18\libraries\ili9341-arduino-master (legacy) exit status 1 Error compiling for board MSP-EXP430G2 w/ MSP430G2553. Can anyone tell me what i'm doing wrong? I can upload examples from the SPI library so im assuming it cant be that?! HELP!!! PLEASE!!!
  9. Hello, What is the status of Wire.h when using energia with the tiva-c board? Since there is the BoardManager in E18, the file layout has changed. Which leads to some confusion. eagle@daredevil:~$ find . -type f -name "Wire.h" ./.energia15/packages/energia/hardware/msp432/3.8.0/cores/msp432/ti/runtime/wiring/Wire.h ./.energia15/packages/energia/hardware/msp430/1.0.2/libraries/Wire/Wire.h ./.energia15/packages/energia/hardware/tivac/1.0.2/libraries/Wire/Wire.h ./.energia15/packages/energia/hardware/msp432r/5.6.0/cores/msp432r/ti/runtime/wiring/Wire.h ./bin/energia-1.6.10E18/hardware/energia/msp430/libraries/Wire/Wire.h ./bin/energia-1.6.10E18/hardware/energia/msp430/cores/msp430/Wire.h So I think when using energia with tivac, it will use the .energia15/packages/energia/hardware/tivac/1.0.2/libraries/Wire/Wire.h file that is in the hidden .energia directory right? Then I went ahead and edited the Wire.cpp file in the tivac/1.0.2 dir. #include <stdlib.h> #include <stdio.h> #include <string.h> #include <inttypes.h> #include "wiring_private.h" #include "inc/hw_memmap.h" #include "inc/hw_types.h" #include "inc/hw_ints.h" #include "inc/hw_i2c.h" #include "driverlib/gpio.h" #include "driverlib/debug.h" #include "driverlib/interrupt.h" #include "driverlib/rom.h" #include "driverlib/rom_map.h" #include "driverlib/pin_map.h" #include "driverlib/sysctl.h" #include "driverlib/i2c.h" #include "Wire.h" Here is a list of include files from Wire.cpp. So here is my question: is this Wire.cpp implementation is for TM4C? is it using or based on the TivaWare Peripheal library? I intend to make some modifications for it, for example using 2 i2c ports at the same time. So I need to start at the correct place. Any ideas / help greatly reccomended. Best regards, CA
  10. Dear developers, I am simply using Serial.println(); command, but I get some weird characters in the serial port display window. Code : #include <Wire.h> // HIH6130 I2C address is 0x27(39) #define Addr 0x27 int tzero = 196; int tspan = 17; int hzero = 196; int hspan = 17; void setup() { Wire.setModule(1); Wire.begin(); pinMode(P1_3,OUTPUT); pinMode(P1_2,OUTPUT); pinMode(P1_6,OUTPUT); Serial.begin(9600); Serial.println("OK"); delay(300); } void loop() { unsigned int data[4]; // Start I2C Transmission Wire.beginTransmission(Addr); // Select data register Wire.write(0x00); // Stop I2C Transmission Wire.endTransmission(); // Request 4 bytes of data Wire.requestFrom(Addr, 4); // Read 4 bytes of data // humidity msb, humidity lsb, temp msb, temp lsb if (Wire.available() == 4) { data[0] = Wire.read(); data[1] = Wire.read(); data[2] = Wire.read(); data[3] = Wire.read(); } // Convert the data to 14-bits float humidity = ((((data[0] & 0x3F) * 256) + data[1]) * 100.0) / 16383.0; float temp = ((data[2] * 256) + (data[3] & 0xFC)) / 4; float cTemp = (temp / 16384.0) * 165.0 - 40.0; // Output data to serial monitor Serial.print("Relative Humidity :"); Serial.println(humidity); Serial.println(" %RH"); Serial.print("Temperature in Celsius :"); Serial.println(cTemp); Serial.println(" C"); Serial.println("=============================================================== "); int VcTemp = map(cTemp, -5, 125, tzero, tspan ); int vhumidity = map (humidity, 0, 100, hzero, hspan); analogWrite(P1_2, VcTemp); analogWrite(P1_6, vhumidity); delay(1000); } Serial Output : (in one single line, means it keeps printing these characters in just one line on and on.picture : Thax.
  11. I don't know why but my energia is running very slow. All the other apps are running at good speed. I am using windows 10 64-bit version. I am using Energia V17. Pictures from my task manager are attached here, please take a look at it. Thax and peace.
  12. Hello everyone, I'm trying setup pwm frequency for tiva C in Energia but failed at this line: analogFrequency(PWM_FREQ) // define PWM pins #define PWM_1 PD_6 // define PWM frequency #define PWM_FREQ 20000 void setup() { pinMode(PWM_1, OUTPUT); analogFrequency(PWM_FREQ); } void loop() { analogWrite(PWM_1, 50); } Can help me with the problem, thank!
  13. Hi, I am having trouble when trying to set the Serial Port and the Board. The options that it shows on the Guide for Mac to choose aren't options shown when I go to the tool tab on my Energia app! Please let me know!
  14. Hey everyone, I am trying to reduce the power consumption of my msp430FR4133 by reducing the clock speed from 8MHZ. I am using the http://annem.github.io/ADXL362/ example code as a base which sets the default clock speed to 8MHZ. I have read that the Wiring.c file defines the clock speed but I cannot find where F_CPU is defined. Any help would be greatly appreciated thanks.
  15. i am facing a problem of slow running energia from last few months but found no solution. energia ide 1.6.10e8 is installed on my system and it takes 5 min just to verify the blink led example which is simple code just imagine how ,long it would take to compile big codes antivirus is turned off if anyone there can sort out this would be really grateful,thanks.
  16. Hi, Greetings of the day, We are trying to access serial flash memory onboard Launchpad of CC3220SF using energia. Please help us in how to read/write to flash memory on CC3220SF. Further suggestions would be of great help. Tried to use SLFS, but compile errors.. Energia: 1.6.10E18 (Windows 10), Board: "CC3220SF-LAUNCHXL (80MHz)" Build options changed, rebuilding all C:\Users\Krishna\Documents\Energia\libraries\SLFS-master\examples\SLFS_Simple_Print_Read\SLFS_Simple_Print_Read.ino: In function 'void setupSLFS_Simple_Print_Read()': SLFS_Simple_Print_Read:30: error: '_FS_FILE_OPEN_FLAG_COMMIT' was not declared in this scope FS_MODE_OPEN_CREATE(512, _FS_FILE_OPEN_FLAG_COMMIT));
  17. I am having trouble importing Energia projects into Code Composer Studio. The reason I want to do this is because I have other Energia projects that use specific libraries, and I am looking to debug them. I took the Blink example from Energia and saved the project to a new location. I have verified this, and it compiles successfully. I then opened Code Composer Studio, and imported the Energia Sketch to my workspace using the wizard from the menu button. The operation summary window popped up, and told me an issue was encountered, "Warning: Resource 'wiring_analog.c' already exists! Ignoring..." I clicked "Ok" and then tried to build the project, but it failed to make the project, citing the message in the attached picture. If anyone could help with this issue, it would be much appreciated. Thanks, Yeshy
  18. Hi, I am using MSP430 launchpad with G2553 controller. When I am using sleep(5000), and varying the voltage on the controller from 3v to 4v the timing is varying based on the voltage, but the timing in not changing when I am using delay(5000) when I am varying voltage. Any help will be appreciated. Regards,
  19. Hi, How can I use UART interrupt in Energia? I tried but could not find any example or sample work.
  20. Hi, I am trying to play audio using a speaker with the help of CC3200MOD and Audio Booster Pack. I have got example code in CCS and it is working fine but most of my codes are written in Energia, therefore, I am trying to use Energia to code Audio Booster but I could not find any documents or examples. do you have any example codes on Energia? Kindly, share the link, it would be really very helpful to me. Thanks.
  21. 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 ?
  22. Please guide me how to port a library for energia or create one myself. I want to create library for SD card and Adafruit GFX. I will share it on Github and in this forum afterwards. Thank you.
  23. Hi all, I need to import/upload data to my MSP432P401R to call upon in future programs. Since I want this data to exist and be saved when my MSP432 is offline/powered-off, I decided that saving it to flash is the way to go. However, I don't know how to do this. Can anyone offer guidance or suggestions? Or does anyone have a better way of doing this? I'm using Energia v18.
  24. I wrote a sketch to fire 2 outputs back and forth with a pot to adjust the on time of the outputs and a pot to adjust the off time. The outputs are just LEDs for now and there is a 3rd LED that turns on when either output is on (so I can adjust the pots later when the outputs are only driving silent, solid state relays.) Every time the MSP430G2553 is powered up or reset, in the Launchpad or a bread board, all of the pins configured as outputs go high for about a second before the program starts to run There is a thread that comes up with a google search of the problem where everyone just accepts that this is what the MSP430 does but it seems to be something that the underlying Energia code is doing because the C code does not make this happen. I altered the Blink source file in CCS to make the 2 onboard LEDs toggle back and forth. When the board is powered up running that code, both outputs don't go high. The LEDs just start to toggle back & forth as programmed. Has anyone else dealt with this? I really can't have all the outputs turn on at the same time with my project. Is there a way to write the Energia sketch to avoid this or do I have to learn how write my code in C? I hope you can excuse my ignorance. I just started trying to program a week ago. I took it up to make this one project when I decided it was going to be a little too complicated to build with discrete components. I really appreciate any help/advise.
