  1. Hello, Is it possible to use the XDS110 debug probe with Energia? And if so, how? Best regards, -C.
  2. This snippet does not give the expected results (and I know I should be checking the return code of sscanf()...), the string contains text like "60.0" when asked for a frequency. float request = 50.0f; sscanf(string, "%f", &request); // having trouble since energia version 1.6.10E18 with floats... Under version energia_0101E0015, request becomes whatever float value is in the string (say 60.0), but under energia_1.6.10E18 request remains at the initialized value. Same with this snippet: sprintf(timecodeBuffer, "f# %04d ft %.03f %02d:%02d:%02d.%02d.%03d

    Noise in ADC

    Hi, I have a non-profit (Smoky Mountain Scientific, smokymtsci.com) that develops and sells low cost instruments for science education. One of our instruments incorporates a Tiva-C launchpad that outputs a pwm voltage and measures voltage and current passed in electrochemical reactions. I recently purchased a fairly large batch of Tiva launchpads from Mouser and I am having trouble with noise in the analog read channels for about 1/4th of the boards. We have been building and selling these instruments for a couple of years now and have never had this problem before. To test the boards, I
  4. Hello, After installing E18, and getting the TivaC board package with packages manager, when I try to upload a program into the Tiva-C board I get the following error: fork/exec /home/can/.energia15/packages/energia/tools/arm-none-eabi-gcc/4.8.4-20140725/bin/arm-none-eabi-g++: no such file or directory Error compiling for board LaunchPad (Tiva C) w/ tm4c123 (80MHz). If I go the the mentioned directory, I can see that the arm-none-eabi-g++ executable exists by: $ file arm-none-eabi-g++ arm-none-eabi-g++: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamical
  5. Hy, I worked on a source half a year ago with an older Energia (I do not know exactly which one.). I was able to acces UartIntHandler and UartIntHandler2() functions directly. As I remember I do not change the content of Energia under OSX. Now I try to modify 1-2 things for example in the startup_gcc.c or hardwareserial.c, but the are not working. Can you help me how could I reach the UART interrupt handlers from Energia? (The setup of UART module worked on CCS or IAR before.) Can I use something like attachinterrupt()?
  6. Hello All, Is there any sample program for using the CAN with Stellaris/Tiva-C with energia IDE ? I could see D:\energia-0101E0017\hardware\lm4f\cores\lm4f\driverlib can.c and can.h files. How to include this .h files and have a program which transmit some data Thanks for your support Dino
  7. I am attempting to construct a simple library for creating alarm objects, basically just the days of the week, an hour, and a minute packaged together in an object for easy management. I have attached a zip of the library, (feel free to use any code that might be useful!) but I am having an issue where toggling the days of the week alters the values of the integer hour and minute values. The days of the week are stored as an array of seven booleans, but I don't think that I am making a fencepost error somewhere... I tried the various days of the week, and figured out that days 0-3 (Sun
  8. Hello, I managed to port the MPU9150Lib at https://github.com/richards-tech/MPU9150Lib to Energia. I had to make few changes in defines in dmp code, and the provided CalLib, and now it compiles for MSP430G2553, MSP430F5xx, Stellaris Launchpad, and the Tiva-C series (TM4C123) launchpad. CalLib writes to either flash or eeprom depending on architecture. It has failed for MSP430G2553, due to code size. It compiles for MSP430F5xx although I dont have a board yet to test. I have not tested the stellaris launchpad but I suspect it works, it does WORK on the Tiva-C series launchpad. H
  9. Hello! This is my first time posting, so please let me know if I missed anything! I am attempting to use the TivaWare library to modify the clock speed of my Tiva-C (EK-TM4C123GXL) microcontroller. Eventually I plan to use this to construct an alarm clock, with the timing based off of the accurate crystal on the Tiva-C. When I attempt to compile the following code (largely based off of a library written by Yannick and Graham Fountain) I receive a long list of errors, also included below. Code: #include "driverlib/interrupt.h" #include "driverlib/sysctl.h" #include "driverlib/t
  10. I solder on spare pcb a pcf8563 acording to diagram: PCF is connected to I2c 3 (PD_0 and PD_1). Tiva-C is flashed with code: #include <Wire.h> #include <RTClib.h> RTC_PCF8563 RTC; void setup () { Serial.begin(57600); Wire.setModule(3); Wire.begin(); RTC.begin(); // following line sets the RTC to the date & time this sketch was compiled RTC.adjust(DateTime(__DATE__, __TIME__)); } void loop () { DateTime now = RTC.now(); Serial.print(now.year(), DEC); Serial.print('/'); Serial.print(now.month(), DEC); Serial.print('/'); Serial.print(now.day(), DEC); Serial.print('
