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

Hello, I am having a problem using the the Wire examples in energia, master_writer and slave_receiver. I have not modified the code in the examples and just want it to transfer the information across, so that I can work on from there. The two boards are connected together with sda to sda and scl to scl, it shares a common ground and both boards have a 5V supply to the 5V pins However, every time i connect the boards and check the serial monitor on the slave board, all i see is weird unique characters. When i press reset button on the slave board, it will repeat and print the same weird character. I'm fairly new to i2c communication and would appreciate any help provided here, Thank you, Danial.
