Status of Wire.h for TM4C123 in Energia

[altineller 4]

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
