CCS/TM4C129XNCZAD: CCS/TM4C129XNCZAD:

Part Number: TM4C129XNCZAD

Tool/software: Code Composer Studio

I have a some questions about tm4c129.

1. I want to communicate between two boards(tm4c) using I2C. At this time, I am trying to configure CCS on one computer. Is this possible?
If so, how should I structure it?

2. What communication method is suitable for communication between two boards (except UART)?
Also, is there a problem with trying to configure I2C?

    The ICDI (in-circuit debug interface) on the DK-TM4C129x development board does not support having more than one emulator on a PC at a time. You could use an external debug interface like an XDS100V2 through the ARM standard 20 pin connector J1 on one of the boards.

    I2C is designed for short distances, originally designed for between chips on the same board. Also, one must be the master and the other a slave. All transmissions start with the master. If those conditions are acceptable for your application you can use I2C. My first choice for between two boards would be UART. (Any particular reason you are avoiding UART?)
