tm4c1294ncpd

having trouble getting started with this board.

not all code for the 123 ports well (in fact most of it doesn't at all so far..).

trying to build a script to call a register, display the value, then allow me to modify the value via and/or commands. I know direct register method is not recommended... just trying to build a simple script here.

So far can't find any register address' let alone call them.

so far i can't even call the LEDs on the board and any code for calling gpio ports for 123 don't seem to work on the 129...

any data sheets or diagrams with address locations and how to call them would be appreciated.

thanks much,

Bryce

    Bryce,

    I would propose the following approaches in porting a TM4C123 project to TM4C129.

    (1) Create a list to map EVERY I/O pin, interrupts, timers, etc from TM4C123 to TM4C129.

    (2) Start from one TM4C129 example from TIVAWare. Make sure that you use the correct system clock setup API for TM4C129. Add the source files for TM4C123 into your project.

    (3) Using list from the step 1, modify the the old TM4C123 code.

    I used this approach in couple of migrating projects. It was straight forward for me.

    Thanks and regards,
