Any guidance, documentation links, or example projects would be greatly appreciated.

    Ranjith,

    While we do not have dedicated examples for bit banging, we do have several examples to reference in terms of general GPIO configuration and CPU timers within the C2000Ware device support directory for F2802x (C:\ti\c2000\C2000Ware_6_00_00_00\device_support\f2802x\examples\drivers). I'd recommend looking into these and perhaps using a CPU Timer that matches your baud rate. On the receive, you can also leverage external interrupts on this device which can be selected negative or positive edge-triggered triggered. Here are some examples to reference:

    • cpu_timer example
    • external_interrupt example
    • gpio_setup example
    • timed_led_blink example
    Feel free to create another thread with more specific peripheral configuration questions when trying to implement this. 

    Best Regards,

    Allison
