AWR1843: Timer interrupt

Sriram S

Part Number: AWR1843

Hi,

I'm implementing AWR1843 in an MRR project. Please let me know how to modify mss_main.c to include a timer interrupt.

Kindly supply the example code for the timer interrupt in mss_main.c. In addition, I'll be sending data in CAN for this project; however, how can I make it transfer in CAN at a rate of 100 milliseconds at once?

Hi Sriram,

AWR1843 uses RTI from TI-RTOS. Can you go through this video for timer interrupt? - Getting Started with TI-RTOS: Chapter 10—using clock (timers) | Video | TI.com

There is some calculation to obtain nominal and data bit-rate (you can find this in Can_Initialize function present in mss_main.c).

With the help of the above snippet, you can modify the nominal and data bit-rate according to your requirement.
