Dear Expert, Can you provide an instance for pulse output (eg:100KHz) with PRU of AM2431? Thanks~

Hi Yangbo,

I assume you're asking for PRU code to generate a 100 kHz square wave? I'm unaware of an example for AM243x, but there is a PRU GPIO toggle example in the PRU support package for AM335x/AM437x. It should be possible to modify this example for AM243x.

Please see:

https://git.ti.com/git/pru-software-support-package/pru-software-support-package.git, <root>\am437x\PRU_gpioToggle

The example is written in C, but it should be relatively simple to translate it to assembly language if needed.

Regards,
Frank
