Hello,
I'm using an nrf9160 to count the number of falling edges on a GPIO pin using a timer without any processor intervention, aside from capturing the number after some interval elsewhere. It sounds like DPPI is my best bet, but I can't seem to find any information about my specific use case outside of the Nordic documentation.
My method of capturing the timer value doesn't seem right, but I haven't found any resources telling me so. I'm experimenting with S and NS configurations since there's a line that reads "non-secure peripherals can only subscribe to non-secure channels". I'm seeing quite a lot of potential areas where my logic may be broken, so I was hoping to get some direction as to why my code doesn't work properly.
Thanks in advance
