Hi,

 

I have a few questions related with PPI;

 

first one is; how to increase sample count above 65535 due to sample count register is 16-bit but need more sample. DMA0 is used to transfer data.

 

second one; what is the minimum sampling rate (PPICLK) of PPI? the maximum is bus clock/2 but i could not find the minimum. Why i m asking is i produced pwm signal around 20 MHz and drive PPI. This resulted with unexpected behavior like missing samples or hitting expection.

 

Could you please inform me?
