As I asked here https://community.nxp.com/thread/469445#comment-993599 I want to know if it is possible to trigger the ADC at different times over one pwm period with KV4x. I found out that with an additional pre-Trigger in the PDB_Config block the End of Scan Interrupt occ...

Referring to your answer, I exported the trigger signal of pwm master(ch0) to PWM CH11 to create an ad trigger signal that changes edge when CCU0TC interrupt (which occurs when CN0 and CM0 match) and CCU1TC interrupt (which occurs when CN0 and CM1 match)It was also confirmed that the...
4. The rest is managed by the DMA_ADC using single descriptor that is required to capture 10 readings, 20ms apart. Now I am trying to do this using DMA to avoid the 10 x 20ms delays in runtime. I am using EOS that triggers the DMA. But the slowest SPS is ~1,700, I only ne...
