KL27 - Read multiple ADCs + DMA

Hi,

 

I am reading an ADC connected to a DMA at 20Khz at input A, triggered by PIT. However I need to read other 03 ADCs at 100Hz.

 

Is not possible to squeeze these 03 adc readings in between DMA interrupts because the 20KHz ADC start to miss some bytes. Input B is only hardware triggered and I am not able to get readings from those other 03 ADCs from a simple timer.

 

Does anyone have a sample code with a similar solution?

 

Thank you so much,

John
