Hello all,
I need some help with DMA. I read a lot of examples and application notes, but I am not able to make my firmware work. I am working with TWR-K64 board and Kinetis KDS v3.2.0 with Processor Expert (no SDK). I would really appreciate your help.
The background is as follows:
At this beginning, I am working only with the TWR-K64 board without the external ADC (so I assume that PORTC always will be zero as the external ADC is not connected). The PTD5 pin and Yellow led are displayed in the oscilloscope.
When tact switch SW3 (from TWR-K64) is pushed, the led turns on and the PWM starts, and both should come off after 8 PWM periods in the event “DMACH1_OnComplete” .
However it does not work. Please find attached the project in case somebody could have a look.
Thank you in advance.
