HW: RT1170EVK
I want to transfer ADC value to memory via eDMA
But I am confuse the logic of the trigger chain.
If I activate the DMA request by the LPADC1 module and at the same time I activate the Hardware trigger (to ADC_ETC) (See screenshot below)
Would that mean, the eDMA and the ADC_ETC both are triggered if the RESFIFO is ready?
If I enable the eDMA request also in ADC_ETC, would that mean a conflict of using same eDMA channel?
Hi,
Sorry for the later reply.
Please refer chapter 4 of RT1170 reference manual Table 4-3. DMA Mux Mapping (below picture), which shows the ADC_ETC, LPADC1/2 using the differenct DMA MUX channels.
Wish it helps.
Mike
