Hi,

I need examples or informations about DMA and ADC 16 channels. I saw examples where DMA manage 4 ADC channels.   Thanks

Couldn't you cite the example and specify the processor?

Why not just increase the Channel count, the Rank in the enumerated list of channels, and buffer/DMA length? Your first task would be to identify the 16 channels and pins you want to use in YOUR design. Determine if you want to do this with one or more ADC.

Hi Clive,

thanks for reply. I'm working with STM32F0 and this mcu has 16 adc channels. In my project, I need read at the same time all 16 channels. Is there an example? Thanks

Ok, but I think it has only a few ADC units. They will scan multiple channels, with the conversions slewed about a microsecond between each channel. STM32F072B-Discovery_FW_V1.0.1\Projects\Peripheral_Examples\ADC_DMA\main.c Increase the buffer size, and enumerate more channels. Configure the pins. The F0 is not my platform.
