ADC Pin Setup

[SLetter]

I am trying to set up 3 ADC.  I set PA4 to ADC1_INP18, PA5 to ADC2_INP19 and PF11 to ADC1_INP2.  Will this be something that works?  I am monitoring 3 lines (none NEED to be fast).

I'm not clear on how to set this up.  I am multiplexing several inputs onto these, all single ended.  I'm not sure how we will read the data yet, timed, interrupt driven or polled.  I am replacing a LPC3250 and re-implementing the functionality.

The simplest is all three channels on one ADC and DMA to a 3 word buffer with one start command.

See the ADC DMA examples provided with the HAL library.
