Question

Ethernet (on board) and a few ADC on STM32F429 at the same time?

Using CubeMX with my NUCLEO-F429ZI Board, I can configure 16 inputs on ADC1.

However if I try to activate the on-board ethernet there is a conflict.

So I tried to first configure ethernet using RMII interface with no ADC activated.

I then try to activate ADC1 it shows inputs 1,2,7,11,14,15 as unavailable (because those pins are being used by the ethernet interface). However, it appears the other ADC inputs are available.

Further, it looks like ADC3 has fewer pins in conflict (1,2,11) leaving 13 AD channels available.

Am I correct or all wet?
