I want to use ADC-DMA to read 4 input of voltage. PA0, PA1, PA2 and PA4 on ADC3 IN0, IN1, IN2 and IN4.

I try to modify the code samples founded in STM32F4xx-Discovery_FW_V1.0.0 for STM32F4-DISCOVERY or for STM32F429-DISCOVERY but both don't work (my code) on theses boards.

In final i must read this four ADC inputs with a stable frequency, i want to use a Timer.

Someone can help me with sources please?
