hello, I'm working with the stm32f4-discovery Board , in fact i have a problem using the DMA with an ADC 'injected channel'. I've configured the DMA to transfer the converted data from the injected data register 'JDRx' to a buffer adressed in the Memory but no transfer operation occurs...I've realy checked my configs and i couldn't figure out what is wrong...thank you for your support.
