Hello

Is it possible to use dual interleaved mode with 2 different DMA channels in stm32f3?e.g one channel for adc1 master and another for adc2 (slave). there is some examples in stm32cube, using one dma channel.

Thanks.

After reading stm32f303 errata, it seems to be the limitation of mcu revision i'm using (stm32f3discovey and Y revision of the mcu) :

'

DMA overrun conditions can be encountered when two ADCs are working in dual

interleaved mode with a single DMA channel for both (MDMA[1:0]bits equal to 0b10 or

0b11). This limitation applies in Single, Continuous and Discontinuous mode.

'

So what are the other revisions of this mcu available?
