Hi friends.

My problem is the next: STM32F103 adc + dma transmits only low byte of adc data... The same code via adc EOC interrupt presents the whole 12-bit words. I hope, that i missed something very simple. I use ADC3 and DMA2 with EndOfTransfer irq.....Thanks in advance.Yury

Perhaps you're configuring something wrong, should I guess? The width of the DMA is configurable.
