I hope someone can help me with my problem. In a recent post I talked about my problems getting DMA work with the ADC. This does work, sort of.Now to my problem: The ADC is triggered by a timer update event. Then the data is transferred via DMA to a ...

I've set a breakpoint and then took a look at the buffer. This should show the real data, shouldn't it?

dev->buffer is a 16 bit double pointerSo dev->buffer[0] is a single pointer as it should be> You do youI mean, I tried it. And as I said the compiler throws a warning about the implicit type cast, but nothing else changed. I just tried it again to co...
