Dual ADC mode
2011-05-17 03:22 AM
Hi,
I'm planning to use a STM32F103 in dual ADC mode. I want to perform simultaneous sampling on 2 analogue signals i.e. a separate ADC assigned to each signal. I have an external trigger which will initiate a 128 sample burst capture at a pre-programmed sample rate (up to 200kHz) & save the results to memory. As far as I can tell the DMA controller can only work with a single ADC channel. So it seems I'll have to do this under software control or am I missing something? Thanks Dave2011-05-17 03:22 AM
In case anyone else was wondering, after reading the datasheet more carefully it says that that ADC1 & ADC2 results are saved as 32bits to the ADC1_DR which can be copied by a single DMA transfer
