title: STM32F302 Adc with DMA for different size and channel
body: <p>I'm using STM32F302 QFN32 and unfortunately, it has only one ADC module. One channel must get around 500 samples in one period and it must be sync with and PWM (thinking using a timer and this i/o will be toggled  in callback, because while reading its ADC channel, I must know the i/o whether high or low, so that according to this value, will decide value). Furthermore, there are 4 more channels which must be read.(More samples doesn't need there like before, 8 or 16 samples will be enough.) However, it has only one ADC module. Consequently, Can I do this? If yes, how? Thank you.</p>
