Hinweise: In bestimmten STM32 gibt es zwei DMA Controller (DMA1, DMA2). I want to use Multichannel ADC using the STM32F4 so I want to read two different AC signals on two different pins/channels. We will write ADC values to memory by using a DMA channel. Урок 16 HAL. DMA를 설정하기 위한 adc_dma_init()코드는 위와 같다. A/D conversion range: 0 - 3. The documentation file is generated in automatic by using DOXYGEN. Now when I read the ADC_DR register and clear and set the ADC_CR2_DMA bit it works like expected (last days trial). In this article we will speak about only Independent mode: Independent modes: Single-channel, single conversion mode: This is the simplest ADC mode. We were waiting for the ADC result in a loop which isn't an effective way of using processor resources.
