The DMA is a great tool to use with the ADC when you want to transfer lots of samples to memory continuously. A analog signal varies in voltage with multiple values, hence the need for a ADC. The idea is that the PWM module provides a short (about 1. We'll simply peek at the buffer contents in the STM32CubeIDE debugger to show how the DMA can act without CPU intervention. There are I2C environments where multiple masters are driving the bus. Configure ADC for X channel with DMA without Interrupt (DMA should be in circular Mode) In software for Y point for averaging of each channel, request HAL_ADC_Start_DMA with X*Y point; When you want to read a channel known point in memory, without checking ADC …. One solution i’m thinking of is to have the “DMA memory map” (x4000_8100 to x4000_813C) stored in a array, then the second dma channel would copy this array to the processor. You could imagine a multitude of applications based on the STM32 ADC features. The project that I'm working on requires me to simultaneously read 6 analog channels (with a reasonable data rate). 4) DMA different transfer modes: M2P, P2M,M2M.
