I have set up a project in a cube. SPI + DMA. When the mcu sends data from the stack, the DMA works fine and activity is visible on the pins. But if allocate an array of data in bss as static or global, then nothing happens on the pins. The program r...

I config ADC with DMA and TIM2. By TIM2 overflow starts ADC process for ADC1 ADC2 and ADC3 simultaneously. DMA collect ADC data and store to RAM. In debug i see that DMA for ADC1 transfer the same ADC data several times.For example:ADC1: 32, 32, 32, ...

Hello. I have stm32f407 MCU. I need read 6 ADC channels by timer (2 Khz) and store adc data to 6 circular buffers. What is better way do this?

On picture - in arrADC3 - data from two adc channels. It OK. But in arrADC1 - repeated data from only one channel!

I use 3 DMA stream and 3 data buffer. In debug all stream DMA registers are similar. But data buffer for master ADC1 filled by repeated data.
