It works with DMA_CIRCULAR (but I do not want or need continuous DMA transfers.)You see by the terminal output below that reading 2 analog inputs works OK. However, after a while (< 1 minute) the 2 analog values are exchanged now. Apparently the DMA ...

Hello,Under linux (project generated by STM32CubeMX), the compiler reports illegal implicit casts from void * to PCD_HandleTypeDef in the HAL libraries.The problems are in two files: usbd_conf.c and usbd_cdc.cI solved this by following the example in...

This is the complete clock configuration

Jwork.1 · 2020-02-16

Not sure if the picture of the clock configuration will get scrubbed, so:AHB clock = Is that the same as HCLOCK? I know that Hclock= Sysclock/1= 72MhzAPB1 (peripheral) clock = 36 Mhz, APB1 timer clock = 72MhzAPB2 (peripheral) clock = 72 Mhz, APB2 ti...

Having become suspicious of the USB library, I tried 3 experiments this morning.My conclusion is that all my ADC problems are caused by the USB library.Experiments:1. Replace USB logging by UART logging (but leave the rest of the codeuntouched) T...

Again logging around the point where the "sync is lost". Code:sprintf(message, "%d %d\n", adc_buf[0], adc_buf[1]);serial.USBwrite(message);HAL_Delay(100);sprintf(message, "ADC1->DR=%lu, ADC1->SR=%08X, DMA1->CNDTR=%08X\n", ADC1->DR, ADC1->SR, hdma_adc...

Ok I wrote the last part too quickly.I guess the result of the manual read directly after ADC/DMA get out ofsync is NOT what I expect.Below is a new log around the point where the DAC readings in the memorybuffer get switched. Above this point the m...

Why does the DMA gets out of sync when doing a sequence of regular AD conversions on stm32f103C8TX? This only happens with DMA_NORMAL.

STM32CubeMX generates HAL library code that does not compile
