Hi everyone,I am trying to generate an arbitrary PWM waveform using DMA burst write according to AN4776. It works in principle, except of one thing: If i want to have more than one pulse with a specifig period/pulse setting, the RCR should be used. H...
Hi,We have a question about a system design we would like to implement for our product.We are working with the STMF32F723 MCU and are developing our own HW. We need 216MByte of RAM for our application and would like to implement it with the functiona...
Hello! I'm using USART with DMA and when I disconnect the Rx cable, sometimes the communication resumes and sometimes not. How can I always recover USART Rx?I tries reseting it with RCC using the line: RCC->APB2RSTR ^= RCC_APB2RSTR_USART1RST; // USAR...
All,I'm finding that concurrent DMA driven SPI transfers are failing.its STM32H743, Latest HAL, latest Cube and followed all rules with cache configuration etc etc.I’m running this in different FreeRTOS threaads and if I put a mutex around the HAL DM...
Hi, I'm having a problem with unintentionally splitting a message I'm trying to send over the UART using DMA . I am using one function to send the message:const uint32_t max_value_of_counter_loop = 100; /* in case systick jams */volatile bool was_u1_...
I'm following the example the USB MSC Standalone example provided here:https://github.com/STMicroelectronics/STM32CubeF4/blob/master/Projects/STM32446E_EVAL/Applications/USB_Device/MSC_Standalone/Src/usbd_storage.cI am attempting to get the eMMC that...
I am trying to create a repeating trigger to start an SPI transfer to read 12 x 16 bit values from an external ADC.I have configured the SPI with a Rx DMA to receive the data and have created a timer to trigger a second DMA to write to the SPI->CR1 r...
Trying to get a basic sample DAC1 with DMA, triggered by TIM2 working. This should be trivial, works fine on SMT32F3. I'm using a Nucleo-32 SMT32G431.Using Cube IDE. The only non IDE-generated code in main is: /* USER CODE BEGIN 2 */ static uint...
Dear all,I'm currently using the STM32MP157F-DK2 series, and I'm trying to use the ADC1 and ADC2 in dual regular simultaneous mode triggered by TIM2 out event. Also, I used one DMA stream (DMA2_stream0) to read the ADC values of the Common Data Regis...
Hi, I am new to STM32. I have a STM32H723 nuncleo board where I want to sample 8 bit data from the on-board ADC at the maximum frequency of 3.6 MHz. Then I want to directly transfer the data to a SD card using DMA with SPI. Preferably I would want to...
