Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Gradually debug the DMA send function, HAL-UART Transmit DMA, and find that the function will judge a status bit of the serial port handle, gState. It will only send normally when huart ->gState==HAL UART State READY,And the reason why the first tran...
It seems that STM32H563MI has four I2C ( I2C1 ~ I2C4):However, the corresponding STM32H563.svd only includes 2 I2C ( I2C1 ~ I2C2).https://stm32-rs.github.io/stm32-rs/STM32H563.html
SEE EDITI am using the STM32H7B3I-DK. I am trying to write my own simple SPI ISR to handle transmitting and receiving of just one byte I have gotten the slave working with my ISR (while master used HAL). I am now implementing on the master and having...
I am using STM32H7B3I-DK running a touchgfx application and acting as SPI Master, and Nucleo-H743ZI as SPI Slave. Both are configured in interrupt mode not using HWNSS. The Master is sending 0,1,2,3,4,5,6,7, but the slave is only receiving 0,2,4,6,0,...
Hi, I have a custom PCB where I am attempting to bootload an STM32G071CBU6 (using an STM32U575). I am using the bootloader while developing for uploading development builds, so it is being used often. The G0 seems to occasionally, randomly, stop resp...
Using a Nucleo-F411RE board modified to have 8MHz HSE crystal oscillator and running the OTG peripheral in forced host mode, we are working on implementing our own host stack. With the current code no IRQs trigger until a device is physically attach...
The Ethernet reset is not clearing (ETH_DMABMR_SR in DMABMR).I am having a similar issue as others but have not seen a solution in the forum.I am working with the stm3210c-eval board. I know it is no longer available; but it has a version of the proc...
Hi, Looks like the HAL driver for the STM32f7xx ADC is missing a case for using the software start of the ADC2 peripheral in the HAL_ADC_Start_IT function. Starting from line 1128: else { /* if instance of handle correspond to ADC1 and ...
Hi, I am having a strange ADC problem on my STM32L431 device. I am sampling 6 channels without DMA using polling method with the following code: while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ ADC_Select_CH0(); HAL...
Hello,I have been trying to read/write into an SD card using the SPI or SDMMC method with Fatfs. I wasn't able to make use of the filex option for file operation which is provided in the STM32u5A9 libraries, since I am using FreeRTOS in my project (a...
