STM32F107VCT6 core is locked-up after programming
There are two identical controllers with STM32F107VCT6. One of them is programmed, and another one is not. Memory protection is disabled. I haven't the original program project, and the task is to read and save program from the first controller and d...
Problem with SPI5 in stm32h747-Disco
Hi, I have imported the example project TX_CMSIS_Wrapper and I wanted to integrate SPI5 with it. After initialising SPI5 I could not see any clock signal generated. I am using STM32H747-DISCO development board. void MX_SPI5_Init(void){hspi5.Instance...
Resolved! ADC_VRef in STM32L431RBT6
I'm trying to use the internal reference voltage of 2.048V in my application, since I'm powering the microcontroller with 2.8V. But when I select the reference source and enable the VRefBuff with this lines: HAL_SYSCFG_VREFBUF_VoltageScalingConfig(S...
Missing CAN frames in STM32F205
HI , I am having an issue with STM32F205 controller CAN rx message reception. We used cubemx to generate the CAN driver at the baud rate of 250kbps. we want to receive CAN messages around 1100 messages per second. but we are missing CAN frames above...
STM32H750VB_UART_DMA_Mode
I have enabled DMA for usart2 in pins PD5 and PD6 and I have attached my main file. I have tried uart transfer by polling mode and interrupt mode both are working fine. But when I try for DMA mode the data is not transferring .I don't know where I ha...
Resolved! HAL delay doesn't match the value
I am using an STM32 MCU. When I use the HAL_Delay function with a parameter of 1000 for example, I see that the delay is shorter than it should be. I have checked that HAL_IncTick(), but it works correctly and it is placed inside the SysTick_Handler....

What's the suggested way to mix C and C++ sources in STM32CubeIDE
Hi, I'm using STM32CubeIDE to develop firmware for a small appliance (using STM32F303) in C++, but I'm in troubles related to the build process, caused by generated files like stm32fxx_hal_mps.c including C++ headers, while being compiled with gcc.Wh...
Resolved! Can't communicate when use 500K and 5M Bit Rate
Hello, everyone,I test CANFD a long time. And I found that some Bit Rate doesn't work together. For example, I use CANFD Mode, set to 1M + 5M. It work well. But same parameter at Data Bit Rate，I change to 500k + 5M， or 250k + 5M， it can't work. It al...
