STLink virtual com port driver digital signature verification problem
After connecting a STN32H735G-DK board to my windows 7 pro pc, the com port driver gives an error "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file ...
STM32F3 DMA triggered by ADC triggered by TIM without HAL
Hello,currently I'am working on a STM32 project with the CMSIS core. I want the ADC getting triggered by a Timer (TIM3). Iam trying to do that with the TRGO option.The ADC should sample 4 different channels. Each channel then gets transfered by the D...
Weirdest thing happening with STM32H7 I2S hardware
Hi guys! I am having the biggest issue with the I2S right nowWhat is happening: For whatever reason the I2S does not want to transmit any samples VIA DMA. Doesnt matter what I do what I try.The weird thing happening: The I2S WS, SCLK wont work. Only ...
UART not receiving NULL hex bytes on STM32F103C8T6.
I'm using STM32F103C8T6 processor with an 8MHz internal clock, 9600 baud rate, 8bit + 1stop bit and no parity. For receiving uart data, I'm using a global interrupt. While I'm receiving data with usart1 or usart2, I can not receive null bytes. Now I ...
STM32H7 Using SPI with DMA circular mode
Hello,i currently use SPI interface of my STM32H7B3I board with DMA (mode circular) to build up a connection to Raspberry Zero W (using Python spidev-lib).At the beginning, I start HAL_SPI_TransmitReceive_DMA() where the data exchange is initialized....
I want to know the parallel communication
Hello All,If I pass 0x38 hex value into my function, that should be came out from my one of the port as parallel data, how to do this ? please give me a simple example with code and explanation.My youtube channelStm32user

Hello, I have several modules with STM32F103C8T6 (called Blue Pills). But I cannot get them to runthe programs. I can freely write or read flash memory with stm32cubeprogrammer, but there is always warning (even when I want to start the program), tha...
Resolved! Write and read using Flash memory on STM32F7xx (24 sectors)
I've got the following structure to write to memory:```#define FLASH_CONFIG_START_ADDR ((uint32_t) 0x080E0000)#define FLASH_CONFIG_END_ADDR ((uint32_t) 0x080E0040)union NVRAM { Config_t config; uint8_t data[512];} DevNVRAM;```I've used this code for ...
Resolved! Hard_Fault handler error on API call for basic UART driver for Nucleo-F303RE
I was trying to write a simple UART driver using polling method to run on my Nucleo-F303RE. I tried 2 different approaches:I wrote the function intpolldriver() to write an integer value between UART4 and UART5 in the main.c, called it in main() and c...
