Aa error occurs when the internal EEPROM(0x08080000) is written to 0x00

The following test code, when writing pTemp[3] to EEPROM, that is, when writing 0x00 to internal EEPROM(FLASH 0x08080000), an error will occur. Calling library function DATA_EEPROM_ProgramByte will have the same error. What causes it? Will it be due ...

I can only access the data from one ADC when in Dual Regular Simultaneous Mode using DMA.

Hello All, I'm attempting to get two ADC's to simultaneously sample on a STM32H743. I have tried both the NUCLEO board and the EVAL board and have not seen much success. I'm using STM32CubeIDE to configure everything and STM32CubeMonitor to monitor ...

STM32F030 HAL_UART_Transmit problem

Hi,I am trying to receive and trasnmit data with STM32F030C8 mcu, i can receive any data from serial monitor, but when i try to use HAL_UART_Transmit to send data, i can not see anything on serial monitor. Any advise?uint8_t data[25];//this my data b...

On my STM32F103C8 my code execution jumps intoto Error_Handler() function but I cannot find who generates the error?

I have a simple code I'm using I2C and TIM2 timer interrupt at 100us. Initially I suspected the issue comes from HAL_TIM_PeriodElapsedCallback but the code inside this function is really few instructions.In the main.c there are two calls of Error_Ha...

Does STM32-MAT/TARGET supports stm32g0 series of microcontroller

We are using STM32l412 microcontroller in one of our project but every time if we need to flash the firmware we need to power the target board USB is not powering the controller while programming

How to send 32 bit data on HAL_SPI_Transmit

I want to send uint32_t spiData1 = 0x48240000; using HAL_SPI_Transmit func but I'm unable to send this data.How can I do the following thing.

HSI48 and CRS accuracy issue

Hi all, I am using the STM32H755 Nucleo board to test a proof of concept clock recovery solution. I am using the CRS external GPIO sync pin with a 1kHz refclk to synchronise the HSI48, and output the synchronised clock on MCO1. The issue I am having...

STM32H750 with Dual-Flash , can not work after enable the TimeOutActivation in memorymapped mode.

If i enable the TimeOutActivation in the memorymappedmode then device hangup randomly. if i disable the TimeOutActivation then it work normally.The code snippet as below :QSPI_EnableMemoryMappedMode(QSPI_HandleTypeDef *hqspi)  s_command.InstructionMo...

STM32G031J6 stuck in non programmable mode

Hi there, during the development I have accidently flashed (via ST-LINKv2 SWD) two chips (stm32g031j6) with program which sets PA13 as INPUT, PC14 PWM OUTPUT and initiated hardware SPI (pins PA12, PA11, PA1). After flashing this program, chip does no...
