I am interfacing a 5V PWM signal with an STM32F030K6T6 MCU using PB0. According to the datasheet this pin is 5V Tolerant. In the past, regardless of a pin's "tolerance" to 5V I have always used a level shifter to change this 5V signal to a 3.3V sig...
I am using uart on STM32L07 to simulate 1-wire for operating ds28e22. 1-bit timing is more than 1us and less than 2us. When I set baudrate at 666666 which meant 1 bit timing was 1.5us, I found the rising edge was too slow (more than 1 us). So I want ...
HiCan you tell me how I can calculate a value for ARR for timer 2(32bit timer) and timer3(16bit timer)I am using STM32F407 APB1 timer clock is 12MHz prescaler is 6
Hello,I have a STM32G431KB on a custom PCB and got the CAN bus to work. The only problem I have is that the TX FIFO is always filling up and the bus stops after 127 errors.The workaround I have is to abort the TX request./* Add message to Tx FIFO */ ...
I'm developing a custom board with an STM32U5 MCU and a MX25UM51245 NOR flash memory. I'm building upon this example, which works flawlessly, but I don't want to format the memory every time the code runs. To achieve this, I disabled the Driver calls...
Hello everbody,I'm using the STM32L4KC Nucleo board. Accidentially I discovered something that I cannot understand so far.I have a small application that is reading sensor data on I2C. So far everything works. When I cause by purpose some interrupts ...
Hello, I have been trying to implement IAP in my device. But my code gets stuck in "UART_WaitOnFlagUntilTimeout". For once I was able to transfer the binary file of the new user application but later whenever I am trying to send the binary file it is...
I have an optimized SPI Slave DMA setup which is driven by the chip select interrupt. It looks something like: int main(void) { // Initialize SPI SLAVE, SPI_DATASIZE_8BIT, SPI_DIRECTION_2LINES HAL_SPI_TransmitReceive_DMA(hspi, (uint8_t *)&spi...
hi allI have a weird operation on the I2C2 in STM32H743ZI cpui am sending 2 bytes to a I2c slave PCA9536DP, address= 0x41the operation works and the slave IC did toggle the outputs BUTat the end of the I2C2 transfer, the TC bit did not set even thou...
We need support with the interrupt vector mapping for the STM32L010R8 SoC, specifically from the Boot area to the Application area (Flash/SRAM). We are currently developing a custom boot loader for the STM32L010R8 series and are not using the ROM-bas...
