STM32L072 SysTick_Handler is never triggered

The IRQ is setup as follow:__weak HAL_StatusTypeDef HAL_InitTick(uint32_t TickPriority){ /*Configure the SysTick to have interrupt in 1ms time basis*/ HAL_SYSTICK_Config(SystemCoreClock/1000U); /*Configure the SysTick IRQ priority */ HAL_NVIC_SetPrio...

How to setup G431 DMA for peripheral to memory single transfer

Hello,I have a G431 working with TIM8_CH1 and TIM8_CH3 generating DMA interrupts for a peripheral to memory transfer. I am not getting the correct number of transfers on TIM8_CH1 which is a capture compare triggered by an external input pin. TIM8_CH3...

Issue when configuring PA0 as input on STM32F030K6T6

Hello,On a pcb on which there is the STM32F030K6T6, I am facing a strange issue.First, the context is that I am using different timers, interruptions, DMA, UART, analog inputs and digital outputs (PWM, ON/OFF signals).2 of the i/o's are concerned by ...

RS485 Receive Buffer Corruption

I have two device on the Rs485 line, one of them transmit the data, another receiving the data.Transmitter, transmit rs485TxBuffer, it is include `uint8_t rs485TxBuffer[2]={0xAA,0xBB}`.I expect the receiver fill the receive buffer with these data. Bu...

STM32L011K4 watchdog does not always reset the device

I am using STM32L011K4 MCU and it says on errata that:"The IWDG must be configured so that the counter starts counting down and generates a reset when the end of count value is reached. In some cases, the configuration does not work, the IWDG remains...

Why the uart OverRun flag is set when receiving only one byte in a frame?

Hi!Using a STM32F1 uart peripheral waiting for a 22bytes frame but sometimes I get an overrun error right after the reception of the first byte.Handling this in an interrupt mode, I expect 1 byte at a time and re-enabling the interrupt after each rec...
