An issue with event flag

Hello,I have an issue with event flag I am setting this flag inside ISR of GPIO pin interrupt and there is a task wait for this flag but even if the interrupt is come and set the event flag the task still in blocking mode this my code : void MXT_vidT...

Why can't I clear the SRAM_PEF bit?

Hi there,I'm using the chip STM32G431CBY3 and here is a strange thing. After I start the TIM15 in interrupt mode and every time the interrupt enters, the NMI_Handler enters at the same time, by checking the register, I found that SRAM_PEF bit is set ...

I am using crystal resonator part ABC2-8.000MHZ-4-T to supply HSE clock of MC STM32F303ZET6. 1) Is this Feedback resistor(Rf) available inbuilt in MCU? (or) I have to add it ? 2) Can you suggest values of CL1 & CL2? 3) Can you suggest value of Rext?

STM32H7A3 HAL_FLASH_Program() data and address alignment

Hello There,I'm working on an IAP application based on STM32H7A3 and have a query related to code alignment.Correct me if I'm wrong, as per my understanding HAL_FLASH_Program() in H7A3 writes a flash word (i,e., 16 Bytes) at a time. If so, then it mu...

Change STM32F103 to STM32F303

Hi ST experts,According to AN4228, we can migrate the MCU from F103 to F303 with minor changes development needed. Just wanted to understand more on the pin assignment between the parts, I take an example of STM32F103ZET6 vs STM32F303ZET6 with same p...
