I made a project with stm32h7 board, and use pemicro multlink to debug it under keil. I found it keep in systick handler pending but no active.I checked systick module register as:the counter is changed.and then I checked SCB releate registers asand ...
Hello STM32G0B1 For some obscure reason, sometimes the systick handler function is not called anymore.I mean, it works for some time then it does not work anymore. It looks like it is more likely to happen when I'm debugging but I have no factual inf...
Hi Everyone,I use STM32L083 MCU. My code has two sections which are bootloader code and main code. Bootloader Code Start Address : 0x0800000Main Code Start Address : 0x08006400I implemented low power mode in my main code and used "HAL_PWR_...
I have a custom board that I am getting ready to program that is using the STM32U575. I am a little confused about the clock configuration. My board has an external 32768 crystal. I am not sure I have the MX program clock configuration correct. I wan...
hi，for our project，we used firmware package was STM32CubeG4 Firmware Package V1.6.0 / 05-June-2024.IDE: MDK 5.39MCU: STM32G473MET6 EEPROM: 24LC256we already check the page write opreation, ensure the boundaries and size of each write (less than or eq...
Some parts of my application are driven by the SysTick timer, and I got into the practice of adding `HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_STOPENTRY_WFI)` while polling a flag, knowing that the SysTick interrupt will wake the microcontrolle...
Hello guys !I am new at the embedded systems and I am trying figure it out ! I am using STM32F446VET7.I connected my buzzer to an GPIO pin(PB12) which has no pwm speciliaties.But my buzzer is not working when I connected to the DC signal source like ...
Hello, I am using STM32H7 dual core series. Currently I am planning to enable FreeRTOS in M4 core and let M7 core run in regular fashion. As FreeRTOS uses SysTick, I have given M4 core on of the controller timer. Is there any need to also give M7 cor...
Hello,I usually make a code based on the timer callback function to handle multiple tasks.However, I don't know why functions like printf in the systick callback function don't work at all if the flag switching is in the same function.It works If I p...
Hi,I have scoured the web for a solution to this problem, but I cannot find one, typically the replies are the same, but the solution is never found. I have tried every other solution you will find.I was playing around with the cube mx trying to solv...
