Hi, i am trying to call timer interrupt handler using registers and the following is my code, but the problem is that the function is being not called, I see no output in the oscilloscope or live expression. First my DAC value is still 0, the counter...
Resolved! How to read GPIO direction using HAL?
Hello world,I'm developing a FW for STM32F107VCT6 which can change GPIO direction programmatically: there is a terminal command which can switch individually 7 pins* mapped on different ports between GPIO_MODE_OUTPUT_PP \ GPIO_MODE_INPUT.I'm wonderin...

All data received in normal mode is 0, but some correct data can be received in debug mode？ cubemx configurations are as follows：Part of the code is as follows:uint8_t pData[128] = {0x00}; HAL_SPI_Receive_DMA(&hspi1,pData,128); while(HAL_SPI_GetStat...
Resolved! How to accurately determine whether comparator interrupt was generated by rising or falling in the interrupt routine
I use comparator(COMP7) on STM32F303VB as・Non-inverting input: PC1 (ADC)・Inverted input: DAC2 output・Comparator interrupt: rising/falling edge triggerI checked the COMP7OUT bit, but it seems that this bit is "comparator output at the time the bit is ...
How to enable peripherals in LRWAN module on stm32l072
Hi all,I have recently started working on stm32l072 LRWAN module of stm. I was able to build and run the code as it and was also able to send data to the gateway. My next task is to interface some sensor the the controller and send the sensor data to...
Resolved! UART_DMA CODE Generates for STM32 CubeMx
Hi @RomainR. sir,As i already posted a query regarding UART DMA using STM32G030K6T6 controller, you have corrected my code it worked well. when i generated a new project and i followed the step to have provided me but it doesn't work it get stuck in...
[STM32H757] Issue with the FW running after the compiler optimization is turned on
We are developing STM32H757 Firmware using STM32CubeIDE (V 1.10.1, GNU Tools for STM32 (10.3-2021.10)). We have encapsulated an SPI read function based on ST's BSP. When tested on CM7 with optimization options turned off (-O0), the function can run n...
