Resolved! Can't communicate with another device via UART
I've been fighting this problem for some time. I have a simple custom made board based on STM32G05. I'm utilizing 2 UARTs. One of them I use just for serial port debug. Takes keyboard input (but don't use it) and print out data for debugging. The ...
Resolved! STM32 Bus Matrix behavior and arbitration mechanism
Hi,I'm trying to learn DMA in depth, but I'm confused at some points. It's about Bus Matrix and Arbitration mechanism. In STM32F446RE, there are 2 DMA controller and each one has 1 peripheral bus and 1 memory bus. Question is not about memory bus of ...

QSPI STRANGE BEHAVIOR WHEN AUTOPOLLING
I am trying to autopoll wip and wel bit from status register (0x05) in a flash memory when I perfrom a erase process.The first autopolling operation is correctly, however, the second time that qspi try to autpoll the bits, this does not release CS, a...
Resolved! STM32H743AII6 Wrong temperature value from internal temperature sensor
Hi to everyone,I have 2 batches of a board (let's call NEW and OLD version) where internal temperature sensor of STM32H743AII6 (connected to ADC3 channel18) is used. Differences between batches are related with I/O pins (used MCO1 instead of MCO2 a...
Setup for CAN-FD communication with NUCLEO-H7A3ZI-Q
Hello good day!I want to setup a CAN-FD message sending simulation with H7A3ZI-Q (one or two message ids). But i do not exactly know how to assemble the HW and what i need (For STM side). I know this board is capable of the CAN-FD but it needs a tran...
How to read values from a GPIO_EXTI pin?
I want to read values from ultrasonic sensor for my project. I use STM32l452RC controller. I am able to do that if I map that pin as GPIO_Input and by using the HAL command HAL_GPIO_Read_pin.But I want to map the input of the ultrasonic sensors as in...
Hello, I am using STM32f746g discovery board and with appwizard generating the ui for the board when i flash the generated code i am not getting the desired output.?
In debug it is going into the hardfault handler and the code is not starting from the main it is starting from__STATIC_FORCEINLINE void __DSB(void){ __ASM volatile ("dsb 0xF":::"memory");}and when i step over from here it is going to main()after that...
