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 ...
Dear all, I am relatively new to STM 32 ADC setup. I am using STM32 L0 seriesI want to read data from one ADC channel for 5 minutes, 15 minutes and 8 hours.Duration will be set by user according to needs. I Don't know where to start and is it eve...
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...
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...
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...
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...
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...
hello everyone, I have a small mistake when I want to make something like the photo, it give me error what is the problem, If anyone help me, It is very good for me, thanks.
Hi I would like to know if I can still get the interrupt updates of a timer but disable the call to the callback HAL_TIM_PeriodElapsedCallback.
I tried to get the minium delay between output state but I am limited by the GPIO toggling speed, I even tried PWM generation and there is an option on GPIO settings -> Maximum output speed but I can't change it by clicking on it.Does anybody has an ...
