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 ...
Hello, this will be a rather advanced problem that I'll be presenting so please bear with me until the end.I'm currently working on I2C communication, with a configuration where I have a controller that initialize 4 STM32g0 on custom PCBs.TL;DR : I w...
Dear to All,I have a boar with STM32G030J6 and I want use the TIM3 as PWM output (on PB0->TIM3_CH3) using DMA1 channel 3 to transfer data from RAM memory to TIM3_CCR3 register. The problem is that DMA never trigger the interrupt!Here the code:// Setu...
