I have a STM32F7xx MCU connected to a Winbond W25Q01. The datasheet says the chip will run up to 133MHz. If I set the MCU clock to 108MHz and the quadspi clock prescaler to 0 so that they are running at the same frequency, the chip initializes and c...
Hello,I have 15ADC channel , I read the ADC channel when some external event is gnerated ,for eg when the battery is connected to one ADC channel then the interrupt gets generated then I have to read that channel , so in ADC interrupt handler I have ...
Timer2 uses timer input capture mode. The input is coming from a function generator and is a block signal. It triggers the capture callback on falling edge. On the capture Callback interrupt I read in the capture compare register of Timer2 and I chan...
I have two boards, one with STM32F303 with CAN 2.0 and a new board (same electronic, only MCU is different) with STM32G474. Software is identical too, except for the CAN/FDCAN. So I had to migrate the software from CAN 2.0 to FDCAN Classic in order t...
Maybe I am naive, but last year this code worked and now it doesn't...I have this small lab experience where I manually implement PWM to control the brightness of the LEDs on a Nucleo F767ZI board. My idea was: let's ensure that the switching of the ...
STM32F746-DiscoCapacitive Touch Panel FT5336STM32CubeIDE, Windows 10CMSIS-onlyI'm developing my first I2C driver for STM32F746 using CMSIS-only, and I've decided it would be great to test my I2C skills on built-in capacitive touch panel FT5336. I use...
Can we be sure that there will never be a new revision for this chip ?
Hi there,On some MCUs, I've noticed that the second call to HAL_I2C_Slave_Transmit_IT hangs forever.An example I have is on an STM32G030K6 (which doesn't seem to happen on a STM32G474RE).I have set all pins to fast to ensure that's not the issue eith...
Hello,I want to control a timer period with a variable. The variable value is correct because I monitored it in the watch window. But the variable was not working in the timer settings. Because when I write a digit in there, it works. Is there any su...
I have been using HAL_SPI_DMAStop to abort my SPI transactions and usually it works, but every once in a while I notice my SPI bus gets all jammed up or whatever and stops working. I noticed that the HAL_SPI_DMAStop function is not returning HAL_OK.S...
