I have written a code to receive UART data in DMA interrupt mode using circular buffer and configured timer 6 and timer 7 for doing other tasks in the same code. The problem I am facing is that I am not getting UART data and neither timer interrupts ...
I'm working with the STM32F446-microcontroller and once in a while after power-up the microcontroller is unable to drive pin PA0 high or low and I also suspect that it can't drive PA8, configured as an I2C-clock, either when this problem occurs. Ther...
Hi,I am using an STM32H753 connected to a raspberry PI via SPI. The STM32 is connected as slave. With CubeMX I configured the STM32 to be an SPI Slave with both DMAs configured as circular. I am having a struct with live data (refreshed every 10ms) a...
actually I'm using stm32F446RE, I'm using hal library just to detect external interrupt from PA1 pin but it doesn't work, and if I put the interrupt from PA0 pin, it works fine?/* USER CODE BEGIN 0 */ void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ c...
Hi ! I am receiving data from two devices and want to transmit it using usb. I am able to send using usb when receiving (to a circular buffer) only from one at a time but when I receive from both, it doesnt work (a lot of data is lost and I cannot d...
Using this on our board and have noticed it slowing down with increased use, just wanted to know if its potentially the magnetic field but I can't find the MEF for this board
Hi,I am currently working on a synchronous buck converter (24 VDC in and 1-15 VDC, 1-15A out) for which I used the HRTIM of the STM32G474 in combination with the FMAC as a control loop:I mainly followed AN5496 and AN5305 to get my converter up and ru...
Hello, I have the project in which I need the flash the stm32L0 with uart using the system bootloader. I have settted required option bytes. I make the boot 0 pin high and the sytem is getting into the bootloader mode. I attach the usb to uart conver...
I use FSMC in STM32F407 to access external SRAM IS62WV51216. I read RM0090 and AN2784, gives me two fomulatSU means here is the timing graphhere is write timing graphwhy WE have two falling edges on the leftwhat dose tSU tV mean,where is it in the t...
