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...
I am developing my own driver for a STM32 MCU, however I always get the same error when I try to compile the code. Here is the entire code from all the files I developed.There are always 8 errors, saying that pGPIOA, pGPIOB, pGPIOC, pGPIOD, pGPIOE , ...
I'm using a B-U585I-IOT02A discovery kit that that has the STM32U5 MCU. I'm looking to evaluate if the STM32U5 MCU can run an FFT in real time and how to evaluate the performace of the STM32U5 MCU running FFT's. Are there any tools to help me do that...
I am using L476RG ST board, and I recently purchased a GM95 QR scanner that supports standard TTL-232 serial communication. UART2 is configured to work with my PC using PuTTY as an interface, but how do I receive the data from the QR scanner and disp...
Hi.Is it possible to reconfigure one or some regions MPU without fully disabling MPU?I need configure for example ITCM memory for RW access when load code and set to RO mode after code copied completed.Code copied from SDRAM to ITCM, so MPU needed fo...
