Hello,I have a NUCLEO-F446RE board, lots of homemade boards with little MCUs (STM32G030F6, STM32F103C6, ...), some blue pills and programmers. Only the first ones I bought has an original chip. The other blue pills and programmers, the vendor lies an...
I used PA11 and PA12 as standard GPIO in STM32U595ZJT6Q and system frequency is 4MHz. Config PA11 and PA12 to PP output mode ,no pull up.Don't set this gpios to high, the mini system current is 3mA,but set this gpios to high, the current is 22mA.Test...
Hi, I'm using an STM32F401RE board for a class(programming using MacOS). Right now, I'm using VSCode and make to edit and compile my code, then using stlink to flash it. All I'm trying to do is print hello world to the tty.usbmodem* screen in the /de...
hi, I was looking for HAL -library for stm32334r8 MCU but i dont see anything about HRTIM in the avilable HALY library. where can I find HAL instructions documentation for HRTIM ?
Hi,I'm trying to write RGB data directly to an 8+8+8 bit i8080 screen using the DMA2D and FSMC peripherals on a STM32U575 Nucleo board. As a test, I set up the FSMC and manually sent data one uint8_t byte at a time - this works fine. However, I'd lik...
I am using an STM32L562VET6Q. My device contains both a (custom) bootloader and an application. The bootloader jumps into the application by reading the address of the Reset_Handler from the application's ISR vector then branching to this address. ...
Hi!I am building PCB around STM32F469ZET6.Now LSE and HSE crystals and accompanying capacitors need to be chosen.AN2867 says capacitors values should be CL1 = CL2 = 2 x (Cl - Cs)Cl – crystal’s load capacitanceCs – stray capacitance of oscillator circ...
Board: Riverdi display with STM32H757XIH6 MCU; using TouchGFX and FreeRTOSI think I know how BASEPRI register works and how it is used in FreeRTOS. What I do not know is where is the value of BASEPRI register set at the beginning of the program. I no...
Hello, ST experts STM32F417 is used on custom hardware design. And everything is OK except SD card. At first SD card works well. f_write takes about several milliseconds. But when the free space of SD card(San Disk Ultra 64GB) is less then e.g. 10GB,...
Hi I am using STM32F401RE controller but on my PCB, so here can I use the pins allocated for its programming/code dumping also as normal GPIO's. Any precautions which needs to be taken care of?
