I would like to know if the STM32F407G-DISC1 development board has a dedicated VBAT pin for powering the internal RTC, allowing it to maintain time even when the board is not connected to power. If there is no VBAT pin on the development board, does ...
Hello, I recently got my hands on a Nucleo-U031R8 with a cortex-M0+ processor. My goal is to to reach 52 nA (using usb cable) in shutdown mode, but as of now the lowest i could go is 490 nA. HAL_SuspendTick(); HAL_PWR_EnterSHUTDOWNMode(); The code ...
Dear all,I'm unable to connect via SWD to my STM32F103C8T6. What ever I try I get no target found with STM32CubeProgrammer or ST-LINK Utility (I have tried all combinations at slow and high speeds). - device is virgin- BOOT0 is low- NRST unconnected ...
Hi everyone, I am using STM32H747I-DISCO. I want to use ST-LINK V3E port for UART communication port. I am configuring USART1 and using the HAL_UART_TRANSMIT function. After download the code I close the ST-Link connection and using a serial termina...
Hello I think we can control the reset and boot0 pin of F407 externally through a different board STM32H745 disco. I want to put the F407 in boot mode and send data to program the F405 through UART. Please confirm Thanks & Regards, Anuj
Hello, I have created a custom PCB based on STM32U545RET6Q and I am getting crazy to do it work. I have a random errors and I can't solve any of them becaouse each time the hardfaluts are different. I started to work with the EVAL board MB-1841 (STM3...
Hi, I have a buffer with 65000 values in 16 bits from the ADC read that I need to provide to my computer running a python code.Any suggestion how can I handle this in both sides?I'm trying to use this function but I'm getting weird data when I'm list...
I encountered an issue where an error occurs when only the image data is moved to NOR Flash in the linker. I have already verified that the NOR Flash works correctly in a separate project by toggling the LEDs.In my current TouchGFX project, I enabled...
Hi,Although I'm quite familiar with Arduino and Teensy MCU's, I'm just getting started with STM32. I followed this 'getting started' video to upload an Arduino bootloader to my STM32F103C5T6 'blue pill' module, using an ST_LINK module.Before uploadi...
Hi All,I've been using my ST-LinkV3mini for a few weeks now quite happily, until two days ago when it just stopped talking to my M3 MacBook Air (MacOS 15.0.1). I'm fairly sure I know what's happening, when I try to communicate between the laptop and ...
