Resolved! [SOLVED] [STM32H503] SPI1 does not send anything
Good day, everyone.I'm trying to launch SPI1 under Arduino IDE. The transmission didn't work and I switched to direct control of the registers. The code used is below: #include <Arduino.h> #include <SPI.h> void setup() { SPI.begin(); Serial1.beg...
STM32U5 bootloader hardfault error
Hello All,I am new to STM32 controllers and am working on flashing my application binary using Xmodem (bootloader) on the STM32U5A5VJ controller. The controller has secure and non-secure memory regions: Secure region: 0x0C000000 to 0x0C3FFFFF Non...
LwIP Ethernet in STM32H7 working in STM32CubeIDE but not in IAR
Hi, I'm using STM32H745ZI implemented ethernet with Lwip it's working fine STM32CubeIDE(ver-1.90.0) but not in IAR(ver-9.30.1) like any changes that I need to do in .icf file of IAR because it's working fine Cube IDE
Monitoring Voltage Differential with ADC for up to +-30V
Hello,I need to build an STM32 based solution which will monitor the voltage differential between a .47Ohm resistor on a separate power amp circuit. ( measure the amp's bias ) Both circuits will share a ground.The voltage read across the resistor...

I have a small working touchGFX project with freertos app on a stm32F746-disco. I want to write a few variables to flash so I am trying to call write/read in StartDefaultTask, but I get a Hard Fault when I go to Lock the Flash. I have tried a few ...
Resolved! STM32F103 UART and USART clock configuration
I am working on a project that uses STM32F103 and STM32G4 as MCUs. They need to communicate between each other using UART. I am trying to configure STM32F103 UART clocks to match the STM32G4's clocks but I have not been able to figure out where to do...
STMF407G-DISC1 LED are not changing in project, despite value changing correctly
Hello,I made simpler project, where led is switched on button to represent binary, and there it works. Two RNG values (0-7 and 8-15) are generated and with button press switches between LED binary representation of two RNG values.I made the same thin...
