Hi, Is there an example of an open bootloader for the STM32F4xx series? I've attempted to adapt an open bootloader example from the STM32C0xx series to create an example for the STM32F411, but I'm encountering numerous errors due to differences in th...

Hi, I have an STM32F411RE master device connected to a slave STM32F411RE device via a UART connection. I need to update the firmware of the slave device using a UART bootloader. How can I initiate the bootloader mode on the slave device, and what pro...

Hello, I'm using an STM32F411RE MCU to control a DC motor driver, and I'm encountering an issue. Whenever I program the microcontroller using the STM32CubeIDE software, the motor starts operating.This occurs even when I connect the electronic board t...

Hello, I have developed two codes to test the I2C communication between a master device (STM32F411RE) and a slave device (also STM32F411RE) in DMA mode. The expected result is as follows: whenever there is a rising or falling edge interruption on GPI...

Hello,I have developed a code in FreeRTOS mode that contains two main tasks. The first one check if I have received an RX buffer on the I2C bus, and the second one manage the data that has been received.However, after receiving the first buffer, I am...
