STM32 MCUs Embedded software

STM32F4 as I2C Slave. Why “void I2C1_ER_IRQHandler(void)�? is executed after “HAL_I2C_Slave_Transmit_DMA�??

I am using I2C bus as SLAVE mode in a STM32F411RE. The master is an arduino board.The configuration is working well because I see thougth master serial (arduino) and STstudio (STM32F411) that all the frames are OK and thrue oscilloscope.I noticed tha...

Is by any chance the STM32 factory bootloader available? I'm not looking to modify it, but just to use it as a reference.

I am a newbie to both FreeRTOS and STM32. I want to know how exactly callback function HAL_UART_TxCpltCallback for HAL_UART_Transmit_IT works ? Can we edit that that callback function for our convenience ?

This has nothing to do with my program, can I change this? __weak void HAL_UART_TxCpltCallback(UART_HandleTypeDef *huart) { /* Prevent unused argument(s) compilation warning */ UNUSED(huart); /* NOTE: This function Should not be modified, when ...
