I'm using UART to send message. To prevent data race, I'd like to first disable then enable transmit complete interrupt when trying sending more data. But enabling transmit complete interrupt generates an unexpect interrupt. static volatile bool g_s...

Thanks for the reply. -fstack-usage is already checked by default in STM32CubeIDE. From my understanding, gcc -fstack-usage reports the stack usage of single functions, not including the stack used by subfunction calls. STM32CubeIDE may have a plugin...

Thanks for the reply. I've done an experiment to read the USART's registers' valuesAt the beginning of USART1_IRQHandler, SR is 0xc0 (TC, TXE=1, others 0), CR1 is 0x204c (RE, TE, TCIE, UE=1, others 0)At the beginning of HAL_UART_TxCpltCallback, SR re...
