Hi @rodi66 What makes you think the source for the unexpected interrupt is TXE ? is it because TXE flag is 1 in ISR ?By the way, at end of transmission, TXE will stay at 1 and cannot be cleared in ICR, but this should not trigger USART2 interrupt.Wha...
Hello@_AK As mentioned by @gbm , for completion of a DMA transmission, initiated by HAL_UART_Transmit_DMA(), both interrupts of DMA channel and USART/UART instance, need to be enabled.- DMA interrupt will occur once all data have been handled by DMA ...
@Andrew Neil, @Louie88 I checked with latest CUBEMX 6.13.0, starting a brand new project from "Acces to BAORD Selector", then picked up theThen, i choose to initialize all peripherals to their default configs.And I could check that PA9/PA10, are prop...
Hi @Louie88 Are you using the Virtual COM port on ST-Link connection ?In this case, I'm not sure you are using the right PIN for RX (PB7).Could you try PA10 instead ?In DK manuals and schematics, I think PA9/PA10 are mentioned for VCP connection on t...
