STM32CubeMX basics: 10.11 STM32Cube HAL labs UART - UART DMA

[@Lucascane]

There is a mistake here. If you don't enable "USART1 global interrupt", uart tx will not work after 1 cycle. Because this will ensure the USART communication by checking the flag, as the set of the ready flag is managed inside HAL_UART_IRQHandler() by the UART_EndTransmit_IT(). Otherwise gstate will stay busy all the time.

It is worth to add that HAL_UART_TxCpltCallback will not be called unless you enable UART interrupts.

hilarious seeing an ST employee using IAR EWARM also hilarious how little that software has changed over the years....

Thanks! It helped me a lot :)

Please get some guy who speaks simple english

[@eduardosantana1793]

Please be polite, STM and their employees made a lot of effort to training us, it's possible to understand when he speaks, I'd like to suggest you to take another course if you are not understanding the lessons. Thank you STM to help us to improve our knowledge.
