Hello.

I have a question about Idle line interrupt on STM32 (specifically STM32F0x8). When does this interrupt triggers, only on reception or both reception and transmission of package? #stm32-usart-idle-dma

Find that.

The

answer

is on the

first page of the

section

 ''USART Interrupts''. Idle line interrupt works only for reception, and for transmission there is Transmission complete interrupt.
