Hello,
I want to use UART + DMA to receive unknown length packet. So I tried to use IDLE interrupt to monitor the end of the packet. On the other hand, I use a PC tools to send several bytes data and delay a while, send several bytes to generate the IDLE line condition. But unfortunately, I cannot receive IDLE interrupt. Could anyone can give some advise to how to generate the IDLE interrupt and deal with my case. The MCU I used is STM32L152. Thanks.
