UART RX interrupt example #1

Closed homewsn closed 2 years ago

homewsn commented 2 years ago

First, thanks for giving the opportunity to review the ASR6601 SDK.

I have a specific question about the operation of the UART in the mode of receiving bytes by interrupt. Unfortunately, I did not find such an example. The test project I implemented generally works, but for some reason the RX_DONE flag of the MIS register is not set when the interrupt handler is called after receiving a byte, although IMSC RX_DONE is 1 and an interrupt occurs.

Sorry, it's working fine. Just the debugger reads the UART data register and clears the RX_DONE flag in front of me :)

But, by the way, are you sure that the UART_CR_UART_MODE macro and the subsequent ones in this group are correct? It seems the correct value should be 0x300 etc.

Yes, you are right. It should be 0x300. Thanks very much. For the uart rx interrupts, you can take a look at the ota/dongle example.

Ok, thanks.
