#126574 - Delay. Responding to: ???'s previous message |
If you (sorry - I know this is asking a lot) read about the UART in "the bible" you will see that as long as you unload a character from SBUF within 90% of the reception of the next, you are fine.
I think that was meant by "delay". Since you know the baud rate of the UART, you also know exactly how long you may wait before reading SBUF, since the last byte will still be available while the start bit and bits 1-8 of the next byte are received by the UART. If your baud rate is sufficiently low (say, 9600 bps), receiving one byte will literally take an eternity (almost one millisecond) for the uC. |
