#105319 - Polled; Interrupt Responding to: ???'s previous message |
Jon Ledbetter said:
I still want to include a few more sample programs to show the difference between polled and interrupt driven I/O and one with a ring buffer as Sasha suggested. But I've stumped myself. Keil has a fine example of ring-buffered interrupt-driven serial IO. Is there such thing as polled transmit? Of course there is! Because you're really not polling to see if there is something to send. You just send it. You poll to see when the transmitter is ready for the next byte! Then... Can you have interrupt driven transmit with only a one byte buffer? Sure - but it probably largely defeats the object! |
