#129851 - I hope Russell did not lead you down the garden pa Responding to: ???'s previous message |
Using interrupts gets a little more complex. Usually the interrupt would read the data to be sent from a circular buffer of just a simple buffer. Your main code would put the required data in the buffer and signal the interrupt code to send it.
I hope Russell did not lead you down the garden path yes "Using interrupts gets a little more complex", but only about 10%, however it is ~47000 times more effective. Polled serial has been the bane of many projects. It works like a charm for the serial and kills everything else. if you are using polled serial change it immediately Erik PS I might use polled serial for a quick hardware debug, but NEVER for "working code" |
