Any idea's on squelch circuit? I was thinking about using an LM358 opamp putting the RSSI and a threshold into one amp then the output of that (maybe thru a divider) to the input of the other amp alongside data to get a squelched output?
I think MELabs should modify their code for the serin timeout and supply a timeout feature that will timeout if the qualifier isn't met within the timeout period I realise this would be more difficult - but I've spent hours fluffing around on what should be such a simple project - monitoring an RF receiver and counting down the time - i can't exit from the serin cos the static noise on the line resets the timer in the serin command, i can't use Darryl's wonderful interupt file cos it chews up all my variables, i can use an asm interupt cos I'm not really advanced enough to figure it out. Hopefully the squelch will work albeit with what probably is a significant reduction in range.
I do like Mister_e's concept of looking at a USART - I might have a quick look in2 that before I build my squelch
