Hi Melanie...
I am having a little problem with your program.
I loaded it into the 16f628a, and it appears the characters are getting to the rx port, but no echo's or messages....
Hi...
Sorry it's taken me so long to verify this... just so much work and so little time.
Worked straight away witha 16F628A out of the box... but... then I tried it on a normal 16F628 (just a random selection from stock)... and I had comms errors!... not all the keys on the keyboard would echo, and those that did were wrong.
So I recompiled for a 4MHz xtal (Resonator actually using XT_OSC), added the bits... and tried the chip that was giving me problems... whoo-hoo... away it ran without errors.
This just proves that Async comms even at 300 Baud are not always reliable on internal oscillator. The variances between individual chips are just too great.
I shall post this on the forum.
Melanie
