OK, gang, here's whats up: I have over the past year or so been playing around with a couple of SerLCD modules (+ 2x16 displays). After a couple of speedbumps, most notably that only HSEROUT seems to work with a 16F628, I was at the point of having it all happy and nice.
Note that I said "was". Right at the moment things are screwy, and to tell you the truth I've tried swapping/changing so many parts of the puzzle over the last few days I'm not completely sure where I am!
How about this for a specific: has anybody seen behavior where a module comes up OK (the splash screen shows), then the display stays blank until you bring a finger near the wire leading to RX, at which point semi-random characters appear? Yeah, there is a 7805 with a decoupling cap behind everything. Yeah, IC-Prog works fine otherwise via a PG2 programmer.
What other LCD show-stoppers have people found, preferably with solutions attached?!
thanks,
Patrick
