stryd_one Posted November 15, 2008 Report Share Posted November 15, 2008 I guess this would be a wiring error. The OPL and LCD share a data buss, and perhaps they are talking at the same time.I would first check all connections against the schematics with a multimeter. I'd also consider soldering the components into the PCB properly, rather than leaving hem floating like that - it leaves room for short circuits. Similarly, it's worth investing in connectors for the cables, rather than soldering them onto the jumpers. Quote Link to comment Share on other sites More sharing options...

TK. Posted November 15, 2008 Report Share Posted November 15, 2008 Yes, seems to be a connection issue. "READY." indicates, that you haven't uploaded an application yet, MIOS itself only writes READY a single time, thereafter no LCD transfer will take place anymore. But you reported, that you notice still changes (more black bars) - therefore a typical connection issueBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
