HiI just put together my USB LCD card. It looks like the display is working but with a few hick ups.The software is configured to look like thisBut the lcd display shows this:It looks like it won`t display odd numbers and substitutes it with the one below. (1=0, 2=2, 3=2)The same thing happens with letters (b=b, c=b, d=d, e=d)I got the latest version of IOClcd (1.04) and is using a HD44780 LCD DisplayAnybody know what is causing this?Regards Jarle

I'm using HD44780 displays for my autopilot module (I'm not using LCD board from Opencockpits but I made my own interface) and I noticed strange display behaviour if data to the display are sent with a too high speed or delays between a command and another are not respected.I suppose guys at Opencockpits developed LCD software according with the datasheet of the HD44780 but, you know, there are a lot of displays "HD44780 compatible" but they are not a true HD44780 so it may be possible that your display has a different tolerance in timing if compared with a true HD44780.Have you tried to post also in the Opencockpits forum?Regards,Bob

Check the line correspondig to D0 (bit 0), it is possible not has been connected right !
