Hi, I ordered up an AXE033 LCD module and built it last night. Great little kit (although they didn't include a jumper for CLK, and it'd even greater if it was backlit). I also added the 'clock' just for completeness.
Now after tinkering and doing the "hello world" sort of thing I have a few questions. I've read and re-read the datasheet, and had a search about here but can't find what I'm looking for, so I hope one of you can help?
[assume I'm using serial mode not i2c]
1) I'm after a full list of 'Control Commands'. I found the 'scroll' ones ('254,24' for left, '254,28' for right), but guess there might be more to play with?
2) I notice that if I display a pre-saved 16 char message and scroll it using the 254,24 command, the message scrolls off screen leftwards for quite a while until it returns on the right. So I assume that there is a max length for a line, with only 16 chars being displayed. Anyone know how long this is?
3) Is there NO way to get the time /date on the top line? And is there a way to display just the time and not the date?
4) Are custom characters at all possible with the AXE033, or would I have to drive an LCD directly to achieve this?
5) How would I display one of the special characters shown in Appendix B of the datasheet? e.g. the ohms symbol.
Right that'll do, thanks a lot
