Hi Juan

BTW - are you using a MAX232 between the PIC and your display? You do know that your display will not operate at 5v rs232?

The baud rate on the GL displays are handled through the command set. $FE $39 $xx sets the baud rate. The default baud rate is 19200. I had initial problems with the displays baud rate 19200, it would also intermittenly drop characters, and I had to drop the baud rate down to 9600. Since the project had some tight deadlines, I did not spend the time to find out why the 19220 was a problem.

There were two setup jumpers on the board to setup the 4 pin header as I2C or RS232C. There were 4 solder pads that sets the RS232 port is +/- 12 or TTL level. The photo they show in their documentation does not reflect the revision I had, so I had to make a guess as to the correct pads. There are actually another 1/2 dozen solder pads through the board, so I did take a guess that the pads closest to the MAX232 would be the ones.

I am adding another point to the "why I hate MO displays" list. After burning 2 late nites trying to resolve an erratic display error (after a period of time, the display receives and displays text in slow motion), it turned out to be an occurence of how their stupid backlight timeout operates.

Anyways, now that this part of the project is complete, I will put the MO experience behind me, and I am ordering up several new displays from Noritake. Just as an aside - One of my earlier projects used a Noritake display. During yet another critical weekend I accidently reversed the polarity on my power supply and fried the Noritake display! I contacted the Noritake rep, and without a blink - they couriered a free replacement to the site where the display was needed. We installed and we got our demonstration working on-site. In my books, these reps went above and beyond helping out a developer.

I tried the MO display only because the power consumption is less as we need to use battery supply, but the Noritakes exceed these MO by leaps and bounds. So I am spending this coming week looking to beef up the battery supply to use the Noritakes.

As to threads on PIC to MO interface, I searched through the MO forum http://www.lcdforums.com/forums/ as well as the PICBASIC and several google searches, but not a thing. I need to work on the next function of the project which is to add graphics.
