I executed the instructions provided and the utility returned success.
This code now results in the output indicated below the snippet
............................................
MSComm1.Output = Chr(254) & Chr(72)
MSComm1.Output = "AAAAAAA"
MSComm1.Output = Chr$(254) & Chr$(71) & Chr$(1) & Chr$(2)
MSComm1.Output = "bbb"
MSComm1.Output = Chr$(254) & Chr$(74)
MSComm1.Output = "cc"
...............................
Line 1:ccAAAAA
Line 2:bbb
No underline
254 + 83 = no block either.
Next?

From uProject.exe:
Read Module Type = ""
Read Serial Number = FF FF
Read Version Number = FF

Serial number should be FFFF unless you've programmed it. uProject doesn't detect the display type properly with these ones. The one I'm worried about is the revison of 0xFF, which indicates that your memory is not initalized. Does your display have a startup screen still?

No., no startup screen.
I havn't programmed the serial number.
I havn't received anything from support regarding my request to return these either. I don't have time to 'fix' the product. I need to get a product that works.

I have exactly the same problems as described by dconnell. I can't get block or underline cursors to work.
Don't think I can tell what my PCB revision is, as I have an MX2, and I guess I can't see the etching. There's a handwritten serial of '03M08-827'. My firmware revision comes back as 0x20. I don't want to try the firmware upgrade as I'm not sure what the PCB revision is.
I have a second MX2, but haven't tried that one yet.
Can I have some support, please ?

Sounds like you have the memory file that has the bug. Head over to
http://www.lcdforums.com/forums/viewtop ... highlight= and follow the instructions at the bottom of the page. Let us know how it turns out.
URLs are not working

James, those two URLs are consistently returning an HTTP 404, but our internet comms are fine at the moment. Can you expedite please ? There is a commercial project depending on this. And is there any chance of using e-mail rather than the forum ? Many thanks.

I'll get those files back in place ASAP. Looks like somebody moved them on me.

Hope this helps.

James, that new memory file has fixed the problem. Thanks.
You may already know, but just wanted to point out that, when altering Contrast and Brightness with uProject, spurious characters are sent to the display (from the top half of the ASCII table).

When changing contrast with uproject, random characters do appear...no worries it's a bug in the software not the display!! Were working on it!8)

Good to hear those instructions worked (again). And to think all these problems are caused by one misplaced byte
I'm just glad the fix is so easy.
