I have a GLK12232-25SM Rev 1.1a. The module returns 21 as the module version. Does a relation between revision and firmware version exist? If so, what is it?
The only thing I could think of is (left to right) bit 1 to 4 high version number, bit 5-6 low version number, bit 7-8 suffix. (21 dec = 00010101 bin)
thanx in advance...

Hi Tom,
To be honest, I don't really care which pcb version works with which firmware version. As long as it works I'm happy
But what I would like to know is how to tell the difference between the displays. (and of course the supported functions) The manual of the GLK12232 rev 1.1 and 1.4 is different, but how do I know which display I have when the version returns 21 as a value.
In short, what does the "21" mean?
Regards,
Jeroen

Jeroen,
The version number saying "21" is the firmware revision. The actual firmware revision is 2.1, which may have a sticker on the processor with "2.1" printed on it. What the manual goes by is the pcb revision. The "get version number" command won't be too helpful to you for telling the difference. Our support website will indicate what manual you can download according to pcb revision. You can refer to the GLK12232-25-SM manuals at http://www.matrixorbital.ca/Manuals/GLK ... 232-25-SM/ .

Hi Tom,
Thanx for your answer, but unfortunately it's not of much help.
For me it's "important" to know what features are supported by the connected display. (and not just the display I have) Based on the version number there's no way for me to know what the connected display is capable of.
For instance my display (rev 1.1a, firmware 2.1) does not support backlight brightness. So if I send that command to the display, all I get is a lot of garbage on the screen.....
