I was thinking about getting the display but had several question about the software that are used for the screen.

1. The software used is a MOGD#. When I install the software provide on the site, I couldn't find the display type listed. I was wondering is there a newer version of the software or will the a cd software be provided if I were to get the screen?

2. I notice that the sample code for the screen are written in C#, which I'm not to familiar with. I was wondering instead of writing C# code, I can write the code in C langauge.

3. I was reading the demo on the touch screen and notice that there a evaluation software that I could run provide from site but I couldn't locate the software anyway. Is the software on the site or will it come with the display if I do decide to get it.

Thanks,

Hi tweety04,

Thank you for posting on the forum. Thank you also for your interest on the GLT240128.

1. MOGD#: there is a newer version that includes the GLT240128. I will get that up on our site shortly.
2. Yes, you should be able to use C instead of C#. The sample is there for your reference.
3. The evaluation software can be found in the bin folder of the GLTAppNote.zip. Please check out thispage for instructions.

If you have more questions, please post them here.

Best Regards,

Thanks for the quick response and updating the site with the newer version of MOGD#. I had a feeling that I could use C and just wanted to be positive about it. The evaluation software seem to be only helpful if I already had the display, but thanks for posting up the link.

Hi,

Without having the display yet, you can start by looking at the sample source code in the GLTAppNote zip. They are *.cs files.

thanks you for pointing that out. I'll will look into that.
I have another question regarding the GLT and the GLK display. I was wondering what is the difference between the two display, both hardware and software? Is the only difference is that one is touch screen and the other isn't??

Hi,

Yes, functionality and features are pretty similar, except for the keypad on the GLK and touch screen panel on the GLT. The firmware reflects this difference as well, where all the keypad commands would be missing on the GLT; and touch screen commands missing on the GLK.

There is also a bit of a difference physically on the display modules, but the DB9 and power/comm connections are on the same spot; and the mounting holes are the same.

I hope this helps.

Yes that helps.
I notice that the on board memory has 16KB for fonts and graphics but what if I wanted to use more graphics than what the memory can handle. Can I use extern memory to store the graphics? I plan on connecting the display to a PIC to handle the code.

You can use the directly draw bitmap command (command 254 100, see manual for details) to send any data to be displayed thats not stored on the unit its self.
