Hello vjysnkr58,

Thank you for posting on the forum.
Can you please elaborate on your question? Are you asking for the chromacity of the display?
Which display are you particularly interested in / asking for?

Thank you,

Hello,

I have not heard from original poster (via support).
Do you have a Matrix Orbital EVE display? Can you please share the model and serial number?

Thank you,

Hi Sean, Yes, you got it right. You can keep using the legacy graphics using commands documented in the Protocol manual. Since we have offered the GTT Designer for GUI development, we had made firmware revisions to accommodate newer graphics and their properties. We found that we needed to update th...

Hello Pierre,

Glad to hear that you it worked.
You are welcome.

Hello Sean, The client code, and the examples included work best with GTT Designe r output source files. If you look in the Client\examples\windows, GTTProject17.c and .h are output files from the GTT Designer projects. All the graphic and button (touch regions) created will produce the correspondin...

Hello Sean, Thank you for posting on the forum. When the GTT has events to report, such as keypresses, it puts the data in the appropriate communication buffer. Since I2C is master driven as you mentioned, you will need to poll for data (simply sending a single byte reads). You will also need to do ...

Hello fuzzy,

Thank you for posting on the forum.
I will reach out via support queue and we will update the resolution here.

Thank you,

Hello Pierre,

Thank you for posting on the forum.

If you please try this:
From command line, run MatrixOrbitalFWU.exe with "RecoveryMode" as an argument.

Let me know how it turns out.

Thank you,

Good to hear you got it working, Michael.
Thank you for sharing your code here.

Thanks,

Hello Sean,

Please check Return Message for command 254 55 in the manual.
37645 is the correct module number for the GTT70A-TPC
37636 is for the TPR model; sorry the manual only lists the TPR models

Thank you,

Hi Michael, Did you try to turn flow control off on the GTT? Please check that the autoexec file includes the command to turn the flow control off. Or, if you have left the GTT default (flow control on), and turned the flow control on on your Linux host, did you connect the CTS/RTS lines to the GTT?...

Glad to hear that you resolved the issue.
Thank you,

Hi Sean,

Please try simpler commands for now: 254 0 or 254 55 as you mentioned earlier.
I think you are not giving the write and read scratch pad commands the right parameters.

I wonder if you are taking advantage of the driver code we provide:
Firmware\Client\gttclient

Thank you,

Hello Michael, Thank you for posting on the forum. I see that you have flow control off on your port settings. Please note that the GTT has default flow control on. You can choose to have it off via the GTT Designer project. Can you also please try a simple query command like gtt_get_protocol_versio...

Hello Sean, Good to hear that you get ACKs from the display now. In order to get the GTT70A to reply via I2C, you will need to set the communication channel to I2C. You may please check command 254 5 from the manual . With I2C, all communication transactions are master initiated. To read back replie...
