Hello Pierre,

Thank you for posting on the forum.

You may solder a zero resistor on R75 and you will get 5V on the GPO header, bottom right, marked 5V.
You may supply up to 500mA from the 5V rail.

Thank you,

Thanks, we got the email.
We will look into it.

Hello,

Perhaps you can share your code here so we can take a look.

Hello JPanu,

My apologies, I was looking at the wrong header.

Please make sure that you have the D+ and D- connected properly on your cable.

Thank you,

Hello,

Thank you for posting on the forum.
The EVE2-38A and EVE2-35A do not share the same timing information; this is why the same code will not work on both displays.

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 ...

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 ...

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 ...
