Hello H, Thank you for posting on the forum. The default setting for serial communication on the GTT is 115200 baud, hardware flow control on. Do you have all the 4 pins connected (RX/TX/CTS/RTS) connected to your MCU? I see that you have this figured out now, though :) You can have your UART hardwa...

Hello R,

Thank you for posting on the forum.
Can you please send a photo of your setup?
The EVE2-70G connection (back of the display where the EVE board is), the flat cable and the USB2SPI all plugged in and powered?

Thank you,
Raquel

Hello bigmaple,

Thank you for posting on the forum.

While you are in mass storage mode, check the USB Mass Storage device property. Go to Details, Children.
You will see there "Matrix Orbital GTT Disk" and its revision number.

Hope this helps.

Best Regards,
Raquel

Hello Markus,

Thank you for posting on the forum.

I am glad to hear that you are happy with the EVE2-38G display :)
Please check out this application note for optimising screen updates.
Description and sample code can be found here.

Hello Sam,

Yes, correct. Sorry this was not so clear.
When you see the GTT screen upon power up, you should be able to connect with GTT Designer Software.
When you see white screen with USB connector image (when jumper is on), the GTT is in mass storage mode.

Thank you,
Raquel

Hello, Thank you for posting on the forum. As per your serial number: 20M01-2188 you have a serial (RS232) GTT70A-TPC-BLM-B0-H1-CS-VPT. What you are seeing in the Device Manager is correct, when you have the mass storage cable plugged in, and a mass storage jumper is installed. Do you have any jumpe...

Hello, Thank you for posting on the forum. The GTT_Rev2.0_Firmware_R2.13.0.10563 is the latest firmware for the GTT series (including GTT35A PCB Rev 3.0). Is your GTT35A freezing issue reproduce-able? I wonder if you please contact us at support@matrixorbital.ca and detail how to reproduce so we can...

Hello,

There is a sample for CMD_BUTTON on the datasheet.
Please check it out, good luck!

Hi Suresh, Very glad to hear that you are moving to production soon. Kindly please check out section 5.8 Coprocessor Faults in the programming guide: https://brtchip.com/wp-content/uploads/Support/Documentation/Programming_Guides/ICs/EVE/BRT_AN_033_BT81X_Series_Programming_Guide.pdf Best Regards, Ra...

Hello blackquetzal, Thank you for posting on the forum.

Hello,

Thank you for posting on the forum.
Can you please tell me which of our Matrix Orbital display series you are interested in?

Best Regards,
Raquel

Thank you for posting on our forum.

Unfortunately, cursor is something we are yet to implement and try out.
Perhaps try out Brigetek or FTDI's EVE forums and hopefully someone has shared their cursor implementation.

Best Regards,

Thank you for posting on our forum.

Glad to hear the you have qualified the hardware by using our exe file.
Unfortunately, we have not much experience with using the EVE Screen Designer.
I suggest contacting Bridgetek, or go try out their EVE forum.

Best Regards,

Glad to hear Ashish, that you figured out the solution.

"Issue is resolved i not initialise MISO pin for SPI, due to this MCU was treating it as normal GPIO pin.
After proper initialization voltage at MISO pin is 3.3V as expected."

Raquel

Hello Ashish, I wonder if you please send me a block diagram of your connections: DSO vs MSP430? You might need to consult the datasheet of the MSP430 regarding running SPI. As you also contact via direct email (support), let us please continue the troubleshooting there and post here when we have it...
