Re: any tips on unsoldering the tiny jumpers

Hi Ghost, With your brand new LK202-25-V units, you'll have 3 x 0603, 0 ohm resistors to remove from the RS232 protocol block, and 2 x 0 ohm resistors or solder connections to make on the I2C block. Two soldering irons would definitely help here, but one will do the trick. The resistors will typical...

Re: any tips on unsoldering the tiny jumpers

Hi Ghost, I understand you'd like to move your protocol select jumpers from RS232 to I2C communication. Are you still working with your LK162-12, or is this another display? First, I would recommend using caution, any damage caused during modification may not be covered under warranty. That said, I ...

Re: LK162-12 acting up can i reset it? ~TX/RX labeled backwards!

Hi Ghost, The manual for the LK162-12 Rev 2.2 display is legacy, no further updates are planned for that document. Given that Rev 2.2 was replaced by Rev 3.0 over 7 years ago, I suspect that manual is no longer downloaded. However, I understand the importance of this issue. Therefore, I have drafted...

Re: Load Bitmap return message missing a byte

Hi David, I appreciate you bringing that issue to our attention. I did a quick test this morning, loading the start screen (Logo70A.bmp) into slot 1, and I did receive the correct 252 95 0 1 254 response back from the unit using the Support Tool. If you could provide your firmware version and any ad...

Re: LK204-25 strange characters

Hello Mario,

When communicating to the display, please ensure you are using 8 bits data, no parity, and 1 stop bit. You might also try using a shorter cable and ensuring your host and the display have a common ground connection.

Re: LK204-25 serial protocol

Hello Mario,

The LK205-25 has a 128 byte input buffer, which is difficult to fill even at 115200 baud. Should the buffer fill the display will drop characters, at which point you might consider reducing the baud rate or adding delays.

Re: GTT 5 and 7 Rounded rect missing corners

Hi grnbriar,

Yes, all GTT firmware is field upgradeable. You'll simply replace the upgrade.bak file on your SD card with the most recent version from http://www.matrixorbital.ca/software/GTT2.0/GTTFirmware, and cycle power.

Thanks,
Troy

Re: Toggle GPO ports

Hey Ben, We were just talking about adding a new feature to the GTT that I think could help here, so it would be great to get some developer feedback. What about a toggle button? With scripting, I believe that feature would provide the GPO toggle ability you need. Let me know what you think. Cheers,...

Hi Paul, I apologise for the inconvenience of this issue. Could you please download the filesystem from the unit you have configured and send the .ebin file to me at tclark@matrixorbital.ca? If you can confirm that the only setting change missing from your configuration is turning the keypad backlig...

Re: Any other displays compatible with GTT 7 and 5?

Hello grnbriar, You are correct, the GTT50A and GTT70A share the same 800 x 480 resolution. Unfortunately, a 4" GTT has never been offered. To make code reusable across the GTT line you might position elements relative to the width and height of the screen. All GTTs will return their width and heigh...

Re: EGLK19264A-7T Setting start up brightness keypad

Hi Paul,

No worries, I'm glad the work around was successful.

A release date for the next firmware version has not been set at this time, but I expect you'll see an update in the firmware upgrader within the first quarter of the year.

Cheers,
Troy
