Hi David, Yes, mostly when strings are involved, null is the end marker hence no need for a length parameter. But there are commands that still need length parameter, eg. command 254 36 - Print Unicode String (as 0 can show up at any point in the string). Good to hear things are working. It sounds l...

Hi David, Thank you for posting in the forum. It is good to hear that things are working well for you and the GTT50A. I am sorry but I see that there is an error in the GTT50A manual. The command 254 37 Print UTF-8 string does not take Length (short) parameter. You may simply send the UTF-8 sting af...

Hi Chris, :) you are welcome for the 'TIA' I will leave Troy with you on the problem (perhaps) regarding drivers. As per your request regarding string extents where you will provide your string and the font id and the display will respond with the width and the height - I can look into that. As per ...

Hi TIA, Thank you for posting in the forum. I am not sure why your display will not upload anymore to the same slot. Have you tried uploading font to a different slot? I deliberately interrupted a font upload to see if I can replicate, but (un)fortunately I was able to upload to the same slot again....

Hello Paul,

Thank you for posting in the forum.

We can send you the firmware file for the (E)GLK19264A .
If you please send me a PM with your email address we can take it from there.

Thank you and Best Regards,

Hello skassan,

Thank you for posting on the forum.
Yes, there is such an option; we will have to set you up with a custom display order.
If you please send me a PM of your email address we can discuss details regarding your requirements.

Thank you and Best Regards,

Hello, Thank you for posting on the forum. You are right, the B19264A-BK drawing may be used for the LK204-7T-1U displays as we made sure that the layout and dimensions of these two displays are the same. My colleague who works on these drawings is away and will be back on Monday - I will make sure ...

Edited Post: Please make sure that you have not inadvertently locked the display. If you please check out Data Security (hardware or firmware data lock) in the manual . Hi Tamas, I have tried 57600 baud on my GLK19264A here (should be the same as the EGLK) and it works fine for me. Please be reminde...

Thanks Dave. The serial numbers I was looking for are the '14M07-5601' and '14M07-5602'. You should have the latest firmware on your GTT's. I have tried both GTT70A and GTT50A with the same firmware as yours and I did not have troubles calibrating them. If you please re-try calibration, making sure ...

Thank you for posting on the forum. It sounds that you are doing calibration correctly, I apologize for the troubles you are having. Have you ever had successful touch calibration with these displays before? Are you using GTT Support Tool in sending the calibrate command? Also, if I may please get t...

Hi,
You are right, the bars should not be equal; 40 should be a pixel higher than 39 such that value 40 should have ended on Y=0.
There is a bug on the code, if you please pm your email address and I can try and send you a firmware update.
Thank you,
Raquel

Hello, Thank you for posting on the forum. You are correct, we have changed the implementation of the old strip chart that was only able to scroll in 8 pixels. I apologize that the documentation may have not been too clear and therefore causing you troubles in setting up / drawing strip charts. The ...

Sent you the profile / template via PM.
Please let me know how it turns out.

Hi,

An FTDI utility called FT_Prog may be used to program the VID and PID.
I will get you the profile once I have it tested here.
The LK204-7T-1U-USB should have VID and PID values of 1B3D and 012C as you mentioned.

Sorry for the confusion.

Hello, Thank you for posting on the forum. The problem as you described does sound like a buffer overflow issue. Unfortunately, the LK204-7T-1U / -USB modules do not offer hardware nor software flow control features. I apologize for the mention of 'pins five and six..' on the manual, as this does no...
