Re: GTT Protocol Manual Rev 2.1 questions and issues
I've found another issue while writing my code for GTT. I'm trying to load bitmaps (BMP and PNG files) from the SD card, but it's quite erratic. Loading BMP files are almost always OK, only a very few cases I get an eErrorCode_FileNotFound error. Not 100% reliable still, and I'm wondering what could...

Re: GTT Firmware Rev 2.0 capabilities, protocol manual issue
I'll check the 9-slice bar graphs, thank you for the tip. One more issue I've run into: is it safe or advisable to issue the Reset Module command the first time you initialize the GTT LCD in a software? Does it have any impact on the lifespan of the device? And if it's safe to use, then how to know ...

Re: GTT Firmware Rev 2.0 capabilities, protocol manual issue
Thank you for your reply, I'm glad 1, 6 and 8 are considered as a future addition to the GTT Protocol. I'm wondering, if the protocol gets updated and so enhanced with new capabilities, will I be able to update the firmware of my existing GTT50A device to gain access to the new "juice" fre...

Re: GTT Protocol Manual Rev 2.1 questions and issues
The Set Font command did the trick, thank you! I assumed it's not necessary to hassle with that since when you create a label, you specify the font index to use :) And I'm trying to minimize the number of commands sent to the device, since once the user of our software drops 10 or 20 elements on the...

GTT Firmware Rev 2.0 capabilities, protocol manual issues
Hi, I've gone through many documents about GTT, but still not 100% sure if these things are supported by GTT 2.0, so I thought it's best to ask. I suppose most of them would be "not supported", but maybe there's a trick that can be used to achieve these: 1) Is it possible to programaticall...

Re: GTT Protocol Manual Rev 2.1 questions and issues
... and one more thing: now I've made it to update the labels with a different text after each set font size, to see if the label itself gets updated. It does, so the label keeps changing for both Tahoma and Arial Black font, but the Arial Black one doesn't seem to scale with font size setting at al...

Re: GTT Protocol Manual Rev 2.1 questions and issues
... forgot to add: the "Ariblk" text is displayed using the Arial Black font, and it looks okay, but it seems to use the 24 pt font size all the time, no matter what font size I set.

Re: GTT Protocol Manual Rev 2.1 questions and issues
Thank you for the reply. My labels are updating, but with some weird issues. First I thought they use the same font while they shouldn't, but then I realized Tahoma and Verdana looks quite similar :) Now I'm trying to use Tahoma (tahoma.ttf) and Arial Black (ariblk.ttf), both saved from Win7 64-bit ...

GTT Protocol Manual Rev 2.1 questions and issues
Hi, I'm a happy owner of a GTT50A so far. I'm trying various drawing commands, and managing to make things work just fine so far, with one exception. Creating and updating a label works odd for me, it works sometimes, but not when I use multiple labels and multiple fonts. I suppose I'm sending the w...

Re: Proper way of changing baud rate on USB GLK?
Thank you for taking time trying to resolve this. What I initially did and was working 100% fine was: FT_OpenEx(...) FT_SetBaudRate(handle,19200) FT_SetDataCharacteristics(FT_BITS_8,FT_STOP_BITS_1,FT_PARITY_NONE) What I'm trying to do, but fails to work is: FT_OpenEx(...) FT_SetBaudRate(handle,19200...

Re: Proper way of changing baud rate on USB GLK?
"be sure to change the baud rate to the com port being used to match" Since I'm using FTD2xx API, I assumed I only have to change baud rate with the API (FT_SetBaudRate) and with the Change Baud Rate command (0xFE 0x39). Is there a 3rd change I have to apply to increase the baud rate for t...

Re: DriverCore SDK
Thank you. The software I'm working on will not modify or alter the default settings. I just want to detect the default values to make sure the software restores them before exiting, since as it seems, when you close a session, the driver will not revert the LCD backlight and contrast settings back ...

Re: DriverCore SDK
Thank you for the clarification. It's not a huge problem for us, fortunately :) Till it gets implemented, can you please tell me what's the default contrast value for GX Typhoon devices? I'd guess somewhere around 160 (decimal), but I cannot verify that :(

Re: Full bitmap display on USB GLK
Thank you for your reply. I've done more test runs on and measured the performance of drawing pixels vs. drawling lines vs. drawing filled rectangles (on EGLK19264A-7T-USB), and I could see dramatic performance increase when going for drawing lines instead of pixels. At the default 19200 baud rate I...

Re: Proper way of changing baud rate on USB GLK?
"All Matrix Orbital Displays can have their baud rate changed." Yes, I understand that, but when I try to change the baud rate for my displays, any further communication gets corrupted. I've tried to increase the baud rate from 19200 to 28800, 38400, 57600, 76800, 115200 on both ELK204-7T-...
