Re: EGLK19264A-7T-USB connection problem

Hi Benedict, It sounds like only the first of the two drivers required for the EGLK19264A-7T-USB has installed correctly. Please search your device manager for any devices that show an error icon. If you cannot locate the EGLK device driver that has not been installed, you might try to uninstall the...

Re: EGLK19264A-7T-USB connection problem

Hi Benedict, The EGLK19264A-7T-1U has a USB to Serial converter onboard which appears to your system as a virtual COM port. To determine the port to which your display is connected, you can right click Computer and select properties (or Windows Key + Break). From the System screen that appears, you ...

Re: LK204-25-USB woes on Fedora Linux

Hi Andrew, No worries, I understand that without being able to see the screen it will be difficult to debug with a simple string. You might try using echo to send a command such as Read Module Type (254 55) which should provide a response if successful. Your code snippet looks good. To send characte...

Re: Howto use LCD of a HP TouchSmart IQ820

Hi lcdeee,

Sorry to hear about your IQ820, but the information in this Forum is specific to Matrix Orbital displays.

All the best in your search for a solution,

Re: LK204-25-USB woes on Fedora Linux

Hi Andrew, It looks like lcdproc is having trouble communicating to your display. I would recommend using echo commands within terminal to confirm that you are able to communicate to the display. Once you have confirmed communication, copy the settings over to your configuration files, specifically ...

Re: Keyboard Matrix behaviour

Hi Ronny, Multiple key presses can be detected using the current GTT70A hardware, but implementing the functionality in firmware will require significant changes including a new, unique return value for each multiple key combination. If possible, I would recommend implementing a simpler toggle style...

Re: Label update speed

Hi Ronny, I appreciate your feedback regarding the GTT70A, and believe I have been able to replicate your test conditions. Using a 6pt arial font, it takes approximately 4 seconds to visually update 32 labels displaying the extended date and time. However, using the default font, updates require les...

Re: Beep printing 7 char string

Hello David, Good to hear your code is up and running, we have taken care to use the same code base for all units in our GTT Rev 2.0 line. You can communicate to a GTT70A, GTT50A, or GTT35A in the same way, using the same commands. The GTT50A and GTT70A even have the same pixel count, 800x480, so co...

Re: Mogd# crashed while uploading font

Chris,

Unfortunately, at least for this issue, my unit has been running well all weekend and so far this week, without raising any exceptions. If you find anything more on your end please let me know.

Cheers,

Re: LK204-7T-1U custom character

Hi user8547, The implementation of your createchar function looks good, until the last line. You are only transmitting a single byte, which is the uninitialized ninth value or your degree array. You might try the following: Serial1.write(degree, sizeof(degree)); Also, please note that Serial.write e...

Re: VFD very low bright

Hello Tawyxxz, The manual override procedure will force the brightness setting of your VK204-25 back to the default value. I see you have also confirmed the unit responds to manual brightness commands. Unfortunately, this unit may be suffering from a hardware fault. If you could please provide the s...

Re: Mogd# crashed while uploading font

Chris, This is a funny one indeed. I added a catch for the Unauthorized Access Exception to your send function in SerialIO.cs, in the same manner as the existing IO Exception catch, and put breakpoints on both to try to start tracking down the source of the error this morning. Unfortunately, everyth...

Re: Built around an MXO GLK display!

Chris, I did notice your code, and thought the beep may have been for diagnostic purposes, just wanted to let you know the command is there if you want it. I see volume is on your to-do list, along with a few other interesting features. I'll take a look at your ScrSomething class when I get a chance...

Re: Mogd# crashed while uploading font

Hi Chris,

I'm up and running, thanks again.

I have observed two System.UnauthorizedAccessException: 'Access to the port is denied' exceptions, and have now setup a break point on your System.IO.IOException catch. I'll let you know what I find.

Cheers,
Troy
