Hello bobb,

Thank you for posting on the forum. Can you please email me at rmalinis@matrixorbital.ca.

Hi AJB2K3,

Thanks for posting on the forum.

The screws for the MX232 are 4-40 1/2".

Hi cloud_171, Thank you for posting on the forum. If I understand you right, the fan does not automatically turn on when you connect it to the MX400? Does it turn on after sending GPO commands? Please see the manual for commands 86, 87, 192, and particularly 195 which is the state of the GPO upon po...

Hi Davey, Thanks for posting on the forum. The GLK24064-25 is composed of the LCD and the Matrix Orbital board which are held together via the soldered 2x10 connector on one of the short ends of the board, and on the other short end are 2 connections for backlighting. Also, note that we squirt some ...

Hi Adan_T,

I have searched for cstdio.h myself and I can't find it. Jon should know where we can get that, I have a feeling though that he created that one himself. But he is not in today, when he shows up tomorrow, I will definitely get him to share you that header file.

Hi Adan_T,

What compiler are you using?

Hello Jeroen,

Pardon me for the statement about the software. I did not know the history until now.

If I can get your email, I'll make a list for you tomorrow.
Mine is rmalinis@matrixorbital.ca

Hi spillner, 1. You are not misuing mogd.exe, I confirm that the drawing canvass is set to 240x64 (which is the current largest size of MO graphic displays). No matter what size the settings are in, the canvass remains at 240x64, and so yes, this is a bug of the software. Because of this bug, the so...

Hi spillner, I wonder if you could please try something out for me. On your communication and power cable, please swap the two middle pins, I believe they are white and green wires. Place the white wire to where the green is, and the green to where the white is. I believe, if you can read on the PCB...

Hi Frozenstiff, Thank you for posting on the forum. Is this problem persistent in every power cycle? Can you send text continually? Does the unit it wrap and scroll the text? Also, is it possible for you to post a picture of the display? I am not sure with "bottom line of the text missing and t...

Hi escsco, Unfortunately, the VK204-24-USB does not support large digits. We are in the process of re-designing the VK204-24-USB and the large number support is definitely in it. In fact, with the re-design we are doing, we are implememting large numbers on any display that has 4 lines. Sorry for th...

Hi Adan_T, Unfortunately, there isn't a way to display your variable straight out. You will need to do some extra work. Since numbers 0 - 9 can be displayed in the display by sending 30d to 39d, you can easily increment each digit this way, but then you need to know which digit is to be incremented ...

Hi Adan_T, unsigned char number[5] = {'1','1','5','0','0'}; void Transmit_String(unsigned char txt[], unsigned char length) { unsigned char i; for (i = 0; i < length; i++) USART_Transmit(txt ); } then call Transmit_String(number, 5); somewhere I am not sure if this is what you are looking for

Hi Adan_T, Your USART_Transmit function accepts only unsigned char data, by doing USART_Transmit(txbuffer_numbers[0]); which passes a long int to the function, you will be losing your large number and only the last 8 bits will actually be sent. Also, when you actually do this: txbuffer_numbers[0] = ...

Hi Gerry, I am sorry to hear that Murphy got to you (who does he not get to, huh?) Would you happen to have a scope? Can you please scope out pin 3 which is the Vee (contrast) for the display. There should be some form of PWM on this pin, but between 0 to 5V. I have a feeling contrast is too low tha...
