I see that command 0xFE 0x45 is only being sent when Keypressed is 0x48, maybe you want to change that to send 0xFE 0x45 outside that if (Keypressed== 0x48) and send it when Keypressed is not 0x00?

my goal is to read entered key once and run some commands and clear the buffer for the next run of the loop If you do this, KeyPressed will remain to be whatever it was last read. So you need to be sending the 0xFE 0x26 Poll keypress command again and KeyPressed should then be 0x00 value. Ie. make ...

Hello, Thank you for posting on the forum. Your command is correct; I will check this out with a current LK204-7T-1U-USB (firmware v5.0) display and let you know. Update: I tested the command on a current display and it works fine. Can you please tell me what you observe the display is doing; and pe...

Hi, I thought you already hooked up the display to the USB headers on your motherboard (first post)? You will need to read up on the pin out of the connector as per your motherboard's manual. What kind of internal USB cable do you have? We do sell our own like this one , but other people also sell i...

Hi, Using the external USB connection, when you plug in the GX, Windows (if that is what you have) should start looking for the drivers for the display. You can find the drivers here . Installation information here . If Windows does not ask for drivers, check if the device shows up in the Device Man...

Hello, If you please check out the instructions on page 6, which is the Serial section of the manual. It has pictures to hopefully make it easier to follow. The Serial section of the manual mentions the use of uProject and Hyperterminal. Try Hyperterminal to start as it is readily available on Windo...

Hi,

With your existing code, can you please try to change the defined i2C_address from 0x28 to 0x50?

Just give it a quick try.

Thanks,

I clipped this from Wikipedia: A null modem cable is an RS-232 serial cable where the transmit and receive lines are crosslinked. In many situations a straight through serial cable is used, together with a null modem adapter. The adapter contains the necessary crosslinks between the signals. So, to ...

Hi, Thank you for posting on the forum. Read Customer Data command is 254 / 53. Immediately after receiving this command, the display should start transmitting 16 bytes. If these 16 byte - customer data are not set, they will read as 0xFF's. Have you successfully read from the display at all? You ca...

Hi, Would I be able to connect the power through the 4 pin headers Yes, this is how you power the display. Please see page 6 of the manual regarding the 4 pin connector (marked #5). And for serial transfers, I'm not using the 4 pin header but using the RS232 port on the back of the LCD to a serial p...

Hi, The display speed is default at 19200, I see that you have your code set at 9600. As for the 4 pin connector: Vcc - connect this to 5V RX - connect this to the TX of the ATmega128 via a RS232 transceiver TX - connect this to the RX of the ATmega128 via a RS232 transceiver Gnd - connect this to G...

Hi, Sorry about the documentation, I confirmed that it is incorrect. There should be no need for the first confirmation byte (the one before the font width is sent by the host); as laid out in the table on page 44 of the manual . I have told the technical writer and he said he will look into this ma...

There is a sample code in the ATmega128 on page 178. Try if that will make it better. I see that it needs to check UDRE bit in UCSRA register before writing to the UDR.

Glad to hear that you have figured out what was wrong.
We will take a look at the manual and make sure that it describes the character table more clearly.

Hi Ted, Thank you for posting on the forum. Hopefully there is not really a need for you to upload the font files during run time. If you have your defined fonts, you can upload them using mogd# . If you DO need to have your fonts uploaded during run time, first we need to make sure that the font fi...
