I have just been able to install MOGD#.

I tried uploading a font via the MOGD# interface, but the upload failed.

I wiped the module file system with MODG# and then tried to upload the font. This time it was a success.

My issue has been resolved.

The SmallFilled font file that I'm trying to upload has 904 bytes, so I send 0x88 (the LSB) followed by 0x03 (the MSB) for the size. The font starts with ASCII character 28 and ends with ASCII character 127, so I send 0x1c and 0x7f respectively. I have tried uploading the file in a couple of ways. F...

I just tried uploading the sample font created in the documentation. {0x05, 0x07, 0x68, 0x6A, 0x00, 0x0D, 0x05, 0x00, 0x12, 0x03, 0x00, 0x15, 0x04, 0x84, 0x2D, 0x98, 0xC6, 0x20, 0x43, 0x24, 0x84, 0x2D, 0x98, 0x19, 0x60} Since this font is only 25 bytes long, I was able to successfully load the entir...

Ah, thank you! This has definitely resulted in some progress. I am now able to send the first 64 bytes of font file. When I send the 65th byte, the display replies with 0xFE, which I think is what it sends back when its receive buffer is full/almost full. However, I have flow control disabled. I hav...

I have tried waiting for the display to echo back data, but this is what I get: Me: Command Prefix (0xFE) Me: Upload Font File (0x24) Me: refID Me: Length LSB Me: Length MSB Display: Confirmation byte (0x01) Me: Confirmation byte (0x01) Me: First byte of font Display: Confirmation byte (0x01) {note ...

Also, when I upload a font file, the display does not echo back each data byte that I send it.

I send the Command Prefix, Upload Font File, refID, LSB, MSB.

The display then sends a confirmation byte.

I send a confirmation byte.

Then I send data, but the display does not send anything back.

I have a GLK19264-7T-1U, and I can no longer get text to display. I was able to use all features successfully (graphing, drawing, text, LEDs, change fonts, on/off/clear, etc.). Then I started playing around with baud rates and flow control settings, since my application was sending data too quickly....

I am uncertain as to the exact bytes that I need to be sending in order to using the draw bitmap directly command for the glk19264-7t-1u. I know that I send the command and the x,y,w,h values. I am confused as to what I need to send for the actual bitmap (the data). The manual says to reference the ...
