I'm trying to upload the small filled font to font id 1. It completes the upload but the LCD is missing characters in the message "If you can read this..."

I can upload the "Small fonts" just fine as well as the "small filled inverse".

Thanks Troy. I will probably use the draw line or pixel commands. The reason that i asked was that I tried to Read the echo after sending a byte of data. The Read always throws the timeout exception. I expected it to work like this:

Loop:
Write(0x05);

echo = Read();

if(echo == 0x05)
Write ...

I have the GLK24064-25 and I want to plot some data and write it to the screen. I use the 0xFE 0x64 command. Do I have to use the protocol of send a byte, read echo, and then ack?
