Hello,

I want to use LK204-25 for my project and i went thru the manuals, can you give me some clarification regarding how these normal text and the command is differentiated. In manual it says 0xFE prefixed with cmd no will be treated as command for the lcd, but if i want ot display FE itself will it
take as command or just text.
I am using FPGA for interfacing.

can u help?

Hello raghuksn,

Thanks for your post.

I am most certain that the reason why you are seeing the command prefix (0xFE) as FE on the display screen is because you are sending the data as ASCII. Here's an example:

to display an 'A' : you send 0x41
to display an 'F': you send 0x46
to display an 'E': you send 0x45

but to send 0xFE as command prefix is to send 0xFE (1 byte value, instead of most likely two values you are sending, 0x46 and 0x45, hence you see an 'F' and 'E'.

Please let me know if this helps,
