NEC commands for dislays
« on: May 05, 2026, 07:33:13 am »
Hello,

I currently work on a old VFD display, that can probably receive the NEC commands starting with the ESCAPE character.

I have been told that the format of these ESCAPE commands is:

ESC(0x1B) + "H"(0x48) + 0xdd (this last byte contains the address in DDRAM)

This instruction is probably the equivalent of lcd.setCursor(col, row) , where it will be necessary to calculate col & row from the value stored in 0xdd.

So I need the complete NEX table of commands using ESC: do you where I can find it ?

P.S.: I have read this topic :
https://www.eevblog.com/forum/blog/eevblog-717-how-to-hack-vacuum-fluorescent-displays/
but it does say anything about the NEC Escape commands.
