Hi, I've used the NHD-0216KZW-AG5 in 8-bit mode using the Western European 2 font table. It has performed as expected in 8-bit mode.
In a new design, I am using the 4-bit mode.
As long as I never change the font table, it works properly (albeit with the wrong character displayed). Whenever I try to change the font table, the display begins showing characters that are not in any font table, and eventually stops updating all together. I have to set the font table back to English/Japanese and then remove and re-apply power to the LCD to get the display operating again.
Any ideas as to where I'm going wrong?
