hi henri,
i get a new vfd NEC FC20X2JA-AB ,it Compatible with Noritake CU20026SCPB-T30A ,first i will test in serial interface not work
and i change try in pararell ,it work!! , i use circuit t23a from here ,overall timing not change ,and it can display character on screen , but not completely ,you can see that my picture
maybe control command such as "clear screen" or another commnad , can't work
i see in datasheet in T30a ,it's different form t23 in pin A0 ,if use write a command ,you will active A0
Can you add t30a in your noritake t-series or you can share this driver for i contribute to t30a
thank you
