Hi there....
I have been playing with my HD44780 40x4 device (pulled out of an old danish train), and i have some questions.....
I see in LCD applications like MP plugin and eg. LCD Smartie, that it is somehow possible to regulate the contrast and the backlight from the software, but what hardware do i need (perhaps to build) to do this ??
Also i have tried the MP Plugin, and while it do support 40 car. i dont think it support 4 lines of text..... ??
LCD Smartie do use all 4 lines, but MP Plugin only use the top 2 lines of the display, leaving the two bottom once blank....
Is this right or what have i done wrong ??
I try the 44780 40x4 driver, is there any one else i should try for this ??
