Empowering USB CS-LCD with Backlight and Keypad
Yesterday, i look back on my usb cs-lcd again and try to make keypad input working. Add several lines of code to scankeypad in hd44780_functions pointer, making it came true. Now, it can allow up to 8×4 matrix keypad to be used as the input. Running lcdexec as client bring us a menu system on our HD44780 LCD. Backlight can also be controlled from this menu. LCDproc is a great lcd daemon…
