This section talks about using LCDproc with the serial / USB LCDs CW12232 and CW1602 by CwLinux. The CwLinux CW12232 LCDs are graphical LCDs with 122 x 32 dots that also have a text mode with 20 x 4 characters, the CW1602 LCDs are character LCDs that are 16 characters wide and 2 lines high. The modules can be ordered bare or as part of a kit mounted on brackets that fit in half-height 5.25" drive bays. The mounting brackets optionally feature a 6 button keypad that makes use of the keypad connector on the display modules. The kits allow to programmatically switch on/off their backlight. Newer revisions of the kits also have programmable brighness as well as 4 general purpose IO ports. The CW12232 and CW1608 come in 2 variants that differ how they communicate with the host: The serial modules are connected to the PC using a serial RS232 connection getting operating power using the standard floppy drive power connector, while the USB modules only require an USB connection.
