CrystalFontz offers a wide range of character and graphical LCD modules. The CFontzPacket driver supports the modules that communicate with the host computer using a packet-based communications protocol with 16-bit CRC (hence the driver name). Currently this line of modules comprises the models: CFA-631 20x2 character LCD with backlight keypad with 4 keys: Up, Down, enter & Escape USB connection for data and power mounting bracket to fit into 3,5" drive bays Optional (via add-on board) temperature sensor, fan and ATX power control connectors (all unsupported by LCDproc) CFA-633 16x2 character LCD with backlight keypad with 6 keys: 4 directions, Enter & Escape serial or USB connection mounting bracket to fit into 5,25" drive bays Temperature sensor and fan control connectors (both unsupported by LCDproc) CFA-533 This is the same as CFA-633 except it misses the fan control capabilities. The temperature monitoring is not supported in LCDproc though. CFA-635 20x4 characters LCD with backlight keypad with 6 keys: 4 directions, Enter & Escape USB connection for data and power four bi-color LEDs to show status information optional mounting bracket to fit into 5,25" drive bays Model = { 533 | 631 | 633 | 635 } Select the LCD model that is connected. Legal values for this option are 631, 533, 633, or 635, with the default being 633. Device = DEVICE Select the output device to use. It may be a serial device or a USB device in serial emulation mode. If not given, it defaults to /dev/lcd. Mac OS X users may need to use one of the /dev/cu devices instead of the /dev/tty ones. USB = ¶meters.yesnodef; Enable this flag if the device is connected to an USB port. For serial ports leave it disabled. [default: no; legal: yes, no] Size = ¶meters.size; Select the LCD size. This overrides the size the driver uses for the selected model (631: 20x2, 533/633: 16x2, 635: 20x4). You should usually not need to set this value! Contrast = CONTRAST Set the initial contrast. Legal values for CONTRAST are 0 - 1000. If not specified, it defaults to 560. Brightness = BRIGHTNESS Set the initial brightness [default: 1000; legal: 0 - 1000] OffBrightness = BRIGHTNESS Set the initial off-brightness [default: 0; legal: 0 - 1000] This value is used when the display is normally switched off in case LCDd is inactive Speed = { 19200 | 115200 } Override the default baud rate the driver uses for communication with the selected LCD model. Allowed values are 19200 (default for CFA-533 and CFA-633) and 115200 (default for the CFA631 and CFA635). You should usually not need to set this value! OldFirmware = ¶meters.yesnodef; Very old 633 firmware versions do not support partial screen updates using 'Send Data to LCD' command (31). For those devices it may be necessary to enable this flag. [default: no; legal: yes, no] Reboot = ¶meters.yesnodef; Reinitialize the LCD's BIOS [default: no; legal: yes, no].
