#cfa_linux_examples

Linux-compatible(*) command-line example programs with C source code. Supports Crystalfontz Intelligent LCD Modules using USB and serial interface including CFA533, CFA631, CFA632, CFA633, CFA634, CFA635.

CFA735 and CFA835 can be demonstrated using the CFA635 example.

#Basic Installation

These are generic installation instructions: (Note that gcc v3.0 or later, make and their supporting libraries are required for this utility to work.)

#Extracting the bundle

• Extract the files contained within the cfa_linux_examples.tar.gz archive to the desired location.
• To extract the files use the command: "tar -xzvf cfa_linux_examples.tar.gz"

#Compiling from source

• 'cd' into the created folder and use 'make' to compile and create the example binaries.

#Executing the programs

• The example utilities run with the command line options of:

~$ ./example-XXX PORT BAUD
   PORT is something like "/dev/ttyS0" or "/dev/usb/ttyUSB0"
   BAUD is 19200 or 115200
   To clear the display, enter "clear" as an optional third parameter

• The screen output should show something similar to the following:

----------------------
-  >This is line 1<  -
-  >This is line 2<  -
----------------------

#Notes on Baud Rate This utility may be used to test the 631, 632, 633, 634, and 635 displays.

BAUD rates for the modules are as follows: 631 USB: 115200 632 USB: 19200 633 USB/Serial: 19200 (default) or 115200 (FW v1.4 and beyond) 634 USB: 19200 635 USB: 115200

If the above baud rate does not give any output on the LCD, try 19200 or 115200 as earlier/later models of a USB LCD may use a different baud rate to those shown above.

#Make options If you modify the existing code and wish to do a fresh make, run 'make clean' and then 'make' again.

#Source Code Source code for the example utilities are also contained in this archive. See the extracted sub-directories for the C source code.

(*) This source code (with a few minor modifications) should also work under other operating systems. If you would like to have us (Crystalfontz) help you make these work under a different OS, please email us.
