With this program you can send commands to the Seiko/Epson 1335 LCD Controller and see what happens. This tool should help developing programs for the cpad character device.

Installation

To compile the program, you need libmagick and libreadline with header files. Then do make and make install, if you want to install the program to /usr/bin.

Description

Run cpadconsole and type in help. You can get the command line options with cpadconsole --help.

Video Memory

The following memory areas can be used:

    0 -  8191
16384 - 24575
32768 - 40959
49152 - 57343

The size of each area is 8kB, and they are in fact all the same memory. The total memory is thus 8kB, and it can be accessed throught four different address areas.

Example

The following example will bring the sed1335 to combined text/graph mode, display the image test.gif and the text "Hello World!". The image will flash at 16 Hz, so it seems to be gray. Run cpadconsole and type in the following:

sysset char_height=8
display screen2=flash2 cursor=flash2
cursorform shape=underscore
overlay screen1=text
scroll screen1=4800
display on
cursor 0
writeimage test.gif
cursor 4800
writetext "Hello World!"
