the LCD module

So here you can find the current testing version of my module. It can be used to display some text but it has still some bugs ;-)

Usage: To install the precompiled module download the ipk above and install it:

ipkg install kmod-lcd4wl_2430-brcm-1_mipsel.ipk

Then insert the module:

insmod lcd4wl

Using dmesg should show you what to do next.

mknod /dev/lcd c xxx 0 ... where xxx is the major number of your device

After creating the device entry you can access your LCD with:

echo "Hello OpenWRTnrShow me if it's working" > /dev/lcd

for writing to the LCD or

cat /dev/lcd

to read from the LCD.

Here the supported command:

n: Puts the cursor to the next line, on the same position

r: Sets Cursor to the start of the current line

i: Clear Display

h: Move Cursor home

dx: Set Display Status (x=0: off, x=1 on)

cx: set Cursor (x=0 off, x=1 on)

bx: set Blink (x=0 off, x=1 on)

xx: Display shift (x=0 off, x=1 on)

yx: Shift Direction (x=0 right, x=1 left)

ax: Cursor increment (x=0 off, x=1 on)

sx: Cursor shift (x=0 off, x=1 on)
