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)
