In this text harry makes it possible to use the buttons for printing text on the screen

New page

== !BETA! ==

first try to see if it can detect the raspberry pi button to make sure if it works I choose to detect the middle number 3.
so we read button 23:s
without pressing the button it says;
0101
and with pressing the right button it says
0000

$ bw_tool -I -D /dev/i2c-1 -a 94 -R 23:s
0101
$ bw_tool -I -D /dev/i2c-1 -a 94 -R 23:s
0000

When we make a shell we have to put the code:
if [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 23:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t Friet is lekker`
fi

in ir
it will look if the place is 0000
and then if that is true it will print the text
after that it is finished

what I found out is that the numbers are mirrored so:
20:s = 6
25:s = 1

Now to try the full 6 buttons!

When in mirror in mind we make this code:

#!/bin/bash

if [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 25:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t W`
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 24:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t i`
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 23:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t z`
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 22:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t a`
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 21:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t r`
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 20:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t d`
fi

with this code you sadly always have to activate it with
./type

now we have to make it possible you can just keep typing and don't have to turn it on again after every time you entered
./type.

#!/bin/bash

while true; do
if [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 25:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t W`
sleep 0.4
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 24:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t i`
sleep 0.4
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 23:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t z`
sleep 0.4
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 22:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t a`
sleep 0.4
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 21:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t r`
sleep 0.4
elif [ `bw_tool -I -D /dev/i2c-1 -a 94 -R 20:s` = "0000" ]; then
echo `bw_tool -I -D /dev/i2c-1 -a 94 -t d`
sleep 0.4
fi

done

for now I added sleep 0.4 sec after every echo
but this doesn't help because now people have to type slower or faster if you change the time. !BETA!
