I am now going to make it possible to use the Raspberry Interface buttons as some kind of keyboard. Later I want to make it possible that instead of just printing letters it will print scripts.
I am first going to try to get it work with button 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 Bananaphone fi
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 = button 6 21:s = button 5 22:s = button 4 23:s = button 3 24:s = button 2 25:s = button 1
Now to try the full 6 buttons!
When the 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.
To do this we will add a sleep of 0.5sec at every button:
#!/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 0.5
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 0.5
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 0.5
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 0.5
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 0.5
fi
done
