I paired up my gumstix with a PS3 controller via bluetooth. Gumstix needs to
be able to decode the signals sent from the PS3 controller and use them to
perform some functions. Which pin should I get my data from and how? I guess
probably need to write an interrupt in this case?
Should I be using the BTUART? In this case, they were set as the following:
echo "AF1 in" > /proc/gpio/GPIO42
echo "AF2 out" > /proc/gpio/GPIO43
echo "AF1 in" > /proc/gpio/GPIO44
echo "AF2 out" > /proc/gpio/GPIO45
Isn't this a little redudant? which pins should I be monitoring and how?
