Good find. The 'pigs' program that comes with the pigpio.tcz extension
allows pins to be controlled by PWM. So in fact it's very easy to
control the brightness on this board.
Maximum brightness:
Code:
--------------------
tc@piCorePlayer:~$ pigs PWM 13 255
--------------------
Off:
Code:
--------------------
tc@piCorePlayer:~$ pigs PWM 13 0
--------------------
It should therefore be straightforward to write an applet to call
'pigs'. In fact, there are already a couple of applets to start from -
there's the pCP one that is intended for the official display, and
there's one that was written for the Joggler. Either of those should be
a good basis for a Pirate Audio brightness applet.
