Hello, I try to understand bit by bit, how the Rainbowduino shield works.
I don’t want to control the board over I2C, I will learn to program it directly.
On the sketches I understood, I have to fill shift latches over two output pins, and I have to switch otuputs for the LED driver. But I don’t understand how I have to control the power of the leds. Have I make a PWM on the outputs? What is the right way? The default programs are very difficult to understand for me. I am not able to read the function in it.
by the way are there more technical ressources for the Rainbowduino? I found only the PCB and the SCH and a very short pdf which shows the function of the demo progs.
