But the key benefit is that different pins can handle the same purpose. For audio the Greater Than Zero Pis (GTZPi) use PWM0_OUT and PWM1_OUT on the processor’s GPIO pins 40 and 45.

Now instead of wrangling Python or PHP to do your bidding, [Eric] came up with a way to control the GPIO pins on his Raspberry Pi in a browser. [Eric] calls his project WebIOPi, and it’s the ...

There can be several GPIO pins that depend on the application of the chip. Figure 1: GPIO in a System The pins can be programmed as input, where data from some external source is being fed into the ...
