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.

By connecting his scope to a pin that was toggled on and off with /sysfs he found – to his horror – the maximum speed of the BBB’s GPIO was around three and a half kilohertz. Something had ...

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 ...
