4 Buttons / 4 Led's The 4 buttons / 4 led's are supported on the GPIO pins. The mapping is as following:
The GPIO pins are active low (connecting the other side of the button to ground). The status led's are mapped as following:
For the function of the other pins, see here. 8 Buttons / 8 Led's This is implemented using a MCP23017. INTA must be connected to GPIO7, pin 12. See also here. The mapping is as following:
The GPIO pins are active low (connecting the other side of the button to ground). The status led's are mapped as following:
