ABOUT¶

A simple class for reading a Super Nintendo (SNES) controller's buttons.

HARDWARE¶

The library was developed using the Nordic mKIT and cheap controllers.

NOTE: This controller has a wide VCC tolerance and continues to operate even when the mKIT is running off of a coin cell battery.

USAGE¶

After wiring up a controller:

#include "SNESController.h"

SNESController snes(P0_20, P0_21, P0_22);

uint16_t state = snes.read();
if (snes.pressed(state, SNESController::SNES_BUTTON_RIGHT_ARROW)) {
    ...
}

Ticker ticker;
ticker.attach(periodicCallback, 0.05);
