| simno | 0:fa0736e4d371 | 2 | // The SKPang board has a joystick wired to pins 21 to 25. |
| simno | 0:fa0736e4d371 | 3 | // This is my first go at using BusIn to read multiple pins as a bus. |
| simno | 0:fa0736e4d371 | 4 | // My biggest surprise is that the pins are high all the time unless the joysick goes left, right, up, down, click |
| simno | 0:fa0736e4d371 | 5 | // at which time each goes low. |
| simno | 0:fa0736e4d371 | 6 | // The text output goes to the serial out, if it is running, and the Mbed internal leds represent: |
| simno | 0:fa0736e4d371 | 7 | // 1 = left |
| simno | 0:fa0736e4d371 | 8 | // 2 = up |
| simno | 0:fa0736e4d371 | 9 | // 3 = down |
