Emulate a gamepad with ESP32 compatible to PC/Android/Switch

This project merges two source codes to form a single firmware to be compatible with both Nintendo Switch and PC/Android. To switch between Nintendo Switch mode and PC/Android mode can be done by two options:

• Pin 15 (Button to GND)
• Holding the (+) / START button for 10 seconds

Default GPIOs

| GPIO | Button | | ----------------- | ----- | | 3 | Stick Button Right / R3 | | 4 | Capture | | 5 | X | | 12 | ( - ) / SELECT | | 13 | ( + ) / START | | 14 | Dpad Right | | 15 | Sync | | 16 | Home | | 17 | Y | | 18 | A | | 19 | B | | 21 | Stick Button Left / L3 | | 22 | R / R1 | | 23 | L / L1 | | 25 | Dpad Up | | 26 | Dpad Down | | 27 | Dpad Left | | 32 | ZL / L2 | | 33 | ZR / R2 | | 34 | Right Stick X Axis | | 35 | Right Stick Y Axis | | 36 | Left Stick X Axis | | 39 | Left Stick Y Axis |

Soft-buttons:

To complement the miss of some buttons in the switch controller, virtual buttons are defined

| Emulated button | Obtained by pressing | | ----------------- | ----------------- | | L | (+) + B | | R | (+) + A | | ZL | (+) + L | | ZR | (+) + R | | Capture | (+) + Dpad Left | | Home | (+) + Dpad Right |
