Arduino-USB-HID-RetroJoystickAdapter/C64_1351_Mouse

Pin 9 and 10 needed for TIMER1. Move SS and INT of USB host shield away

C:\Users\xxxxx\Documents\Arduino\libraries\USB_Host_Shield_Library_2.0\UsbCore.h:

//typedef MAX3421e<P10, P9> MAX3421E;
//Arduino Pro Micro SS=A0, INT=A1:
typedef MAX3421e<P18, P19> MAX3421E;

Joystick port -> Arduino

• 9 (POTX) -> 1k -> 9 (OC1A)
• 9 (POTX) -> (ICP1) Arduino Pro Micro: 4, Arduino Uno: 8
• 5 (POTY) -> 1k -> 10 (OC1B)
• 6 (FIRE) -> 5
• 1 (UP) -> 6

USB Host Shield -> Arduino

• SS -> A0 (Arduino Pro Micro) (check UsbCore.h)
• INT -> A1 (Arduino Pro Micro) (check UsbCore.h)
• MOSI -> 11 (Arduino Uno), 16 (Arduino Pro Micro)
• MISO -> 12 (Arduino Uno), 14 (Arduino Pro Micro)
• CLK -> 13 (Arduino Uno), 15 (Arduino Pro Micro)
• RST -> RST
• GND -> GND
• VCC -> 3.3V
• VBUS -> 5V (cut trace from VBUS-pad to resistor!)
