Arduino-USB-HID-RetroJoystickAdapter/C64_1351_Mouse

USB -> 1351 (C64) mouse adapter

Pin 9 and 10 needed for TIMER1 - Move SS and INT of USB host shield library 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(P18), INT=A1(P19):
typedef MAX3421e<P18, P19> MAX3421E;

Joystick port -> Arduino

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

USB Host Shield (3.3V) -> Arduino

• SS -> A0 (Arduino Pro Micro) (check UsbCore.h) (3.3V!)
• INT -> A1 (Arduino Pro Micro) (check UsbCore.h) (3.3V!)
• MOSI -> 11 (Arduino Uno), 16 (Arduino Pro Micro) (3.3V!)
• MISO -> 12 (Arduino Uno), 14 (Arduino Pro Micro) (3.3V!)
• CLK -> 13 (Arduino Uno), 15 (Arduino Pro Micro) (3.3V!)
• RST -> RST (3.3V!)
• GND -> GND
• VCC -> 3.3V
• VBUS -> 5V (cut trace from VBUS-pad to resistor!) !: MOSI, MISO and CLK pins are wrongly marked in USB Host Shield DuinoFun UHS mini v2!

Hardware

I used Arduino Pro Micro and module which have AMS1117 3.3V regulator and 8 bidirectional voltage converters.
