Arduino-USB-HID-RetroJoystickAdapter/C64_1351_Mouse

USB mouse -> 1351 (C64) mouse adapter (+paddles)

Requirements

• Arduino Pro Micro 16MHz 5V (or Arduino Uno 16MHz 5V)
• USB Host Shield MAX3421EE (USB Host Shield Library 2.0 from Arduino IDE Library Manager)
• 2pcs 10k resistors
• Level shifter for 6 pins

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; // default pin asignments
//Arduino Pro Micro SS=A0(P18), INT=A1(P19):
typedef MAX3421e<P18, P19> MAX3421E;
//Arduino Uno SS=A0(P14), INT=A1(P15):
//typedef MAX3421e<P14, P15> MAX3421E;

Joystick port -> Arduino

• 9 (POTX) -> 10k resistor -> 9 (OC1A) (brown)
• 9 (POTX) -> Arduino Pro Micro: 4, Arduino Uno: 8 (ICP1) (white)
• 5 (POTY) -> 10k resistor -> 10 (OC1B) (orange)
• 6 (FIRE, left mouse button) -> 5 (yellow)
• 1 (UP, right mouse button) -> 6 (blue)
• 8 GND -> GND (black)
• 7 5V -> 5V (red)

+Paddles:

• 3 (LEFT) (Paddle 1 fire) -> 7 (grey)
• 4 (RIGHT) (Paddle 2 fire) -> 8 (purple)

(unconnected: 2 DOWN (green))

USB Host Shield (3.3V) -> Arduino

• SS -> A0 (Arduino Pro Micro), A0 (Arduino Uno) (check UsbCore.h) (3.3V!)
• INT -> A1 (Arduino Pro Micro), A1 (Arduino Uno) (check UsbCore.h) (3.3V!)
• MOSI -> 16 (Arduino Pro Micro), 11 (Arduino Uno) (3.3V!)
• MISO -> 14 (Arduino Pro Micro), 12 (Arduino Uno) (3.3V!)
• CLK -> 15 (Arduino Pro Micro), 13 (Arduino Uno) (3.3V!)
• RST -> RST (3.3V!) (Pro Micro: beware of GND in place of RST!)
• 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 -module!

Hardware

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