## USB mouse -> 1351 (C64) mouse adapter
|
|
|
|
#### Requirements
|
|
|
|
- Arduino Pro Micro 16MHz 5V
|
|
- USB Host Shield (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;
|
|
//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
|
|
- 8 GND -> GND
|
|
|
|
#### 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!) (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.

|
|
|
|
#### USB Host Shield
|
|
|
|
|
|
#### Level converter with regulator
