Read game controllers and joysticks connected to a PIC32MX550F256L. SPI3 clock at 1MHz, connects to an OLED display module, 128x32 pixel, based on the SSD1306 chip.
OLED display connections:
| Signal | Chip | Name | Pin | Chip | Name | Pin |
|---|---|---|---|---|---|---|
| SCK3 | PIC32 | RF13/SCK3 | 39 | SSD1306 | SCK | 3 |
| MOSI3 | PIC32 | RG8/SDO3 | 12 | SSD1306 | SDA | 4 |
| SS3 | PIC32 | RA0 | 17 | SSD1306 | CS | 7 |
| DC | PIC32 | RG9 | 14 | SSD1306 | DC | 6 |
| RES | PIC32 | RE8 | 18 | SSD1306 | RES | 5 |
Digital pin connected to GameCube controller:
- GC RA4 pin 60 via diode, to pull signal line down
- GC RA5 pin 61, direct, to sense state of signal line
Debugging LEDs on dev board:
- LED1 RE6 pin 4
- LED2 RE7 pin 5
- LED3 RE1 pin 94
- LED4 RA7 pin 91
- LED5 RA6 pin 92
PIC32 pin numbers are for the 100-pin package.
LEDs light when the pin is pulled LOW.
MPLAB X V3.45 and 'xc32' V2.15. These are quite old versions now, so I really ought to upgrade!
Microchip ICD3. Other programmers should work, e.g. ICD4 or PICkit4.
