The following table shows the mapping between Arduino pin numbers (D0-D29) and the physical GPIO pins on the CH583 microcontroller:
| Arduino Pin | GPIO Pin Físico | Puerto | Funciones alternativas |
|---|---|---|---|
| D0 (0) | PA0 | GPIOA | - |
| D1 (1) | PA1 | GPIOA | LED_BUILTIN |
| D2 (2) | PA2 | GPIOA | - |
| D3 (3) | PA3 | GPIOA | - |
| D4 (4) | PA4 | GPIOA | I2C0 SDA, A0 |
| D5 (5) | PA5 | GPIOA | I2C0 SCL, A1 |
| D6 (6) | PA6 | GPIOA | - |
| D7 (7) | PA7 | GPIOA | - |
| D8 (8) | PA8 | GPIOA | Serial1 RX |
| D9 (9) | PA9 | GPIOA | Serial1 TX |
| D10 (10) | PA10 | GPIOA | - |
| D11 (11) | PA11 | GPIOA | - |
| D12 (12) | PA12 | GPIOA | SPI1 MISO, A2 |

| D26 (26) | PB10 | GPIOB | I2C1 SDA, A0 |
| D27 (27) | PB11 | GPIOB | I2C1 SCL, A1 |
| D28 (28) | PB12 | GPIOB | A2 |
| D29 (29) | PB13 | GPIOB | A3 |
Mapping rules:
- Pins D0-D15 map to GPIOA (PA0-PA15)
- Pins D16-D29 map to GPIOB (PB0-PB13)
Notes:
LED_BUILTINis mapped to D1 (PA1)- Serial1 uses D8 (RX) and D9 (TX)
- SPI0 uses D16 (MISO), D17 (SS), D18 (SCK), and D19 (MOSI)
- SPI1 uses D12 (MISO), D13 (SS), D14 (SCK), and D15 (MOSI)
- I2C0 uses D4 (SDA) and D5 (SCL)
- I2C1 uses D26 (SDA) and D27 (SCL)
