I would like to understand what for each device connected to a rPI input or output what GPIO or I2C resources are used. A table is provided below
NAME________________________GPIO__________________I2C_Address
Any links to to any relevant documentation are always appreciated Thank you
Hello,
the downloads section has the PCB where you find the below info:
| Pin | GPIO | |
|---|---|---|
| Relay1 | 32 | GPIO12 |
| Relay2 | 16 | GPIO23 |
| Relay3 | 12 | GPIO18 |
| Relay4 | 36 | GPIO16 |
| Pin | GPIO | |
|---|---|---|
| SDA | 3 | GPIO02 |
| SCL | 5 | GPIO03 |
BME Sensor I2C address: 0x76
From line 27:
| PIN NO. | SYMBOL | DESCRIPTION |
|---|---|---|
| 1, 17 | 3.3V | Power positive (3.3V power input) |
| 2, 4 | 5V | Power positive (5V power input) |
| 3, 5, 7, 8, 10, 12, 13, 15, 16 | NC | NC |
| 6, 9, 14, 20, 25 | GND | Ground |
| 11 | TP_IRQ | Touch Panel interrupt, low level while the Touch Panel detects touching |
| 18 | LCD_RS | Instruction/Data Register selection |
| 19 | LCD_SI / TP_SI | SPI data input of LCD/Touch Panel |
| 21 | TP_SO | SPI data output of Touch Panel |
| 22 | RST | Reset |
| 23 | LCD_SCK / TP_SCK | SPI clock of LCD/Touch Panel |
| 24 | LCD_CS | LCD chip selection, low active |
| 26 | TP_CS | Touch Panel chip selection, low active |
