[I2C Tools](https://i2c.wiki.kernel.org/index.php/I2C_Tools) is a simple but very useful tool for developing I2C related applications, which is also famous in Linux platform. This example just implements some of basic features of [I2C Tools](https://i2c.wiki.kernel.org/index.php/I2C_Tools) based on [esp32 console component](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/console.html). As follows, this example supports five command-line tools:
1. `i2cconfig`: It will configure the I2C bus with specific GPIO number, port number and frequency.
1. `i2cconfig`: It will configure the I2C bus with specific GPIO number and frequency.
2. `i2cdetect`: It will scan an I2C bus for devices and output a table with the list of detected devices on the bus.
3. `i2cget`: It will read registers visible through the I2C bus.
4. `i2cset`: It will set registers visible through the I2C bus.

#### Pin Assignment:
**Note:** The following pin assignments are used by default according to `CONFIG_I2C_MASTER_SCL` and `CONFIG_I2C_MASTER_SDA` , you can change them with `i2cconfig` command at any time.
| | SDA | SCL | GND | Other | VCC |
| ------------------- | ------ | ------ | ---- | ----- | ---- |
| ESP32 I2C Master | GPIO18 | GPIO19 | GND | GND | 3.3V |
| ESP32-S2 I2C Master | GPIO5 | GPIO4 | GND | GND | 3.3V |
| ESP32-S3 I2C Master | GPIO5 | GPIO4 | GND | GND | 3.3V |
| ESP32-C3 I2C Master | GPIO5 | GPIO4 | GND | GND | 3.3V |
| ESP32-C2 I2C Master | GPIO5 | GPIO4 | GND | GND | 3.3V |
| ESP32-H2 I2C Master | GPIO5 | GPIO4 | GND | GND | 3.3V |
| Sensor | SDA | SCL | GND | WAK | VCC |
**Note:** You must run the `i2cconfig` command first to setup the I2C bus with proper GPIOs.
**Note:** It is recommended to add external pull-up resistors for SDA/SCL pins to make the communication more stable, though the driver will enable internal pull-up resistors.
### Configure the project
Open the project configuration menu (`idf.py menuconfig`). Then go into `Example Configuration` menu.
- You can choose whether or not to save command history into flash in `Store command history in flash` option.
### Build and Flash
Run `idf.py -p PORT flash monitor` to build and flash the project..

### Check all supported commands and their usages
```bash
==============================================================
| Steps to Use i2c-tools |
| |
| 1. Try 'help', check all supported commands |
| 2. Try 'i2cconfig' to configure your I2C bus |
| 3. Try 'i2cdetect' to scan devices on the bus |
| 4. Try 'i2cget' to get the content of specific register |
| 5. Try 'i2cset' to set the value of specific register |
| 6. Try 'i2cdump' to dump all the register (Experiment) |

### Configure the I2C bus
> [!IMPORTANT]
> You must run the `i2cconfig` command before using other I2C commands.

i2c-tools> i2cconfig --sda=18 --scl=19 --freq=100000
```
* `--port` option to specify the port of I2C, here we choose port 0 for test.
* `--sda` and `--scl` options to specify the gpio number used by I2C bus, here we choose GPIO18 as the SDA and GPIO19 as the SCL.
* `--freq` option to specify the frequency of I2C bus, here we set to 100KHz.
