# Example for `mp2660` driver

## What it does

It reads all registers from IC

## Wiring

Connect `SCL` and `SDA` pins to the following pins with appropriate pull-up
resistors.

| Name | Description | Defaults |
|------|-------------|----------|
| `CONFIG_EXAMPLE_I2C_MASTER_SCL` | GPIO number for `SCL` | "22" for `esp32`, `esp32s2`, and `esp32s3` |
| `CONFIG_EXAMPLE_I2C_MASTER_SDA` | GPIO number for `SDA` | "21" for `esp32`, `esp32s2`, and `esp32s3` |
