# I2C Simple Example
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
## Overview
|
||||
|
||||
This example demonstrates basic usage of I2C driver by reading and writing from a I2C connected sensor:
|
||||
|
||||
If you have a new I2C application to go (for example, read the temperature data from external sensor with I2C interface), try this as a basic template, then add your own code.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Hardware Required
|
||||
|
||||
To run this example, you should have one ESP32, ESP32-S or ESP32-C based development board as well as a MPU9250. MPU9250 is a inertial measurement unit, which contains a accelerometer, gyroscope as well as a magnetometer, for more information about it, you can read the [PDF](https://invensense.tdk.com/wp-content/uploads/2015/02/PS-MPU-9250A-01-v1.1.pdf) of this sensor.
|
||||
|
||||
#### Pin Assignment:
|
||||
|
||||
**Note:** The following pin assignments are used by default, you can change these in the `menuconfig` .
|
||||
|
||||
| | SDA | SCL |
|
||||
| ---------------- | -------------- | -------------- |
|
||||
| ESP I2C Master | I2C_MASTER_SDA | I2C_MASTER_SCL |
|
||||
| MPU9250 Sensor | SDA | SCL |
|
||||
|
||||
|
||||
For the actual default value of `I2C_MASTER_SDA` and `I2C_MASTER_SCL` see `Example Configuration` in `menuconfig`.
|
||||
|
||||
**Note: ** There’s no need to add an external pull-up resistors for SDA/SCL pin, because the driver will enable the internal pull-up resistors.
|
||||
|
||||
### Build and Flash
|
||||
|
||||
Enter `idf.py -p PORT flash monitor` to build, flash and monitor the project.
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
## Example Output
|
||||
|
||||
```bash
|
||||
I (328) i2c-simple-example: I2C initialized successfully
|
||||
I (338) i2c-simple-example: WHO_AM_I = 71
|
||||
I (338) i2c-simple-example: I2C unitialized successfully
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
(For any technical queries, please open an [issue](https://github.com/espressif/esp-idf/issues) on GitHub. We will get back to you as soon as possible.)
