# 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, ESP32-C or ESP32-H 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 [datasheet of the MPU9250 sensor](https://invensense.tdk.com/wp-content/uploads/2015/02/PS-MPU-9250A-01-v1.1.pdf).
|
||||||
|
|
||||||
|
#### 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 de-initialized successfully
|
||||||
|
```
|
||||||
|
|
||||||
|

This directory is intended for project header files.
|
|
||||||
|
|
||||||
A header file is a file containing C declarations and macro definitions
|
|
||||||
to be shared between several project source files. You request the use of a
|
|
||||||
header file in your project source file (C, C++, etc) located in `src` folder
|
|
||||||
by including it, with the C preprocessing directive `#include'.
|
|
||||||
|
|
||||||
```src/main.c
|
|
||||||
|
|
||||||
#include "header.h"
|
|
||||||
|
|
||||||
int main (void)
|
|
||||||
{
|
|
||||||
...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Including a header file produces the same results as copying the header file
|
|
||||||
into each source file that needs it. Such copying would be time-consuming
|
|
||||||
and error-prone. With a header file, the related declarations appear
|
|
||||||
in only one place. If they need to be changed, they can be changed in one
|
|
||||||
place, and programs that include the header file will automatically use the
|
|
||||||
new version when next recompiled. The header file eliminates the labor of
|
|
||||||
finding and changing all the copies as well as the risk that a failure to
|
|
||||||
find one copy will result in inconsistencies within a program.
|
|
||||||
|
|
||||||
In C, the usual convention is to give header files names that end with `.h'.
|
|
||||||
It is most portable to use only letters, digits, dashes, and underscores in
|
|
||||||
header file names, and at most one dot.
|
|
||||||
|
|
||||||
