@ -41,6 +41,13 @@ Under ESP-IDF V5.2 or later, this project uses the new I2C driver, but there is
ESP_ERROR_CHECK(i2c_driver_install(I2C_NUM, I2C_MODE_MASTER, 0, 0, 0));
```
This project allows you to use a mode that does not install i2c drivers.
If you use this mode, you must install the i2c driver before this.
```
i2c_master_init(&dev2, I2C_DRIVER_NOT_INSTALL, I2C_DRIVER_NOT_INSTALL, CONFIG_RESET_GPIO);
```
- New i2c driver
We need to run this code on the first i2c device.
