CONFIG_I2C_1_DEFAULT_CFG¶

Port 1 default configuration

Type: hex

Help¶

Allows the I2C port to be brought up with a default configuration. This is useful to set if other drivers depend upon using the I2C bus before the application has a chance to custom configure the port. Setting this value does not prohibit the application from customizing the values later. Refer to include/i2c.h file for proper values.

Direct dependencies¶

(I2C_1 && I2C_ESP32 && I2C) || (I2C_1 && !HAS_DTS_I2C && I2C)

(Includes any dependencies from if’s and menus.)

Defaults¶

0x12 if I2C_1 && I2C_ESP32 && I2C
0x0 if I2C_1 && !HAS_DTS_I2C && I2C
