# I2C Control

# This example shows how to use the i2c bus on your OpenMV Cam by dumping the
# contents on a standard EEPROM. To run this example connect an I2C EEPROM
# to your OpenMV Cam (P4 = SCL, P5 = SDA).

from machine import I2C

i2c = I2C(2)  # The user-accessible i2c bus is bus 2 on the OpenMV N6.
print(i2c.scan())  # 显示已连接的设备。
mem = i2c.readfrom_mem(0x50, 0, 256)  # The eeprom slave address is 0x50.

print("\n[")
