# 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 either connect the
# Thermopile Shield to your OpenMV Cam or an I2C EEPROM to your OpenMV Cam.

mem = i2c.mem_read(256, 0x50, 0)  # The eeprom slave address is 0x50.
