cs_mipi_i2c.sh Shell scripts usage

Introduction

The cs_mipi_i2c.sh script is a toolset for configuring CS-MIPI-X series cameras through the I2C.

RaspberryPi Only, Set IO config

Include the following files,camera_i2c_config、i2c_read、i2c_write、cs_mipi_i2c.sh.

Running

./enable_i2c_vc.sh

./camera_i2c_config

first,it will config IO pin. Then you can run cs_mipi_i2c.sh.

camera_i2c_config USAGE

  • for standard RPI, just run

./camera_i2c_config

  • for RPI Computer Module

./camera_i2c_config [cameranum]
