Universal embedded marker and marking method based on CCP

An embedded universal calibration device and method based on CCP protocol is disclosed. Said device is composed of a high-level calibrating tool running on PC for displaying the parameters to be monitored in ECU and sending commands to low-level unit, and a low-level unit running on the ECU to be calibrated for receiving the commands, executing the relative actions, returning the answer, and periodically sending the parameters to be monitored. Said high-level calibrating tool and low-level unit are connected via USB, CAN interface and CAN bus and the CN packets are used to calibrate and monitor the parameters in ECU.
