Communication Protocol on 64-Channel ECVT Data Acquisition System

This research relates to tomography based on capacitance measurement namely Electrical Capacitance Volume Tomography (ECVT). This paper discusses the communication protocols in the 64-channel ECVT data acquisition system (DAS ECVT). The communication protocol is divided into two type, first, communications protocols between the master and slave microcontrollers within the DAS ECVT. The second is the communication protocol between the DAS ECVT and the personal computer (PC). The design of protocol communication is a simple protocol consisting only of headers, command data, end of command (eoc), and enter characters. The speed of the command depends on the speed of the baud rate, the higher baud rate the smaller the total time of command. The maximum baud rate that can be given is 921600 bps with the total time is 159 μs.
