It uses a MAX1457 and a 27C64 to match with piezoresistive pressure sensor and constitute a pressure measurement module. N pieces of pressure measurement module with the computer and digital voltmeter form a PI bus high-precision pressure test system circuit. It consists of six transmission lines including two power supply lines (UDD, USS), an analog voltage output line ( out , pick digital voltmeter ) and three SPI interface lines (ECLK, EDI and EDO ).
