Using MAX1457, 27C64 each one piece,and matching a piezoresistive pressure sensor will constitute a pressure measurement module.N pieces ofpressure measurement modules and microcomputers, digital voltmeters canform the bus high precision pressure testing system based on SPI . The circuit is shown in diagram. It is a testing system composedof 6 transmissions, including two power lines, a simulation voltage output line, and three SPI interface lines. In addition, the multi-channel switch choosesmeasuring module andread-only memory through the MCS, ECS lines respectively.
