| Abstract: | In order to ensure the precision of sampling many signals, a four-channel 12 Bit parallel/serial ADC ADS7824 is used in the data-collecting system of temperature, pressure, rotating speed in the hydraulic experiment bench. Its interface circuits and its part reading/writing program are given. Practice has proved: many signals collecting system composed of ADS7824 feature a smaller volume, higher precision, faster conversion, lower cost, better universality , and more flexible use. It works better for instruments and experiment benches with many input signals. |
