Implementing a Single-Chip Thermocouple Interface with the MSP430x42x

说明

• Application circuit describes and shows how to implement a single-chip thermocouple interface without using the signal conditioning circuitry normally required for thermocouples. The thermocouple interfaces directly to the MSP430F42x devices from Texas Instruments, Inc. The MSP430 uses its internal 16-bit sigma-delta ADC to convert the thermocouple readings to a digital value, convert them to temperature and display them on an LCD. A complete schematic and code listing are given at the end of this report
