基于MSP430F42X的单芯片热电偶接口
ABSTRACT
This application report 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.
