TC1047A Temperature-to-Voltage Converter PICtail™ Demo Board User’s Guide At this point, the PIC16F676 device is reading the temperature data from the TC1047A and displaying the temperature on the eight red LEDs (D7-D0) on the PICkit 1 Flash Starter Kit board. The ten’s digit of the temperature data is represented by bits D7-D4, with D7 being defined as the Most Significant bit (MSb).

PICkit™ 1 Flash Starter Kit LED Display of 75°F. The temperature display will change when the temperature of the TC1047A is varied. A simple example of this can be seen by pressing your finger on the TC1047A device (U1) on the TC1047A Temperature-to-Voltage Converter PICtail™ Demo Board. More dramatic changes can be seen by applying heat to the TC1047A with a hair dryer or hot air gun, or by cooling the device down.
