Hardware
System Block Diagram and Theory of System Operation
A single CapSense
indicate the selected signal source between the Voltmeter and Thermocouple respectively.
CY8C3866 drives the LCD segment directly without external driver. The voltmeter or thermocouple
data is displayed on a 8 digit LCD, which is driven directly by the CY8C3866 itself.
Figure 3-1. Voltmeter Kit Block Diagram
In the voltmeter input, a resistor network is used to scale down the voltage to suitable input voltage
for the Delta Sigma ADC. TL_BIAS is from PSoC internal voltage reference source of Vdd/2. It
provides a bias to the circuit so that it can accept negative voltage.
