Introduction
The CY8CKIT-007 PSoC® 3 Precision Analog Voltmeter Demo Kit showcases PSoC's 20-bit Delta
Sigma Analog to Digital Converter. This kit contains a PSoC CY8C3866, which is connected to
voltmeter leads and a precision reference (in this case a thermocouple).
The kit has the following features:
■
20-Bit High Precision Delta Sigma ADC.
■
Input DC Voltages Range from -30V to 30V.
■
Type K Thermocouple.
■
CapSense Button to Select Between Sources: Voltmeter Leads or Thermocouple.
The kit operates from a pack of two AA batteries (which is included in the kit). The measurement is
displayed on the segment LCD, which is directly driven by the PSoC device. PSoC provides superior
integration and high precision analog for the most demanding customer applications.
The CY8CKIT-007 PSoC 3 Precision Analog Voltmeter Demo Kit is based on the PSoC 3 family of
devices. PSoC is a Programmable System-on-Chip platform for 8-, 16-, and 32-bit applications and
combines user programmable 20-bit precision analog and digital logic with a high-performance 8051
single cycle per instruction pipelined processor achieving 10X the performance of previous 8051
processors. With this PSoC you can create the exact combination of peripherals and integrated
proprietary IP to meet the needs of their applications. You are no longer constrained by what you can
find in a catalog.

Kit Operation
The CY8CKIT-007 PSoC 3 Precision Analog Voltmeter Demo Kit demonstrates the precision of the
CY8C3866 Delta-Sigma 20-bit ADC. It measures an external voltage with range of -30V to +30V.
This kit can also measure the voltage of a thermocouple sensor generated by the different
temperature of the two terminals. The measurement is displayed on the LCD continuously at a rate
of 2.08 Hz. The thermocouple is used for precision reference and showcases the 20-bit resolution of
the ADC. It does not measure temperature. Users can implement temperature measurement
depending on their design-specific requirements.

Kit Operation
2.1
Power Supply
The Voltmeter kit is powered through a USB connector from a pack of two AA batteries.
How to connect:
1. Switch SW1 to the USB position (right).
2. Connect the USB mini-B connector attached to the AA battery pack to the USB female connector
on the board.
Refer to 3.4 Power Supply Options for different power supply options.
2.2
Voltmeter Measurement
1. After you connect the power, D1 LED is ON. The LCD displays the firmware version number
briefly and the voltmeter measurement begins.
2. To reset the Voltmeter reading to ZERO, touch and hold the SOURCE button CSB1 for more than
2 seconds.
2.3
Thermocouple
1. To switch the voltage source between the Voltmeter and Thermocouple, touch and release the
SOURCE button CSB1 quickly. When thermocouple is selected, D2 LED is ON. The
thermocouple measurement is not in temperature unit. It provides high resolution relative voltage
measurement on the thermocouple output.
2. To reset the offset of the thermocouple reading to ZERO, touch and hold the SOURCE button
CSB1 for more than 2 seconds. You touch the tip of the thermocouple with a hot object or hand.
The display shows the change of the temperature in a relative high resolution in voltage.

System Block Diagram and Theory of System Operation
A single CapSense® button is used to select the signal source. The LEDs D1 and D2 are used to
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.

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.

Note: TL_BIAS = Vdd /2
The differential input of the resistor networks is:
= (V1 - V2) / (K+1)
where K=1M / 34.8k = 28.74.
The resistor network successfully divides the input by a ratio of (28.74+1) = 29.74.

Firmware
The design is based on PSoC 20-bit Sigma Delta ADC with differential input selected from either
voltmeter or thermocouple input. An LED is used to indicate the source of the ADC signal. The
firmware keeps reading the ADC input and outputting the value at the LCD. PSoC also monitors the
SOURCE button continuously for user selection of the source and zero the offset of the
thermocouple. Zero point calibration is to make the LCD output to display ‘0’ and get the offset to add
to the further voltage reading. Thus, the final voltage displayed will be equal to actual voltage added
to the zero point offset. The LCD displays Null for zero point calibration when the button is pressed
more than two seconds.

Firmware
4.1
ADC_DelSig
The Delta-Sigma ADC is the core component used in the Voltmeter. The ADC is used to sample an
input voltage, takes the voltage from the Voltmeter mini-hook leads or thermocouple. Because the
ADC is used to sample a differential input, the count returned is a 2's complement, 32-bit value. The
count is then converted to a voltage value by the Voltmeter firmware.

Analog Multiplexer (InputSourceMux)
The ADC samples a differential input provided by the two analog multiplexers. Output of
InputSourceMux1 is connected to +ve input of the ADC and InputSourceMux2 output is connected to
-ve input of ADC. The input to multiplexers can be selected between two voltage inputs: voltage
probes or a thermocouple.

Opamp
The opamp is used to provide a reference for the ADC. It uses the internal reference Vdda/2 in follower mode. The opamp output is routed to port 3, pin 7, which is a common-mode reference for the
voltmeter probe inputs.

Segment LCD
The segment LCD component is used to display the voltage values computed by the voltmeter software. The component provides all analog and digital signals necessary to drive a thirty two segment,
eight digit liquid crystal display using four common lines and thirty-two segment drive lines. As a
stand-alone meter, this is the only output mechanism provided.
