Embedded Programmable System on Chip (PSoC) High Resolution Digital Voltmeter

Abstract

This design describes a high resolution Digital Voltmeter embedded design in a single PSoC chip, which can measure wide range of voltages between 1millivolts – 5volts and found suitability in sensor applications. This design is implemented in a PSoC3 device IC CY8C3866. The design implements analog and digital user modules: a buffer, 20 bit ADC, UART and LCD. The ADC gets the analog input from measurement signal or from sensors and the digitized output is sent to serial port through UART module. User friendly menu driven program written in LABVIEW acquires the serial data from PSoC chip and the acquired measurement data is displayed on the PC menu screen as well as saved in a user specified file path. The user interacts only with the graphical screen designed for the project; hence PC is used only as an input-output device.
