Jayapandian and Usha Rani Ravi Design Development & Services Section, Materials Science Division Indira Gandhi Centre for Atomic Research, Kalpa Kama 603 102. Tamil Nadu. IndiaABSTRACT This paper describes a single chip embedded temperature controller design programmed in a single Programmable System on Chip (PSoC);a mixed array logic consists of analog,digital and digital communication blocks within in it.The virtual instrument control program written in Labview ver.7.1,a graphical language,provides user friendly menu driven window based control panel,interacts with the single PSoC chip design for sensing and controlling the temperature.This simple cost effective embedded design finds potential application in laboratory as well as in industries.This deign can also be made as a standalone system without PC by programming LED/ LCD display and key pad attachment modules in same PSoC chip.1. INTRODUCTION The advent of intelligent programmable embedded silicon designs provides the ability to implement any required hardware programmatically for the design automation in industries and laboratories.Recent trend in laboratory as well as in industrial automation designs uses minimal hardware and maximum support of software.The programmable embedded components and application software available in the market enables the designer for user friendly cost effective design solution for any system automation.Temperature controllers are playing vital role in industries and laboratories.To accurately control process temperature without extensive operator involvement,a temperature control system relies upon a controller,which accepts a temperature sensor such as a thermocouple or RTD as input.It compares the actual temperature to the desired control temperature,or set point,and provides an output to a control element.The controller is one of the major parts of the entire control system,and the whole system should be analyzed in selecting the proper controller.This paper describes a novel single chip temperature controller design with Cypress Micro systems Programmable System on Chip (PSoC).Virtual instrument control program written in Lab VIEW ver.7.1 interacts with the embedded PSoC design and senses and controls the temperature of furnace / load.2. PROGRAMMABLE SYSTEM ON CHIP (P Soc) While Sand inexpensive interface to sensors,andmore.CypressSystem-Chip(PSoC)architecture offers a flexible,economical solution for a wide variety of applications.This paper describes the design of a temperature controller on a single CY8C27143,8 pin PSoC chip.Ass how n in fig.1,it features four main areas:PSoC core,digital system,analog system,and resources including in/out ports. This architecture allows the user to create customize Alpheratz configurations that match the requirements of each individual application.The UAR Tinter face, coupled with configurable analog and digital peripherals makes the CY8C27143 truly universal in its connections to the external world.The PSoC core includes:an M8C micro controller;32K Bytes of program flash memory;2Kbyte of data RAM;internal 24 oscillator;sleep and watchdog timer;general-purpose input/output pins (GPIO) allowing any pin to be used as digital input or output,and most pins to be used as analog inputs or outputs.Every pin can be used as a digital or analog interrupt.The digital system is made up of 8digital PSoC blocks.Each block is an 8-bit resource that can be used alone or combined with other blocks to form peripherals.Possible peripherals include:PWMs (8- to 32-bit);PWMs with dead band (8- to 24-bit);counters (8- to 32-bit);UART 8-bit with selectable parity;SPI master and slave;cyclical redundancy checker/generator (8- to 32-bit);pseudo random sequence generators (8- to 32-bit).These digital blocks can be connected to any of the GPIO through a series of global buses.These buses also allow for signal multiplexing and performing logic operations.The analog system is made up of12configurable blocks,each comp rising an op amp circuit allowing the creation of complex analog signal flows.Analog peripheral sar every flexible and can be customized to support specific application requirements.Some of the more common PS0C analog functions are:filters (2 and 4 pole band-pass,low-pass,andnotch); amplifiers (up to 2,with selectable gain to 48x);instrumentation amplifiers (1with selectable gain to 93x); comparators (up to 2, with 16 selectable thresholds);DAC (up to 2, with 6 to 10-bit resolution); and SAR ADC (up to two,with 6-bit resolution).In combination with the digital blocks,additional functions can be created, including: incremental ADCs (up to 2, with 6- to 14-bit resolution); delta sigma ADC (1,with 8-bit resolution at62.5ksps).The additional system resources provide additional capability useful for the complete system design.Fig. 1 : Block diagram of Programmable System on Chip (PSoC) internal blocks3. VIRTUAL INSTRUMENT PROGRAM Virtual instrument (VI) is an application of general purpose digital PCs for the measurement and control of various physical variables.The VI program mimics the control processes,which are in a remote area,on the PC screen.On-going process control automation can be visualized by the experimentalist through PC screen.VI program provides inexpensive and yet a powerful platform for the control and data acquisition of process variables.These programs are easy to implement with graphic languages (G-language).The “G” language implements the data flow technique.The usage of “G” language provides easy interfacing with PCs under the Windows environment 2. The “G” language provides built-in function libraries for a variety of application requirements as graphic palettes, which in turn supports the required DLL s for the functions to run under windows environment.Usually the “G” language VI programs consist of two frames viz.,panel diagram and functional diagram.In the panel diagram,programmers can assign various controls and indicators (i.e., input and output variables).their requirements and in the functional diagram, the designers can implement the required.

PSoC SINGLE CHIP TEMPERATURE CONTROLLER DESIGN Fig.2 shows the PSoC designer screen for the embedded single chip temperature controller design project 1.Left side of the screen shows the settings of global resource and user module parameters along with pin connectivity.Middle portion of the screen shows the analog and digital blocks user module placement.Top portion of the screen shows the selected user modules for this project.Right side of the screen describes the pin connectivity configured in the design.In this novel single chip design,thermocouple (TC) signal has been amplified by a programmable gain amplifier (PGA) placed in the PSoCs analog block.The amplified TC signal has been fed in to a 12 bit Analog-to digital(ADC) user module programmed in the PSoC chip, which includes both analog and digital blocks for its functionality by PSoC designer programming.The converted digital data of the TC signal has been fed to the UART user module for serial communication with Personal Computer.The UART user module placed in the chip,automatically gets placed in two digital blocks of PSoC chip,transmitter (TxD) and receiver (RxD) for PCs serial communication.A pulse width modulator (PWM),placed in the PSoC digital block,sets a serial pulse width modulated TTL pulses in response to the PID control function for the deviation in set and measured temperature.This will in turn controls the optically coupled solid state relay (SSR) driving the AC line power connected to the load/furnace3,4.The menu driven window based virtual instrument control program senses the temperature,via,thermocouple,TC amplifier,12-bit ADC and UART communication block of PSoC chip and evaluate the control functions like PID, linear heating, on-sweep and sets the pulse width of PWM in a PSoC chip via UART block in a serial communication. Fig. 3 : Single PSoC chip Temperature controller design Fig.3.shows the connectivity of a single PSoC chip design with solid state relay (SSR)and USB port via,serial-to-USB converter cable for communication with PC.The SSR,acts as AC power controller for controlling the furnace power,has been activated by the PWM pulses from PSoC chip.The menu driven virtual instrument control program works in window environment interacts with the embedded design for sensing,controlling and acquiring the temperature data. On-line plotting of acquired temperature data also carried out by the VI program.5. CONCLUSION A simple and cost effective embedded temperature controller has been designed,fabricated and tested successfully for its functionality.This compact designs permits the user to select any type of control function through its virtual instrument program,written in LabVIEW 7.1,and works under window environment.This design can be directly connected to PCscom port or USB port via USB-to-serial converter cable,the SSR power controller module can be connected on the furnace stand.The optically isolated power controller provides safe operation without damaging the interfacing intelligent controller.6.
