USER MANUAL MCP3221 Microchip

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.
- Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.
- There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
- Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

This chapter provides an overview of the MCP3221 PICtail™ Demo Board and covers the following topics:

• What is the MCP3221 PICtail™ Demo Board?
• What the MCP3221 PICtail™ Demo Board Kit Includes

1.2 WHAT IS THE MCP3221 PICTAIL™ DEMO BOARD?

The MCP3221 device is a low-power, 12-bit A/D Converter (ADC) in a SOT-23 package. It communicates via an I ^2 C ^TM interface.

A stand-alone demonstration is possible using a USB port and the DataView™ software. The MCP3221 PICtail™ Demo Board is also used to evaluate and demonstrate the MCP3221 device using the PICkit™ 1 Flash Starter Kit.

1.3 WHAT THE MCP3221 PICTAIL™ DEMO BOARD KIT INCLUDES

This MCP3221 PICtail™ Demo Board Kit includes:

• The MCP3221 PICtail™ Demo Board (with MCP3221 installed)
- A USB Cable
• MCP3221 DataView software
- Analog and Interface Products Demonstration Boards CD-ROM (DS21912)

- MCP3221 PICtail™ Demo Board User's Guide (DS51545)

NOTES:

Chapter 2. Installation and Operation

2.1 INTRODUCTION

The MCP3221 PICtail™ Demo Board is designed to demonstrate Microchip Technology's MCP3221 device performance with the DataView software, a Personal Computer (PC) GUI, by way of the USB port. A mechanical potentiometer and a prototype area are used as the optional input sources to the device. This demo board can be used to demonstrate firmware development to the MCP3221 device using the PICkit™ 1 Flash Starter Kit.

This board is designed to evaluate the MCP3221 with minimum PCB noise. It uses a two-layer board with both analog and digital ground planes. The circuit schematic and layout have been carefully considered such that the user can evaluate true 12-bit performance using a simple PC USB power supply.

2.2 FEATURES

The MCP3221 PICtail™ Demo Board has the following features:

• Allows simple evaluation of device performance using USB interface and DataView software
• On-board PIC16C745 USB for DataView communication
• Data is displayed in an easy-to-read format complete with data-logging
• Easy to interface to PICkit™ 1 Flash Starter Kit evaluation system
• Simple DC signal generation using mechanical potentiometer

2.3 GETTING STARTED

The MCP3221 PICtail™ Demo Board is used for evaluation and demonstration of the PGA's features. A block diagram of the demo board layout is shown in Figure 2-1. The following procedure describes how to operate this demo board.

1. Install and run the GUI from the PC.
2. Connect the MCP3221 PICtail™ Demo Board to a PC using a USB cable.
3. Use jumper JP1 to select the mechanical potentiometer.
4. The ADC output code will be graphically displayed on the PC.

2.4 MCP3221 PICTAIL™ DEMO BOARD DESCRIPTION

The major components of the MCP3221 PICtail™ Demo Board are listed.

1. MCP3221 device (U1)
2. PICmicro ^® MCU – PIC16C745 (U2)
3. PICkit™ Starter Kit Header (J1)
4. USB Connector (J2)
5. Analog Input and Prototype Area (TP)
6. Input Selection Jumper (JP1)
7. Potentiometer Input (VR1)

For more detailed circuit information, refer to Appendix A. "Schematic and Layouts" and Appendix B. "Bill Of Materials (BOM)".

TP1 JP1 U1 MCP3221 PIC16C745 U2 USB J2 J1 PICKIT™ Starter Kit Header

FIGURE 2-1: MCP3221 PICtail™ Demo Board Block Diagram.

2.4.1 Hardware Power

The USB power is regulated and filtered before supplying power to the MCP3221 device. The raw USB power supplies the digital voltage to the PICmicro MCU only. This digital power supply is filtered through the LRC circuit and the 4.1V regulator as it becomes the analog voltage ( A_VDD ) for the MCP3221. This analog power supply is also used as the reference for the mechanical potentiometer. This regulated ratiometric connection achieves superior performance from the typically noisy PC USB power supply.

2.4.2 MCP3221 Interface to PICkit™ 1 Flash Starter Kit

The MCP3221 is an infrared device. The two data lines, SCL and SDA, are connected from the PICkit Starter Kit header J1 to the appropriate port pins, RC0 and RC1. +5V and V_SS are the other two PICkit Starter Kit connections made on the MCP3221 PICkit header.

2.4.3 Selecting The Analog Input

The MCP3221 analog input is tied directly to TP1, next to a small area for prototyping. A mechanical potentiometer is also connected to this node, allowing for a quick DC evaluation of the device's function. When the jumper is selected, the wiper of the mechanical potentiometer is connected to the analog input of the device. When the jumper is de-selected, the analog input is connected only to TP1 and the prototype area.

2.4.4 Reading the MCP3221 Output Using the DataView Software GUI

The DataView software displays the digital output of the MCP3221 ADC in a graphical format on any Windows ^® compatible PC. Through the USB port, each 12-bit word is transferred from the MCP3221 to the PC, converted to decimal and then plotted on the graph shown in Figure 2-2. Each consecutive conversion is added to the right side of the graph. The y-axis of the graph displays the output codes that have been collected and automatically scales for any given output code range. The x-axis of the graph automatically scrolls to the left once the entire graph has been filled with samples.

FIGURE 2-2: DataView Software Output.

2.4.5 Using the Data Logging Feature of the DataView Software

The DataView software can be used to record MCP3221 conversion data and then to save to a ASCII text file by selecting "File >> Save Data" from the Program menu. The frequency of conversion and subsequent data log is user-selected under "Device >> Configure" from the Program menu. Here the number of samples and polling interval is selected. Please note the polling interval refers to the PC to PICmicro MCU polling interval, not the PICmicro MCU to ADC sample rate.
