MCP2210 EVALUATION KIT USER’S GUIDE Chapter 2. Installation and Operation 2.1 INTRODUCTION The MCP2210 Evaluation Kit is designed to demonstrate the device as a USB-to-SPI (Master) bridge solution. The Evaluation Kit is comprised of two boards that have the following features: • MCP2210 Breakout Board: - Small plug-in board with DIP form factor (0.6 inches overall row spacing between pins) - Mini-USB connector - Access to the SPI bus and all GP signals - PICkit™ Serial Analyzer compatible header - 3.

MCP2210 Evaluation Kit User’s Guide 2.3 BOARD OPERATION The MCP2210 device is detected by a Windows®-based PC host as a Human Interface Device (HID). The accompanying software can be used to exercise the Evaluation Kit’s features. It also provides a reference point for users that want to create custom applications based on the MCP2210. 2.3.1 MCP2210 Breakout Board Operation The MCP2210 Breakout Board can be used with either the provided motherboard, or as a stand-alone USB-to-SPI (Master) bridge module.

Installation and Operation FIGURE 2-1: SPI TERMINAL UTILITY WINDOW SPI user data section GP Settings Section HEX/Decimal user data mode SPI Transfer Parameters Section Status messages Transfer Data button GP Direct Settings section After the application is started, the state of the connection with the MCP2210 is shown in the Status Messages bar (in the lower left corner of the screen). The user can establish the GP configuration. The GPs can be used as chip select pins.

MCP2210 Evaluation Kit User’s Guide A simple test using the SPI Terminal utility shows how the MCP23S08 (an 8-bit I/O expander) uses the GP4 pin of the MCP2210 device as a chip select line. This line should be active low. The GP4 must be set as in the Figure 2-1, with the IDLE option checked (IDLE value is logic ‘1’) and the ACTIVE option unchecked (ACTIVE value is logic ‘0’).
