MCP2210 Breakout Module User’s Guide
2.3
BOARD OPERATION
The MCP2210 will be detected by a Windows PC host as an HID device. The
accompanying software can be used to exercise the MCP2210 Breakout Module’s
features and also provides a reference point for users that want to design their own
applications based on the MCP2210 device.
2.3.1
MCP2210 Breakout Board Operation
The MCP2210 Breakout Module can be used as a stand-alone USB-to-SPI (Master)
bridge module. The breakout board provides all the signals required to assist the user
in building their boards with the MCP2210.
The board has the following features:
• SPI bus signals (MOSI, MISO, SCK)
• Nine GP signals that can be configured for:
- GPIO functionality (digital input or output pins)
- Chip Select functionality (working with the SPI bus signals)
- Dedicated function pins
• Jumper selectable power supply: 3.3 or 5V (up to 500 mA)
• PICkit™ Serial Analyzer header using GP4 pin as Chip Select signal
Note:
This function is available only on SPI operations, it does not work on I
2
C or
UART signals.
• DIP form-factor (0.6 inches overall row spacing between pins)
By using the provided software and libraries, the user can create personalized PC
applications, using the breakout board as a USB-to-SPI (Master) bridge adapter.
2.3.2
MCP2210 Utility
The MCP2210 Utility software was created for custom device setting requirements. A
few of the settings that this utility can alter include VID, PID, power requirements, and
string descriptors. A download link for this software can be found on the board web
page. For instructions on the use of this software, refer to the software’s supporting
documentation included within the application install package.
2.3.3
SPI Terminal Utility
The SPI Terminal Utility is a tool that allows low-level data exchange at the SPI bus
level. This application is useful for low-level communication and troubleshooting
between the MCP2210 and various SPI slave modules.
The utility window has different sections for GP designation, SPI transfer parameters
and user data areas.
