DS52056A-page 11 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 I2C 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. DS52056A-page 12 © 2012 Microchip Technology Inc. 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 section (lower left corner of the screen). The user can establish the GP configuration. The GPs can be used as chip select pins. Each GP Active and Idle value can be established by selecting the appropriate check boxes, or by directly supplying the correct value in the GP Direct Settings section. The same behavior applies to the GP designation (the GP designation can be established by clicking the appropriate radio button, or by directly supplying the GP designation value in the GP Settings Direct Values section). The SPI settings pertaining to the needed SPI transfer can be established in the SPI Parameters section. The data to be sent goes in the Tx Data field. To send the data to the SPI slave device, click the SPI Transfer Data button on the lower-right side of the screen. The data received from the SPI slave device is displayed in the Rx Data field. The user data can be supplied in either HEX or Decimal mode. This can be accomplished by selecting the HEX mode check box. The data in the Tx and Rx Data fields will be displayed in HEX or Decimal. © 2012 Microchip Technology Inc. DS52056A-page 13 MCP2210 Breakout Module User’s Guide A wider range of tests is available when using this board and the utility software with the MCP2210 Evaluation Kit (ADM00421). This kit allows communication with several SPI slave devices (I/O expander, EEPROM, ADC and temperature sensor). For more details on examples using the SPI Terminal Utility software, see MCP2210 Evaluation Kit User’s Guide (DS52057). 2.4 MCP2210 TYPICAL USAGE SCENARIOS MCP2210 can be used in systems where an SPI bus is available. The MCP2210 can be either the single master on the bus, or one of the masters sharing the bus, if a proper master access arbitration scheme is in place. A typical usage scenario is shown in Figure 2-2, where MCP2210 is the only master on the SPI bus. This links the SPI slave chips in the system, while a few GPs (configured for Chip Select function) can be used as Chip Select lines. If SPI slave interrupt monitoring is required, the GP6 needs to be configured for its dedicated function, in order to monitor the interrupts coming from the SPI slave chips. The PC application will take care of all the details necessary for data transfer between the MCP2210 and the SPI slave chips. FIGURE 2-2: MCP2210 TYPICAL USAGE DIAGRAM MCP2210 USB USB-to-SPI bridge External Interrupt (GP6) SPI bus MOSI, MISO, SCK Chip Select lines CS0-CS8 SPI slave chip #1 Interrupt ... SPI slave chip #n Interrupt When a system requires more than one SPI master that share the same bus, an arbitration scheme needs to be developed, in order to prevent the multiple SPI masters from accessing the bus at the same time. MCP2210 has support for an arbitration mechanism which uses GP7 and GP8 (configured for dedicated pin functionality) for this purpose. DS52056A-page 14 © 2012 Microchip Technology Inc. Installation and Operation When GP8 is configured for its dedicated functionality, the pin can be used as a bus release request for MCP2210 coming from another master. GP7 (configured for its dedicated functionality) is used as an SPI bus release acknowledge signal towards the requesting master. When an external SPI master requests the MCP2210 to release the bus, the device completes the current SPI transfer (or it can be cancelled by the PC application sending the proper USB command), then releases the bus and signals the event on the acknowledge pin (GP7). The second master now has ownership of the bus, and can keep it, as long as the SPI bus request pin (GP8) is kept asserted. By using the dedicated functionality of the GP7 and GP8, the MCP2210 can be used in a multiple SPI master system.
