Connecting the SPI Interface

SECTION 2.2

Connecting the SPI Interface

The SPI (Serial Peripheral Interface) is the com- munications and configuration interface.

For prototyping we recommend the purchase of the parameter setup cable MD-CC300-000. Use of this cable requires the adapter MD- ADP-M23.

For more information on prototype develop- ment cables, please see Appendix: E: Prototype Development Cables.

SPI Signal Overview

+5 VDC (Output)

This output is a voltage supply for the setup cable only. It is not designed to power any external devices.

SPI Clock

The Clock is driven by the Master and regulates the flow of the data bits. The Master may transmit data at a variety of baud rates. The Clock cycles once for each bit that is transferred.

Logic Ground

This is the ground for all Communications.

MISO (Master In/Slave Out)

Carries output data from the MDriveAC Plus Microstepping units back to the SPI Master. Only one MDriveAC Plus MicroDrive can transmit data during any particular transfer.

CS (SPI Chip Select)

This signal is used to turn communications to multiple MDriveAC Plus Microstepping units on or off.

MOSI (Master Out/Slave In)

Carries output data from the SPI Master to the MDriveAC Plus Microstepping.
