Pixhawk/Arduino - Read/Write Discrete Data using SPI

[kylehl]

Prerequisite Issues: TBD Followup Issues: TBD Related Issues: #47 #48 #85

Summary

After attempting to connect Pixhawk to Arduino system using UART, we will attempt a secondary method by using SPI as our serial communication protocol.

Terminal Objectives

• Send Pixhawk data to Arduino Due and receive data as necessary using SPI.

  Enabling Objectives

• Add a custom module to the Pixhawk environment that outputs sensor data on a repeating basis using SPI
• Rebuild the Pixhawk environment with your custom module
• Upload the compiled code to the Pixhawk
• Verify that your code works by reading the output data
• Write Arduino SPI code for Due to receive data properly and pass to data management

Need to buy female-female or female-male wires to connect between Pixhawk and arduino
