  1. HMI System for Solar Powered Race Car Eugene Gordon Mohit Mendiratta Jevon Raghubir March 14, 2011 ECE 4007L01 - Dr. Whit Smith

  2. Design and create HMI system for solar vehicle • Implement in Solar Jackets' solar car for World Solar Challenge •  Expected Cost: $260 Project Overview ECE 4007L01 - Dr. Whit Smith

  3. Display vital car and motor information • Create an API for other Solar Jacket groups •  Focus on driver Design Objectives ECE 4007L01 - Dr. Whit Smith

  4. Design Illustration ECE 4007L01 - Dr. Whit Smith

  5. SBC (TS-7250) ECE 4007L01 - Dr. Whit Smith

  6. USB-to-GPIO (UM 245R) ECE 4007L01 - Dr. Whit Smith

  7. LCD (DOGM-128) ECE 4007L01 - Dr. Whit Smith

  8. Example Speed Displays ECE 4007L01 - Dr. Whit Smith

  9. Functions A (Speed, Temp, Battery, etc.) Functions B (PutText, PutBar, PutNeedle, etc) Convert to software Bitmap Put Bitmap on USB from SBC Put Bits on LCD from USB Protocol Stack ECE 4007L01 - Dr. Whit Smith

  10. Communication with SBC • Issues setting up USB drivers • Ran C code on SBC • Set up Linux environment • Crosstool for TS-7250 • Established API concept Project Status ECE 4007L01 - Dr. Whit Smith

  11. Acceptance Testing • Confirmation of SBC functionality • Transfer files via HyperTerminal • Executed simple C programs on SBC • Confirmation of USB-to-GPIO recognition • Confirmed USB recognition on the SBC, yet no native driver can be assigned for communication ECE 4007L01 - Dr. Whit Smith

  12. USB-to-GPIO module communication • 03/18/2011 • C function to bitmap (in software) speed display • 03/31/2011 • PCB Construction • 04/08/2011 • Functionality Testing • 04/15/2011 Milestones ECE 4007L01 - Dr. Whit Smith

  13. Cost Analysis ECE 4007L01 - Dr. Whit Smith

  14. Questions? ECE 4007L01 - Dr. Whit Smith
