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

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

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

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

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
