Sponsored by the RIT EE Department

2. Purpose Problem Solution
Senior Design teams panic when it comes to microcontrollers
Solution
Have a powerful evaluation board available to students in order to build quick prototypes, allowing them to modify the design of the board for their final product.

3. Hardware Concepts Recent TI processor (TMS320 series)
28335
2809
2812
Debug input/output
Lights, buttons
WiPort (wireless HTML debug)
Test points

4. TI Processor Digital Signal Processor (DSP) High speed (100MHz)
Use Code Composer to write programs
Already used in the EE curriculum
C or Assembly
More than 32 I/O pins
16 channels of analog-to-digital conversion

5. Wireless Debug
WiPort
TI controller

6. Board Layout Design is for three stackable layers Processor I/O
Test/probe points

7. Documentation Concepts
Board Tutorial
Assumes no previous experience
Documents all features and board layouts
Diagram of processor and I/O boards
How to program the DSP
Application suggestions
Do’s and Don’ts
Extending the design to a new PCB
Schematics and sample code provided on a CD
“Quick start” guide to get user up and running
Correct power input
Connecting LEDs to some GPIO pins
Sample code to flash the LEDs

8. Risk Assessment Risks Risk Mitigation
TI may not release the on time/it may be buggy
If DSP does not work, no way to debug
Learning curve will be too great for end-user
Software documentation is sparse
Initial hardware debug will be difficult
Risk Mitigation
Don’t use the (use 2809 instead)
Connect a voltage and current sensor to WiPort
Provide usable code samples and subroutines
Maintain a relationship with software developers at respective companies, find sample code
Spread initial hardware design onto separate boards

9. Current Status DSP Wireless Debug Documentation (Tutorial and manual)
Hardware concept finalized (TMS320F2809)
No software written yet
Evaluation kit on order
Wireless Debug
Hardware concept finalized (WiPort)
Evaluation board obtained, some software development
Need to obtain replacement
Documentation (Tutorial and manual)
Plans completed
Writing will begin as layout commences
