2. AGENDA Project Background Design Specifications FAST Diagram Conceptual Design Proposed Design PCB Process Proposed Budget Team Management

3. PROJECT BACKGROUND DRV8412 Motor Driver Card – New Texas Instruments product, not yet released – DRV8412 functionality On-board DACs, PWM amplifiers, and current sensors 100-pin DIMM interface

4. PROJECT BACKGROUND C2000 Motor Control Card – C2000 microprocessor family High performance 32-bit microcontrollers – Piccolo C2000F28035 used on chip 16 ADCs Programmed through Code Composer Studio using USB interface with UART protocol – Some motor control code available on TI ControlSUITE

5. PROJECT BACKGROUND C2000 Motor Control Card Schematic

6. PROJECT BACKGROUND C2000 Motor Control Card PCB Layout

7. DESIGN SPECIFICATIONS Redesign C2000 Motor Control Card – Utilize the MSP430 microprocessor family Ultra-low power consumption 16-bit microcontrollers Program MSP430 Motor Control Card – Spin and control brushed DC motors as well as stepper motors Documentation – Commented source code – User guides featuring application notes

9. CONCEPTUAL DESIGN

10. PROPOSED DESIGN MSP430F5435 – 80-pin LQFP (low-profile quad flat package) pin package, just like Piccolo C2000F28035 Minimize redesign – Less flash memory than MSP430F5437 Unused in software implementation – 12 ADCs

11. PROPOSED DESIGN Chosen MSP430 has same pin package – However, significantly different footprint Remap C2000 pins to MSP430 equivalent pins – Two microprocessor families are not functionally equivalent

12. PROPOSED DESIGN Redesign and fabricate PCB – Route connections appropriately within PADS Program MSP430 through CCS – Different software packages available IQ Math package not available for MSP430

13. PCB PROCESS Plan to use Hughes Circuits, Inc. – Integrated PCB fabrication and assembly Required for a price quote – Gerber files, schematic, assembly drawings, Bill of Materials, footprint data sheets
