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

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

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

PROJECT BACKGROUND C2000 Motor Control Card Schematic

PROJECT BACKGROUND C2000 Motor Control Card PCB Layout

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

CONCEPTUAL DESIGN

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

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

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

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
