  1. Printed Circuit Board System Block Diagram: Schematic Pin Mapping • Power Supply PCB Layout Vin Min: 3.2V Vin out: 9V Vin Max: 3.4 V Frequency:1600kHz Finite Element Analysis Power dissipation (Q) = Heat transfer coefficient (h) * Surface Area (SA) * (Maximum component temperature (T1) – Air temperature (T2))

  2. Engine Micro Controller Team Members Dean Kooiman, SauravJoshee(Team Leader), Josh Gabler Background The Drivven micro controller was designed to provide an elegant interface to Drivven’s engine controllers. The current interface runs on a computer which has been proven difficult to operate in the field. The micro controller will communicate with Drivven’s engine Controllers over TCP/IP. CalVIEW ® Computer Interface Drivven Engine Controller Engine Test Platform Communication Block Diagram Digi Development Board • Built in Ethernet, Serial, and USB controllers • LCD and VGA Headers • ARM9 Microprocessor • 50 GPIO pins ( but every pin is usable for IO)

  3. Porting the RTX Real-Time Kernel • Integrating the Real-Time Agent module for debugging • Creating the target in LabVIEW and incorporating the Keil toolchain • Developing peripheral and I/O drivers Embedded Design Net OS With ThreadX Fall 2008 Specs • A real time operating system that allows for interruptible GPIO and graphics using C • Provides support for Ethernet and CAN Design • GUI designed with wxWidgets • Interruptible GPIO on switches • Separate threads for graphics and network communication GUI Operation Flowchart Porting to LabView/Keil Spring 2009 Software Support Advantages to LabView • Easy to use graphical programming interface • Much faster because it uses a process flow instead of a timed flow • Don’t have to program GUI in C (wxWidgets) • Portable to another Arm9 board with minimal changes • Subversion: • Simultaneous Development. • Automated code merge, revert. • Keil Debugger with Segger J-Link • LabView Embedded LabView GUI Steps to Porting • Porting the RTX Real-Time Kernel • Integrating the Real-Time Agent module for debugging • Creating the target in LabVIEW and incorporating the Keiltoolchain • Developing peripheral and I/O drivers Important DigiConnectCore 9p addresses
