Engine Micro Controller

BackgroundThe 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.

Porting to LabView/Keil Spring 2009

•A real time operating system that allows for interruptible GPIO and graphics using C•Provides support for Ethernet and CAN

Specs

Design•GUI designed with wxWidgets•Interruptible GPIO on switches•Separate threads for graphics and network communication

Software Support •Subversion: Simultaneous Development. Automated code merge, revert.•Keil Debugger with Segger J-Link•LabView Embedded

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

LabView GUI

•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
