24. ASIM Device Appliqué Sensor Interface Module Contents: AT90USB1287 Microprocessor 48 input/output pins USB Port Located microprocessor datasheet Unable to locate ASIM datasheet

25. Input/Output Pins 48 total pins Divided into six ports (A…F), each with eight pins (0...7) All ports serve as 8-bit bidirectional input/output ports Only ports D, E, and F are also able to serve external interrupt functions*. No datasheet located, or port labeling of ASIM. Understanding the location of these ports and pins is crucial in the development of C-code. Team used trial and error method to map all input/output ports and pins.

26. ASIM Map Sketch

27. Data Acquisition/Commands The AVR-Studio is useful in initializing ports and pins, and defining them as I/O. Must be used in conjunction with Putty terminal to actively send a command or subscribe to an incoming data source.

28. Future Work  Further understanding of the Putty terminal software, and it’s ties with the AVR-studio and xTEDS.  Datasheets, “.hex” files, “.c” files, and xTEDS that proved useful are stored for use by future teams.  With the help of Joshua Birch, a corrected CubeFlow Manual has been created.
