PCB Design• Made custom device

libraries for bluetooth module & ATmega164p

• Through-hole components => mostly routed on the back (blue traces)– Also reduces problems

due to no through hole plating

• Stacked bluetooth module & microcontroller to save space

• Uses modular accelerometer board

• External clock source

Python for S60

• Write Python applications for cell phones with S60 platform

• About S60 Platform: - Allows software on cell phones to

run - Provides full-color user interface - Includes software to combine

features of a mobile phone and PDA - Examples: e-mailing, browsing,

calendar, data transfer

Python for S60 (cont.)

• Advantages of Python: - open source - object oriented - extensive standard library - modules can be extended using C or C++ - applications can be written quickly

• Additional Advantages of PyS60: - can create standalone applications - additional modules to access cell phone functions

like camera, audio, and Bluetooth communications
