Embedded systems

Design & Implementation of Compact Flash Memory Card Interface to a Mobile Data Logger to meet specifications: huge PC-readable data (FAT file system, ~ 1GB) storage on CF card, Data transfer rate 10 Mbytes/sec, Data reliability around 1 error per 10 billion bits, and low power consumption to ensure all data being stored on CF card when the data logger supply power is failed. This project is done under order by Munich Microfuzzy Company, Germany.

Research works related to Intel microprocessor PXA 255, IDE-mode CF card, FAT file system, Linux OS Sympian, C++ coding were experienced.

 
Design and build a Versatile Drilling Machine with required specifications: PCB board is able to be automatically drilled as seen on computer, and any 2-D simple picture created on computer can be drilled. Studied and applied microcontroller, C/Assembly programming, PC-microcontroller communication and layout drawing tool. This project is done with the first prototype with drilling function in 2002 and will be in the second phase started from 2009.
