Weekly Progress
My group make smart refrigerator,so that my group must
microcontroller.My group will use microcroller,type is PIC becaues in
the future must learn PIC.PIC can use with my work and use to easy.
PIC is a family of modified Harvard architecture microcontrollers made
by Microchip Technology, derived from the PIC1650.Originally
developed byGeneral Instrument's Microelectronics Division. The name
PIC initially referred to "Peripheral Interface Controller".PICs are
popular with both industrial developers and hobbyists alike due to their
low cost, wide availability, large user base, extensive collection of
application notes, availability of low cost or free development tools, and
serial programming (and re-programming with flash memory) capability.

Engineering Analysis
Strong Point
-Built in oscillator with selectable speeds.
-Small instruction set to learn.
-Inexpensive microcontrollers.
Week Point
-The hardware call stack is not addressable, so preemptive task
switching cannot be implemented.
-One accumulator.
Next Week Job
-Learn about working and address for microcontroller type PIC.
