water temperature control system uses the Single Chip Microcomputer to carry on temperature real-time gathering and controling. DS18B20, digitized temperature sensor, provides the temperature signal by "a main line". In -10～+85℃ the scope, DS18B20’s inherent measuring accuracy is 0.5 ℃. The water temperature real-time control system uses the electricity nichrome wire carring on temperature increiseament and operates the electric fan to realize the temperature decrease control. The system has the higher measuring accuracy and the control precision, it also can complete the elevation of temperature and the temperature decrease control.
The MPC8280 is a versatile communications processor that integrates on e chip a high-performance
PowerPC™ RISC microprocessor, a very flexible system integration unit, and many communications
peripheral controllers that can be used in a variety of applications, particularly in communications and
networking systems
PCI.VHD, THE INTERFACE MODULE WITH PCI AGENT CHIP
--v1.0: For CY7C9689, First Version working on L01A chip
--V2.0: For simplified PCI Agent, Xilinx and AMD chips
The P89LPC938 is a single-chip microcontroller, available in low cost packages, based on
a high performance processor architecture that executes instructions in two to four clocks,
six times the rate of standard 80C51 devices. Many system-level functions have been
incorporated into the P89LPC938 in order to reduce component count, board space, and
system cost.
