A kind of ZIGBEE application module
Technical field
The present invention relates to a kind of ZIGBEE application module.
Background technology
Zigbee is low-power consumption territory based on IEEE802.15.4 standard fidonetFido, the technology specified according to this agreement
It it is the wireless communication technology of a kind of short distance, low-power consumption.This title derives from the eight word dances of Apis, owing to Apis (bee) is
By circle in the air and " drone " (zig) shake wing " dancing " come with companion transmit pollen place azimuth information, say, that honey
Honeybee relies on such mode to constitute the communication network in colony.Be characterized in closely, low complex degree, self-organizing, low-power consumption,
Low data rate, low cost.
The each electronic product in existing market etc. are all subjected to produce and sell, the link such as after sale, during these, right
Mark or differentiation that one circuit board compares are the most necessary, simultaneously because the design of processor is the most powerful now,
Product for different model is likely to have only to a circuit board, it is only necessary to program makes a distinction, and these information are all
Need to be stored in memorizer.Current electronic product produce during, need its panel is identified, need by
Inside parameter read-in memorizer, needing to power on and could write when write, its workload is bigger;Further, since traditional electronics
The failure code of product is also stored in the panel of electronic product itself, and when it breaks down, the detection source of trouble is also ratio
Cumbersome.

Further, described ZIGBEE equipment is ZIGBEE read write line.
Further, described ZIGBEE chip is IIC or SPI communication with the communication modes of outside host control panel.
The present invention is according to the amphicheirality of ZIGBEE chip so that it is can carry out both-way communication, communication with the MCU of electronic product
Mode is IIC or SPI communication, and it both can carry out read operation by MCU to the eeprom memory of ZIGBEE chip, it is also possible to
It is carried out write operation.Outside by aid ZIGBEE read write line, it is also possible to read the data of ZIGBEE storage inside, also
Can write data in ZIGBEE chip, communication modes is ZIGBEE communication.
The present invention is reached to provide the benefit that:
The present invention can realize on-board memory and need not power on, and memorizer can be carried out read/write, save time, save trouble;User can
Read/write operation is carried out, it is also possible to pass through with eeprom memory ZIGBEE module carried by the MCU of equipment panel
ZIGBEE read write line is written and read operation to the EEPROM of ZIGBEE module.
