Degree.
It is as follows the step of the processing method of signal transacting and the single-chip microcomputer in operation module 3 in the step D：
After step S1, program bring into operation, first carry out each module initialization of system and assign initial value to each parameter；
Step S2, signal transacting and operation module 3 judge whether synchronizing signal is high level, when synchronizing signal is not high electricity
Usually, program waits and repeats synchronizing signal state, when synchronizing signal state is high level, into the next of synchronizing signal
Judge sentence step S3；
Step S3, when synchronizing signal not be low level when, program waits and repeats synchronizing signal state, when synchronizing signal shape
When state is low level, step S4 is transferred to；
Step S4, signal transacting and operation module 3 read in ambient light and shine strength signal；
Step S5, signal transacting and operation module 3 are handled the signal data that remote control module is sent again；
The remote control one that the present invention is used has shared six press keys：Red key, green key, Huang Jian, Lan Jian, F1 key and F2 keys,
Parameter during remote control signal receiver corresponding to these buttons is respectively：CH=1, CH=2, CH=3, CH=4, m=1, m=2, CH is mould
The parameter of formula conversion, m is brightness regulation parameter.Assign initial value CH=0, m=0.Hot key, green key, Huang Jian, Lan Jian are not pressed
