Signal input of the one low level rank signal to next driving mainboard.At this point, due to the signal input of first driving mainboard 2
21 are presented high level because directly being connect with system controller 1, and system judges only first driving master after a short time
Plate 2 belongs to high level, therefore the driving mainboard 2 accounts for No.1 sequence automatically.The signal output 24 of first driving mainboard 2 later
Signal input 21a of the high level signal to next driving mainboard 2a is exported again, and next driving mainboard 2a is received once
It is unchanged again in a bit of time just to account for No. two sequences automatically after variation, while its signal output 24a exports a high level-
Low level rank-high level signal give next one driving mainboard, and so on complete driving mainboard sequence.
After the completion of the sequence of each driving mainboard, which sequentially reads the control mould of each driving mainboard
Block 3 assigns each control module 3 address, the ordering action of control module 3 in each driving mainboard is completed, for reading and writing later
The foundation of message address.
The control module data handled on the driving mainboard in addition, each driving mainboard can respectively divide the work, can be effective
Saving processing time.The present invention is passed using chip controls signal (Chip Select, CS), clock signal (CLK) and data
Defeated signal (DATA) drives the signal transmission of mainboard and each control module to control.The driving mainboard passes through chip controls signal
After selecting control module, detection signal is read from the control module by 4 end of external sensor according to clock signal phase sequential
One instruction of these detection signals or transmission.
