Problems solved by technology

[0005] The system and method deficiency of the dynamic configuration IIC address described in the above-mentioned patents are that each slave must execute the i=i+1 calculation program inside its microprocessor simultaneously, keep the synchronization in time, and wait with timing as i= condition of i+1
Therefore, the program will take a long time to maintain the reliability of the address configuration

Embodiment Construction

[0045] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0046] The method for automatically configuring multiple slave addresses in the system of the present invention can be applied to a system composed of one master and N slaves. Due to communication needs, each slave in the system needs to be configured with an address uniquely identified in the system.

[0047] A method for dynamically configuring addresses, the software flow chart is as follows figure 1 shown, including the following steps:

[0048] S31 dynamic configuration address system power-on initialization, the output port (OUT) of the master and the output port (OUTP) of each slave are set to "0" or "1";

[0049] S32 The microprocessor of the master in the dynamic configuration address system sends address data to the input port (INP) of the microprocessor of the slave 1 in the system through the output port (OUT) and the address configuration ...

Abstract

The invention provides a method for dynamically allocating a plurality of slave addresses of a system and the system thereof. The method comprises the following steps: a slave of the system firstly determines a native address and generates an address data of the next slave which is sent to the next slave; the next slave allocates the native address according to the received address data and generates the address data of the next slave which is sent to the next slave; the steps are repeated till all the slaves of the system complete address allocation, and the last slave sends the generated address data of the next slave back to a host computer. The method and the system can be used for allocating address for various bus devices and system composed of a plurality of non-bus devices.

Description

technical field [0001] The invention relates to a method and a system for configuring addresses, in particular to a method and a system for dynamically configuring the addresses of each slave in a master-slave system. Background technique [0002] Patent application number CN200410077281.7 discloses a system and method for dynamically configuring IIC addresses. [0003] A system for dynamically configuring IIC addresses described in this patent includes a host, multiple slaves and an IIC bus, and the host includes a microprocessor and an IIC interface. Wherein, the signal input pin P1 of the microprocessor of each slave is connected to a pull-up resistor, and the signal output pin P7 is connected to the signal input pin P1 of the next slave. [0004] A method of dynamically configuring the IIC address described in this patent is: the master dynamically configures different IIC addresses for each slave by delaying: initializing the count variable i=0; each slave sets the sig...
