Command execution module C1 receives " at read_reg 0x0B " instruction, calls the register instruction of reading object module and carries out (Fig. 3 step S6).
Calling has the program rreturn value after the register instruction of reading object module is carried out, the convenient description, and suppose that here the value that reads is " 0x69 ".Command execution module C1 will order " at status 0x0B 0x69 " to beam back AT order coding/decoding module C2 (Fig. 3 step S7).
After AT order coding/decoding module C2 receives orders; To its coding; According to above-mentioned agreement, the AT command frame structure of order " at status 0x0B 0x69 " is: " 10,101,010 00,000,000 00,000,000 00,000,000 00,001,011 00,000,001 00,000,000 00,000,000 0,000,000 01101001 ".After AT order coding/decoding module C2 coding is accomplished the AT command frame is sent to communication module C3 (Fig. 3 step S8).
Communication module C3 sends it to connection device B and goes up (Fig. 3 step S9).
Communication module A3 receives the AT command frame from connection device B, and is forwarded to AT order coding/decoding module A2, referring to Fig. 3 step S10.
AT order coding/decoding module A2 receives the AT command frame, and (Fig. 3 step S11) decode to it.Frame structure F1 is " 10101010 "; Be decoded as the return register status command, F2 is " 00,000,000 00,000,000 00,000,000 00001011 ", is register address " 0x0B "; F3 is " 00000001 "; Be with a parameter, F4 is " 00,000,000 00,000,000 00,000,000 01101001 ", and parameter is " 0x69 ".The instruction that parses is " at status 0x0B 0x69 ", sends to UI program module A1 (Fig. 3 step S11).
UI program module A1 receives " at status 0x0B 0x69 " instruction, displays it, and " state value of 0x0B register is 0x69 " is referring to Fig. 3 step S12.
After online read register order having been arranged and having write register command, we can also do online read-write global variable or the like order, like this; The debugging of object module parameter; Just need not revise the code configuration parameter to compiling, having downloaded, save a lot of times, work efficiency improves greatly.
Scalability of the present invention is very strong, increases self-defined AT order and power function, can realize more on-line debugging function.Such as, we are with the flow process of a global variable control program, the different branches of walking when global variable equals different value of program, and we can also find the optimum program circuit that we use, and reach the purpose of debugging.
