wavefrom comparing

Hi,

 my application is to check the PCB i/o pins... first i have to corresponding signal to every pin in GOOD PCB board and the output of each pin should saved in excel with the help of write to spreadsheet.. then the database be act as master for other PCB boards..

 

If i wanna check the other pcb board means the same corresponding signals should be send to the each pin of the PCB board.. the Output received from the board should check with the data already saved in the database if it is match's means Status LED should Glow otherwise its not to glow...

 

pls help me to finish this application.. i have attach model vi with post and excel too....

Regards,

See i have to send a signal (simulate signal) to the PCB board (GOOD PCB BOARD FIRST)  to get the output signal from the board.. and its should save in the excel sheet.... (For example first the customer will give good Pcb board to me) i have to note all the signal received from the board wrt input signal.. its cos further they'll priovide the faulty PCB BOARD to check  the board whether its having error in it...

 

In the last Post i have attached only the method of my Program...

my doubt is if all the received signal are saved in the excel sheet first.. then  when im going to checking faulty Pcb board with its received signal i have to compare this received signal with data save in the database(pin 0 - sine signal input and output is may be sine wave)...

(ex: PCB board will have 40 pin each pin will have diff signal and corresponding output should to be verify..)

Actually in my program i have two part that is 1. Learning and 2. Comparing

 

LEARNING:smileysad:GOOD PCB  BOARD WITH 25 PINS) 

 A. I have to send the signal each and every pin in the board 

 b. secondly i have received the o/p signal from board and save in excel sheet it'll act as like MAIN DATABASE...

 c. Suppose for the pin 0 input signal is sine wave means o/p signal from that pin may be sine wave(just consisder0

 d. This MAIN DATABASE should not to disturb after received o/p from the Board.

NOW I HAVE ATTACHED THE  PROGRAM WITH ONLY ONE SIGNAL i.e., SINE WAVE...

 

COMPARING:smileysad:FAULTY PCB BOARD)

 

a.  Same steps should be follows here

b. but instead saving the o/p received signal in a database we have to compare the received signal with

   the MAIN DATABASE SIGNAL...

c. if both data match the status should be in HIGH otherwise it should be in low condition

    HIGH ---- means its matched

    LOW ----- means its not matched....

my problem is that  i have the sine wave signal data in the excel (DATABASE) and then i should call the data base and should  compare with the received signal...i HAve same sinewave for input and comparing the another sine wave(i.e., SIMULATE SINE SIGNAL) the status giving its not match???

can u send any program related to comparing like my program(i.e reading from text file with multi signal data and comparing with real time signal )... pls if u send it to me means it'll help me more... im new for this dicussion form i dont know to establish my question clearly.. dont mistake me..

 

 

Anybody help me to complete my program and my problem  too...:smileysad:
