I have a project about sound detect. I am using (ChipKit Max32) as microcontroller and (Bob_09964) as microphones (3 of them to be used)

I want the following things:

1- The software codes of (ChipKit Max32) which uses MPIDE platform.. The codes should insert the 3 analog microphones to the ADC inputs of the micro-controller.. Then the timer will work to detect the fastest signal and set it to zero. Then the second arrived signal with t1 and the third arrived signal to t2.

2- To send the output data to PC using USB port ( what is the code needed?)

3- Process the data in Matlab ( need codes how to extract data through USB port and process it in Matlab) or if possible do the whole processing in the chipkit max32 and display the final output ( character)

The idea is that we have a table of time differences ( already calculated) and we need to gather actual timing gathered from the 3 microphones in order to know which button has been pressed as we are designing an invisible keyboard based on time difference of arrivals. That means if button 1 pressed and the collected data matches one of the calculated table of time differences, it should give final output corresponds to button 1 and so on.

Let me know if you are able to do it.

I have a numerical keypad surrounded by 3 microphones of (BoB-09964) .. I want to connect the three microphones to the microcontroller (ChipKit Max32) and do the ADC inside the PIC.. Then when tapping on any button I should get three sound signals with varying times.. The fastest audio signal is to be recorder by the timer and set time=0 and then start record. The second fastest signal to be recorded and it should equals to t1 and keep recording till the third signal which equals to t2.. Then per each tap I want to transfer the data ( t1 and t2) from the microcontroller to the PC through USB . At PC, Matlab will be used to analyze the data in order to convert the gathering t1 and t2 to the corresponding button pressed.

So I need all the codes in PIC and Matlab to get the final output.
