ios - generating the square wave with pulses -

-

I am trying to modify the method of creating square wave

Can generate different pulse width with 0.3ms each delay in one per period I have seen that sampleBuffer is responsible for generating pulse signals, but I'm not sure how to do the pulse function for such a specific pattern Can you please make me tell that pulse What is the Library function on AudioTrack.h?

Below is my code 

  zero generated square (SInt16 * sampleBuffer, int numframes, float sample rate, float frequency, float amp) {if (amp & gt; ; 1) amp = 1; If (amp & lt; 0) amp = 0; Amp = amp * SHRT_MAX; Float samplesPerCycle = sampleRate / frequency; For (Int i = 0; I  0.5) {Sample Buffer [I] = amp; } And {sample buffer [i] = -1 * amp; } SquareIndex = squareIndex + 1; If (squareindx> = cycler at the sample) squareindex- = samayperecyclical; }}    
 
 
 Here's my solution for the same problem 
 My issues I make pulse with 1 mms width, which I am modifying with the fill value till +/- 0.5ms. According to the filling, I create a square wave with a width of 0.5-1.5 MB.  
  int squareIndex = 0; Zero-Generated Squeeze (SInt16 * Sampler buffer, intro neframe, float sample rate, float flawl, float amp) {// fill in the value = pulse width value in // // fillValue = [-20, 20]; If (amp & gt; 1) amp = 1; If (amp & lt; 0) amp = 0; If (fill value & gt; 20) fillValue = 20; If (Fill well and lieutenant; -20) fill value = -20; Amp = amp * SHRT_MAX; Float samplesPerCycle = sampleRate / 50; // sample / cycle = 882 // 1ms = 41 frames - & gt; 0.5 ms = 20 (.5) frame // 0.3 ms = 12 (.3) frame # Purgama mark in your case - PWM for (int i = 0; i & lt; nffms; i ++) {// if ( FMODF (Square Indexes, SamplePearcycle) / SamplesCycle and LT; 0.05) {If (SquareIndex <41 + Fill Value) {sampleBuffer [i] = 1 * SHRT_MAX; } And {sample buffer [i] = 0; } SquareIndex = squareIndex + 1; If (squareindx> = cycler at the sample) squareindex- = samayperecyclical; }}

Pass DB Connection parameters to a Kettle a.k.a PDI table Input step dynamically from Excel -

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu

I know that it can speak as a very famous topic, but something that helps me with it Not found This scenario is: I have my functions function, no matter what's inside, it's a generic function that may depend on other toolboxes.
