Serial Communication With My Arduino

[happysmile]

please help !

Using ARDUINO UNO to generate serial Comm signal "1111111111111111 \ 13 \ 10" which is a array in my Arduino application.

This array is status ON / OFF of 16 relays. ON = logic 0 and OFF = logic 1.

mydevice = Serial Ascii / 9600 N81

canal_0 in to see the data "1111111111111111" is going well, except for the first location. When it is "0" disappears.

Q. how to get state 1 to 16 in separate channels, canal_1 to canal_16

I'm not sure how you are getting the data now, so I'll just explain how to do it all. I'm going to assume you have mydevice setup with a NULL protocol. I'm also going to assume that your device sends the data on its own. In a sequence put:

device.mydevice.purge()
private string datain
private data
while(1)
   try
      datain = device.mydevice.readuntil(10)
      if (getlength(datain) != 17) // 16 channels plus the carriage return
         continue
      endif
      data = asca(datain)
      for (private i = 0, i < 16, i++)
         execute("canal_" + doubleToStr(i+1) + ".addValue(" + doubleToStr(data[i] - 48) + ")")
      endfor
   catch()
      ? strLastError
   endcatch
   delay(0.05)
endwhile

That should do it, though of course I didn't test it. I used an ascii trick. ASCA() converts the string into an array of numbers. In your case, its either 48 for "0" or 49 for "1". But I want 0 or 1 in the channel, so I subtract 48.

Hello Guru.

 

did you create a channel like "test type"?

 

I can´t show the values.

I have trying to use the same code, but for read 16 ascii value. 

 

thanks.

Yes, you would create 16 channels canal_0 through canal_15, all Device Type "Test", I/O type "A to D", Timing = 0.
