- Thanks, Nagi

Here's the circuit I'm using


note that for parts, I'm actually using 220r for 470r. And, for 0.01uf, I'm using 103 cap.

The "w" is hooked up to Pin 5 on my demo board.

Here's the code I'm using:
Note that the Sensor and React behaviors are running on 2 separate COGs in a repeat block

[b]'// Sense IR[/b]
[b]if (Flag_EnableIR == 1) 
[/b]  '// Get IR value via RCTime 
  DIRA[noparse][[/noparse]Pin_IR] := 1 
  wait(230) 
  OutA[noparse][[/noparse]Pin_IR] := 1 
  wait(0) 
  DIRA[noparse][[/noparse]Pin_IR] := 0 
  wait(230) 
  [b]SensoryData[noparse][[/noparse]Data_IRIndex][/b] := [b]BS2.RCTime(Pin_IR,1) [/b]

··

[b]'// Display IR result[/b][b]if (Flag_EnableIR == 1) 
[/b]  LCDDisplay(11,1, string("I:")) 
  LCDDisplay(13,1, (num.decf([b]SensoryData[noparse][[/noparse]Data_IRIndex][/b],2)))

Reposting due to no response

not sure why - Either 1) I must be completely dumb or stupid (which is quite possible) w/ this question [noparse]:)[/noparse]
2) Nobody else has a need to work w/ or interest in this device [noparse]:)[/noparse]

I will try this one more time - If I don't hear back, that is fine. I will drop it and look for other avenues to find answers to this question and post it here.

thanks in advance guys!

Alibe,

I'm sure noone is actually using the device. That is what I found to be true with the MAX 1202.

You are lucky....you will be a pioneer.
