HeliRCrx analog output pin assignment for WiFi Bee

[TriCopter]

The WiFi Bee only brings out analog pins 6 and 7 not 3 which is the default pin for HeliRCRx. Where can I reassign the default pin to A6.  Also the RCKit 2.3 "testsuite" no longer initializes the WiFi bee. Just a quick question ... Would it be better to current limit the Ir LEDs with a resistor rather than connecting them directly to the +5 supply?  Also wouldn't it be better to put the LEDs in parallel so they would all draw the same current and be the same brightness. When viewing the Ir with a digital camera I noticed the series LEDs have a different brightness due to the junction resistance (small voltage drop) of each LED.

 

Thanks

The IRrc module uses timer2 pin to modulate the IR signal. Timer2 can only be
used with pin 3 (or pin 9 on a mega).

You can *not* set the timer output to an arbitrary arduino pin.

I have not tested with that device.
Are you sure you are using the latest versions of RCKit and IRRc, and that
your sketch is calling setTransceiver as per the example HeliRCRx in the
latest version?

Perhaps. I leave the electronics design to you.

Cheers.

My misunderstanding ... digital pin3 is available ... Thanks ... putting LEDs in parallel worked much better for my application.
