I'm using a Nanode 5 with WiNode backpack and for the past year on and off have been developing an increasingly complex sketch which uses several PWM outputs driving LEDs through transistor amps. Because of its complexity I have been writing test programs for each section - inputs, outputs, RF, etc - to test hardware as much as functionality. Combined together the complete sketch compiles, uploads and works fine apart from the LED attached to Digital Output 11 which comes on and stays fully lit continuously, rather than being controlled by the sketch.
It seems that the RF backpack/shield has over-ridden pin 11 for some reason. Bending the Pin at Digital 11 linking the 2 boards out of the way just makes the RF tx LED come on continuously.
I am using pins 3 & 5 for other PWM outputs. Pin 6 is the onboard LED which is a bit of a waste of a PWM output, and pins 9 & 10 are unavailable as copper tabs have become detached during the ongoing development.
Is there a software fix that will get me back control of Pin 11?
Can I reconfigure another digital out, say pin 4 as a PWM?
