The example aims to dim a LED and and output, however the output (PIO0_6) doesn't dim. I thought it was a pullup issue, but it isn't. I was trying for hours in my own code, before to double check the example, to make the output get the PWM to work (10KHz, 50%) and I didn't succed. After trying the on-board PWM example the only thing I saw on my oscilloscope was an eternal 'hi' level at the PIO0_6 pin. Let me repeat that the output at PIO0_7 (red LED) works nicely. Something is missing on the example, any ideas?
