Problem with using analogWrite and digitalWrite. Oct 19, 2017 10:16:08 GMT

Hi.

I have a problem using analogWrite and digitalWrite in the same sw.

I see that both D2 and A2 is defined as 2.

One digital pin is declared as:

const int sh_reg_serin = 2;//D2 to pin 14 of shift register serial in

And another analog pin is declared as:

const int LedPin[12] = {26, 25, 24, 23, 22, 5, A0, A1, A2, A3, DAC0, DAC1};//Led pins free for indication.

When I remove code for LED ctrl, the shiftregister works fine.

This is my LED ctrl line:

analogWrite(LedPin[sw], (255 * RFSwitch[sw]));

RFSwitch[sw] is 1 or 0.

Is there something I have missed?

Best Regards

However will change this in a future hardware revision!
