analogWriteMaxFrequency() (PWM)

Since 0.6.0:

Returns maximum frequency that can be used with analogWrite() on this pin.

analogWriteMaxFrequency() takes one argument:

• pin: the number of the pin

// EXAMPLE USAGE
pinMode(D1, OUTPUT);     // sets the pin as output
analogWriteResolution(D1, 12); // sets analogWrite resolution to 12 bits
int maxFreq = analogWriteMaxFrequency(D1);
analogWrite(D1, 3000, maxFreq / 2); // 3000/4095 = ~73% duty cycle
