void pwmWrite(uint8_t pin, uint16_t val, uint8_t outputMode)
The pwmWrite() method sets the value of a PWM output pin.
Black Box Input
The pin number, desired value to be written and the output mode are provided .
Black Box Output
None. Single signature only.
By default possible values range from 0-255 (see the setPWMResolution() command). On Wiring v1 boards the PWM capable pins are: 29, 30, 31, 35, 36 and 37. On Wiring S board the PWM capable pins are: 4, 5, 6, 7, 19 and 20. Note: analogWrite is an alias for the pwmWrite() command. Doing pwmWrite() on a non PWM pin will cause the pin to be set to HIGH with no other effect.
For Wiring 1.1
According to Issue 9, pwmWrite() will be defined as:
void pwmWrite(pin_t pin, uint16_t val, uint8_t outputMode)
See Issue 9 for more details.
