/**
|
||||
* FAST PWM FAN Settings
|
||||
*
|
||||
* Use to change the FAST FAN PWM frequency (if enabled in Configuration.h)
|
||||
* Combinations of PWM Modes, prescale values and TOP resolutions are used internally to produce a
|
||||
* frequency as close as possible to the desired frequency.
|
||||
*
|
||||
* FAST_PWM_FAN_FREQUENCY [undefined by default]
|
||||
* Set this to your desired frequency.
|
||||
* If left undefined this defaults to F = F_CPU/(2*255*1)
|
||||
* ie F = 31.4 Khz on 16 MHz microcontrollers or F = 39.2 KHz on 20 MHz microcontrollers
|
||||
* These defaults are the same as with the old FAST_PWM_FAN implementation - no migration is required
|
||||
* NOTE: Setting very low frequencies (< 10 Hz) may result in unexpected timer behaviour.
|
||||
*
|
||||
* USE_OCR2A_AS_TOP [undefined by default]
|
||||
* Boards that use TIMER2 for PWM have limitations resulting in only a few possible frequencies on TIMER2:
|
||||
* 16MHz MCUs: [62.5KHz, 31.4KHz (default), 7.8KHz, 3.92KHz, 1.95KHz, 977Hz, 488Hz, 244Hz, 60Hz, 122Hz, 30Hz]
|
||||
* 20MHz MCUs: [78.1KHz, 39.2KHz (default), 9.77KHz, 4.9KHz, 2.44KHz, 1.22KHz, 610Hz, 305Hz, 153Hz, 76Hz, 38Hz]
|
||||
* A greater range can be achieved by enabling USE_OCR2A_AS_TOP. But note that this option blocks the use of
|
||||
* PWM on pin OC2A. Only use this option if you don't need PWM on 0C2A. (Check your schematic.)
|
||||
* USE_OCR2A_AS_TOP sacrifices duty cycle control resolution to achieve this broader range of frequencies.
