Run a high speed pulse width modulation (PWM) class that can output up to two channels of duty cycled PWM at a single frequency.
The two channels are channel X and channel Y.
Requires a cog to operate. No external hardware is required beyond whatever you are PWM'ing.
You can use this class to PWM H bridges, LEDs, audio, etc.
- Todo:
- (SRLM): figure out the maximum frequency (as a function of clock speed)

void PWM2::SetDutyX |
( |
const int |
percent) | |
|
|
inline |
Output a square wave with specified duty cycle.
- Parameters
-
percent | The duty [0..100] to PWM. 0 is off, 100 is full on. |
void PWM2::SetDutyY |
( |
const int |
percent) | |
|
|
inline |
Output a square wave with specified duty cycle.
You can change this during operation.
- Parameters
-
percent | The duty [0..100] to PWM. 0 is off, 100 is full on. |
void PWM2::SetFrequency |
( |
const int |
frequency) | |
|
|
inline |
Set the frequency to output channel X and Y on.
- Todo:
- (SRLM): SetFrequency doesn't seem to actually change the frequency (at least once the cog is started...)
- Parameters
-
frequency | The frequency in Hz, [0..40000??] |
void PWM2::SetPinX |
( |
const int |
pinX) | |
|
|
inline |
Set a pin to PWM out on.
You can change this during operation.
- Parameters
-
pinX | The I/O pin [0..31] to set the X channel on. |
void PWM2::SetPinY |
( |
const int |
pinY) | |
|
|
inline |
Set a pin to PWM out on.
You can change this during operation.
- Parameters
-
pinY | The I/O pin [0..31] to set the Y channel on. |
void PWM2::Start |
( |
void |
) | |
|
|
inline |
Start a PWM driver in a new cog.
Stop the PWM driver (if running)
