◆ pwm2ch_set()
| void pwm2ch_set |
( |
pwm2ch * |
device, |
|
|
int |
pin, |
|
|
int |
channel, |
|
|
int |

|
) |
| |
Set a PWM signal's high time.
- Parameters
-
| *device | The pwm2ch pointer/process ID returned by pwm2ch_start. |
| pin | The pin to send the PWM signal. |
| channel | 0 or 1. |
| dacVal | For PWM, use 0 to cycleMicroseconds. To shut down a channel and set the I/O pin to input, use -1. |
◆ pwm2ch_start()
| pwm2ch* pwm2ch_start |
( |
unsigned int |
cycleMicroseconds | ) |
|
Start PWM process in another cog.
- Parameters
-
| cycleMicroseconds | The number of microseconds each cycle lasts. |
- Returns
- *device A pointer that should be stored in a pwm2ch *variable and used as a process ID in other pwm2ch_... function calls.
◆ pwm2ch_stop()
| void pwm2ch_stop |
( |
pwm2ch * |
device | ) |
|
Shut down pwm2ch process and reclaim cog and I/O pins for other uses.
- Parameters
-
| *device | The pwm2ch pointer/process ID returned by pwm2ch_start. |
