25 25
26 26 The pwm api gives you a standard way to drive any pwm pin on any processor.
27 27 With this api you will be able to open and configure your PWM module, define the
28 28 associated pins when applicable and set the duty cycle and frequency. Note that depending
29 29 on the target architecture you can have soft or hard PWM.
30 30
31 31 A simple example to configure and use PWM4_CH4 on STM32 discovery for example.
32 32 \code
33 33 // lets open PWM4_CH4
34 34 //config :
35 35 // -TIMER = TIMER4 (PWM4=TIMER4)
36 36 // -PWM channel = 4
37 37 // -PWM output = PD15
38 38 // -PWM frequency = 1kHz
39 39 // -PWM duty cycle = 40.5%
40 40 pwmopen(PWM4_CH4,PD15);
41 41 int error = pwmsetconfig(PWM4_CH4,1000,40.5);
42 42 //check that everything is ok
43 43 if(error!=-1) //=> no error
44 44 {
45 45 //to change duty cycle to 15% for example:
46 46 pwmsetdutycycle(PWM4_CH4,15.0);
47 47 //you can also change the frequency:
48 48 pwmsetfrequency(PWM4_CH4,455000);
