Sysctlpwmclockset sysctl_pwmdiv_64
Websysctl is a software utility of some Unix-like operating systems that reads and modifies the attributes of the system kernel such as its version number, maximum limits, and security … WebThe C program code enables and configures the system clock to 40MHz. It sets the PWM frequency based on Equation 5.2. It initializes temporary variables for PWM pulse width adjustment. The GPIO port Dpin PD0 is configured and enabled as PWM output.

Web由于各种arm外围配置的资源各不相同，本人使用是群星的lm3s615,里面含有3路pwm模块，可以产生6路pwm波。spwm与pwm看看，只差了一个，实际上还是有很大的差别的，如果控制电机之类，直接利用pwm波已经足够，但要做个逆变电源，就必须用spwm才行。
