脉宽调制(PWM)是一种常用的技术,用以实现模拟电路的数字化控制。PWM使用一个方波脉冲,其脉冲宽度调制后导致波形均值的变化。在此PWM实现中,经过MOSFET电路的电流控制了输出到负载风扇的功耗。 本参考设计使用一个PLD和一个MOSFET电路实现了PWM风扇控制,提供了一个简单的2引脚风扇的速度控...

You can easily modify the driver parameters through specific functions able to change the bridge configuration, the number of motors or the PWM frequency. You can also use callback functions with: • the flag interrupt handler, when an o...
Load of interrupt - The portion of the time that the microcontroller spends doing soft PWM. A value of 1 would indicate that 100% of the time is spent in the PalatisSoftPWM ISR, meaning that no clock cycles are left to execute any other code. Clock cycles per interrupt - The number ...
