MC9S12XEP100 PLL时钟配置例程(MC9S12XEP100 PLL setup)

说明：  结合曲线拟合，进行温度的曲线判断，里面加入了最小二乘法，最要应用于STM32ZET6芯片(Fitting temperature curve)

亮度可调节LED灯，采用双色LED灯， LED调节亮度是通过调整通过它的PWM驱动电流大小得到的,节能灯一般是不能调整亮度的。本设计在项目中应用，绝对可以用。(Brightness can be adjusted LED lamp, using dual color LED lamp, LED adjust brightness by adjusting its PWM drive current size, energy saving lamps can not adjust brightness generally. This design is applied in the project, and it can be used absolutely.)
