ARM延时问题一直是比较令人头疼的问题，因为ARM是流水工作，并且在程序跳转的时候不遵循流水规律，所以不像51单片机一样好计算，今天为了调18B20，因此把ARM的延时问题研究了一下。总结起来，有三种计算方法。
1.做好看一下编译出来的汇编语句，再自己用笔做个加减乗除，算出结果。
这种方法最直接，但是最麻烦，因为汇编指令的时间不好计算，并且要弄明白流水的工作原理，一个指令执行的时间等，...[Details]

O Introduction
传统的逆变器虽然技术成熟可靠、应用广泛,但存在体积大且笨重、音频噪音大、系统动态特性差等缺点.用高频变压器替代传统逆变器中的工频变压器,克服了传统逆变器的缺点,显著提高了逆变器的特性。
单向电压源高频环节逆变器 具有单向功率流、三级功率变换(DC/HFAC/DC/LFAC).变换效率和可靠性不够理想、但应用较广泛等特点;高频脉冲直流环...[Details]
