使用51单片机的输入口P3作为驱动口，步进电机使用的是4相电机28BYG-48，使用ULN2003作为驱动芯片，P3.0控制A相，P3.1控制B相，P3.2控制C相，P3.3控制D相，通过循环遍历数值表，使P3.0-P3.3交替产生高脉冲，频率不宜过高，太高的话步进电机只会内部振动，并不转动。相邻高电平之间的时间间隔在1-10ms之间就可以了

经过定点优化的G723、G729的codec In case you do not want to install IPP, then you"ll get twice better performance out of ITU-T code if you build it with GCC 4.5 or Intel CC with LTO/IPO enabled. Still, even with ICC, it is 10x slower than IPP - 30ms vs 3ms of processor time to encode one second of G.729 audio on modern hardware. G.723 is around 100ms. GCC with LTO is 2x slower than ICC. For ITU-T code, a Core2 class processor is recommended.
