本例载波频率为20KHz,或载波周期为50μs。DSP晶振10MHz,内部4倍频,时钟频率为40MHz,计数周期为25ns。假设调制波频率由外部输入(1~50Hz),并转换成合适的格式(本例为Q4格式)。调制系数M为0~0.9。死区时间1.6μs。最小删除脉宽3μs。
主程序的工作是根据输入的调制波频率计算N、2N和M值。
-Example for the carrier frequency 20KHz, or carrier period is 50μs. DSP crystal 10MHz, internal 4 multiplier, the clock frequency of 40MHz, counting cycle 25ns. Assuming wave frequency modulation by external input (1 ~ 50Hz), and converted into an appropriate format (in this case for Q4 format). Modulation coefficient M is 0 ~ 0.9. Dead time 1.6μs. Delete the smallest pulse width 3μs. The work of the main program is based on input frequency modulation wave calculation of N, 2N and M values.

ST套件产生汽车防盗器报警声,本实例的目的是让大家学会用单片机产生声音的方法,学会计算程序所用时间 本实例的功能是能用16F84产生汽车防盗器的报警声,频率分两个0.1s第一个
0.1S频率从1.8K-3.5K匀速增加第二个0.1S频率从3.5K-1.8K匀速减少,
程序复位后,按S2喇叭叫两声,按S3喇叭叫15秒,中途可按S5停止.
PIC单片机
烧写时应注意:配置位已经在程序中写明,加载HEX文件时会自动加载,烧写时不用再手动设置配置位。
实验时请注意套件跳线选择;-pic
