一个不怕掉电的超级万年历源程序及文件，非常有意思，大家还可以提出修改意见！-A super-power-down calendar is not afraid of the source code and documentation, very interesting, everyone can make changes!

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.

基于DS18B20温度传感器的设计程序 要求为：第一，由DS18B20获得外部温度信息然后通过数码管显示，显示值为三位，两位整数，一位小数。第二，判断温度是否大于 50℃，若温度在50℃以上，显示红色发光二极管发光；若温度在50℃以下，显示绿色发光二极管发光。-DS18B20 temperature sensor based on the design of procedural requirements: first, by DS18B20 access to external temperature information through a digital display, showing a value of 3, two integer, a decimal. Second, to determine whether the temperature is greater than 50 ℃, if the temperature at 50 ℃, which indicates that the red light-emitting light-emitting diodes if the temperature below 50 ℃, showing a green light-emitting diode LED.
