Description: 一些应用中，经常要用到双串口，但是一般单片机只提供一个串口，其实完全可以用普通I/O口模拟一个串口。以下的程序是我编写的模拟串口程序，程序中使用了单片机的定时器0，和INT0中断。数据的发送和接收由中断程序自动进行。程序已经过AVR仿真器仿真和实际烧片使用，证明可靠。有一点需要说明的是，此模拟的串口为半双工方式。
主程序中，单片机将标准串口设置为115200bps,将模拟串口设置为19200bps。单片机将标准串口收到的数据从模拟串口发送出去，将模拟串口接收到的数据从标准串口发送回来。-some applications, the regular use of the dual serial port, but most only provide a microcontroller serial, In fact, the general can use I / O simulation of a serial mouth. Following the procedure is that I serial simulation procedure is the use of the computer's timer 0, and INT0 interruption. Data sending and receiving process by automatically suspended. Procedures have been AVR Simulator simulation and actual use of burn unit proved reliable. It should be explained that this simulation of half-duplex serial port. Main program, SCM standard serial port set to 115,200 bps. Serial analog set to 19,200 bps. SCM standard serial data received from analog to serial sent, Serial analog to receive data from the standard serial sent back.

Description: AVR单片机定时器2的异步操作功能用作实时时钟的效果。同时讲解了BASCOM-AVR中关于时钟硬件配置方面的语句。在BASCOM的概念里主要分为SOFT和USER两大类时钟产生的方法。利用芯片定时器的异步功能称为软时钟，利用专用时钟芯片则要用户自己编写相应的处理程序，所以称USER。但不管采用哪种方式，相关的中断服务程序或是函数都要支持DATE$和TIME$以及_sec , _min , _hour, _day , _month , _year等系统内部变量。程序的其他部分可以直接存取这些变量，使得时间操作变得规范化，大大方便了程序设计-AVR microcontroller Timer 2 functions as a real-time clock asynchronous operation results. Also explained the BASCOM-AVR clock hardware configuration on the statement. Concept of years in BASCOM divided into two categories USER SOFT and clock generation method. Use of chip asynchronous timer feature called soft clock, using dedicated clock chip will have to write the corresponding user' s own procedures, so that USER. But Either way, the relevant interrupt service routine, or function must support DATE $ and TIME $ and _sec, _min, _hour, _day, _month, _year other variables within the system. Other parts of the program can directly access these variables, making time operation has become standardized, greatly facilitates programming

Description: Atmega 16单片机，这里利用T/C1定时器中断来产生PWM波形。在ICC AVR编译环境下，利用tool 菜单中的application builder生成一个简单的PWM波程序。这段程序以PA0作为PWM波的输出端口。利用T/C1定时器比较匹配和溢出产生两次中断来改变PA0的输出电平。具体过程为：计数器TCNT1从初始值开始不断计数，当发生比较匹配时，把PA0置为低电平，计数器继续计数，当发生溢出中断时，计数器回到初始设定值，并把PA0置为高电平。从而在PA0端口获得一稳定持续的PWM波形，在主程序中改变比较值，即可改变波形占空比，而频率不变。-Atmega 16 microcontroller, T/C1 timer interrupt to generate a PWM waveform. ICC AVR compiler environment, the application builder tool menu to generate a simple PWM wave program. This program PA0 as PWM wave output ports. The use of T/C1 timer compare match and overflow twice interrupted PA0 to change the output level. Process: the counter TCNT1 from the initial value began to count, compare match occurs, the PA0 set low, the counter continues to count when an overflow interrupt occurs, the counter back to the initial setting, and PA0 is set to the high level. PA0 port access to a stable and sustainable PWM waveform, change the comparison value in the main program, you can change the waveform duty cycle, and the frequency is the same.
