程序运行于C8051F020,主要功能是利用C8051F020自带的DAC生成一个正弦波-procedures in the C8051F020, Its main function is to bring their own use C8051F020 the DAC generating a sinusoidal

该教程是基于SPCE061A凌阳16位单片机的教学，由浅到深，非常适合初学者-it is the lession of SPEC061A ,and it is good for the freshman

包含51模拟IIC和硬件IIC的操作代码-IIC contains the 51 simulation and hardware IIC operation code

51系列单片机的IIC软件包，模拟通信软件包，可以和具有IIC的芯片使用-51 Series MCU IIC package, analog communications package, you can chip and the use of IIC

单片机系统上电后，P0 口和 P1 口都被清 0。然后，你规定一个由 6 个数字构成的序列（每个数字从 0～F 中选取），比如 E、8、9、0、7、F。然后每次当单片机检测到外部中断 0发起中断时间时，读取 P0 口和 P1 口上的状态值，当连续 6 次外部中断事件的对应的数字序列构成你所设定的序列后（举例来说，如果 P0.0 是 1，P0 和 P1 的其他管脚是 0，那么我们称为检测到一次数字 0），从串口打印输出一幅类似下图的 16×16 的ASCII码的圣诞树图片。-Single-chip microcomputer system after power, P0 and P1 mouth I have been ching 0. Then you set a six figure constituted by the sequence (each number from 0 ~ F in selected), for example, E, 8,9,0,7, F. And then each time a single-chip detects external interrupt 0 initiated interruption time, I read the P0 and P1 mouth on the state value, when a row 6 times the corresponding external interrupt events constitute digital sequence set your sequence (for example example, if P0.0 is 1, P0 and P1 of the other pin is 0, then we called a number of detected 0), a printout from the serial port under similar 16 × 16 map of the ASCII code of the Christmas tree图片.

这是mcs-51和EEPROM AT24C512 I2C总线接口器件接口的例子 -This is a mcs-51 and EEPROM AT24C512 I2C bus interface device interface example
