关于电路设计的几点经验，从原理设计到实际应用，对一些个问题、经验综述

这是点阵程序 个人认为先学点阵再学lcd比较好 p0 p2分别接16*16点阵的高八位和低八位(纵向取模) p3口低四位接4-16线译码器（74ls154）译码器低电平为列选 消除鬼影的方法：-This is the program individual lattice lattice before you think lcd is better to learn p0 p2, respectively, then 16* 16 lattice of high and low 8 8 (vertical modulus) p3 I received a low four 4-16 Line Decoder browser (74ls154) low-level decoder for the elimination of ghosting out the election approaches:

尽量朝“单片”方向设计硬件系统。系统器件越多，器件之间相互干扰也越强，功耗也增大，也不可避免地降低了系统的稳定性。随着单片机片内集成的功能越来越强，真正的片上系统SoC已经可以实现，如ST公司新近推出的μPSD32××系列产品在一块芯片上集成了80C32核、大容量FLASH存储器、SRAM、A/D、I/O、两个串口、看门狗、上电复位电路等等。 -North Korea as the "single-chip" design direction of the hardware system. System devices more mutual interference between devices are more strong, power consumption is increased, it will inevitably reduce system stability. With MCU with on-chip integration of more powerful, the real system-on-chip SoC can achieve, such as ST"s new PSD32 x x in a series chip integrates exertion nuclear, large-capacity flash memory, SRAM, A/D, I/O, 2 serial port, watchdog, the power-on reset circuit and so on.

从虚拟终端输入8个任意数据，通过串口传送给单片机的led_buf缓冲区，并在8个led上显示；按回车键对led_buf缓冲区中的数据进行由小到大排序，排序结果在led上显示。-From the virtual terminal eight arbitrary input data, through the serial port send buffer led_buf MCU and 8 led display led_buf press Enter to buffer the data from small to big sort, to sort the results in the led display.
