是介绍使用单片机控制led显示的程序,可以显示多种样式.-Is to introduce the use of single-chip control procedures led display, can display a variety of styles.

由于输出的是方波，比较难听:-) 只能说是非常难听:-)为什么呢？只因为输出的是方波,包含了大量的奇次谐波。 你可以用双龙的"虚拟仪器"分别产生正弦波、三角波和方波听一下，正弦波感 觉就比较纯正，而方波则要多难听有多难听！-As the output is a square wave, more bluntly :-) can only say that it is very nasty :-) Why? Simply because the output is square wave, including a large number of odd harmonics. You can use Shuanglong

我用单片机8952和电压比较器339做了一个简单的电容容量测量表，参数大 致如下： 电容测量范围为1pF-9999.99uF，最小分辨力为1pF。分为5个量程，可以自 动切换量程，也可手动切换。 另外，有简单的频率计功能，能测量0-60MHz的数字信号频率（TTL电平）； 还可以产生几个单点频率的方波信号（比如1KHz）。 采用1602LCD作为显示器；4个按键控制；使用24C01保存当前设置值，不用 每次开机重新设置。可单5V供电，也可9V交流供电 -I used the single-chip 8952 and the voltage comparator 339 to do a simple capacitance measurement table, parameters are as follows: capacitance measurement range 1pF-9999.99uF, the minimum resolution for the 1pF. Divided into five ranges, you can automatically switch range can also be manually switched. In addition, a simple frequency meter function, capable of measuring 0-60MHz frequency digital signal (TTL level) can also lead to several single-point-frequency square-wave signal (for example, 1KHz). 1602LCD used as a monitor 4 button control use 24C01 to preserve the current settings, do not reset each boot. Can be a single 5V power supply, 9V AC power supply can also be

缺水传感器V1.0，绝对原创，传感器好-Water sensor V1.0, an absolute original, a good sensor

此程序为利用mage8 AVR 和EM4094实现读取TYPE B类型卡的C程序、读卡稳定、这个项目我们做了好久、非常不错的程序、很适合做这方面产品的朋友们参考-This procedure for the use of mage8 AVR and the EM4094 Read TYPE B to achieve the type of card C procedures, reader stability, the project we have done for a long time, very good program, it is suitable for products in this area refer to my friends

完整可以对24C04,24C16A进行正常读写功能的C51代码.-Integrity can 24C04, 24C16A normal read and write function code C51.
