Description: 详细介绍目前制作PCB的方法及制作过程。
1、用protel 画出您所需要的印刷电路板图。
2、将上图打印到热转印纸(注意不要打印顶层丝印图)。
3、将热转印纸上的碳粉通过热转印机转印到敷铜板上 。
等等。

Description: 1.VR1 为 3X3 体积硬封 10K 可调电位器，可以进行对比度调节。当电位器缺口
大致对准 R1 电阻时，此时液晶屏对比度为正常范围内，显示较清晰，可以液晶
接口第三脚 V0 不用接。
当电位器缺口对准 VR1 丝印时，此时相当于电位器是零电阻值，可以用螺丝刀
手动调节液晶电位器至 R1 位置直到显示屏正常清晰显示
液晶屏自己带电位器时，第三脚 V0 可接可不接，不接必须调节液晶背面电位器
至 R1 位置。接了 V0 可以通过外接电位器调节，同时也可以用液晶电位器调。
2．液晶接口 18 脚 VOUT 可以不接 悬空
3.串并行显示可通过下列两种方式调节：
一种 PSB 脚控制 程序内部高低电平选择 H-并行；L-串行
二种 JP2 短路点有 3 点，S 和中间点连起来为串行 P 点和中间点连起来为并行
如取字模出现乱码时，请一定把 JP2 短接 P 为并口 S 为串口
4：此液晶屏只支持一种电压，发货为 5V 只支持 5V ，3.3V 只支持 3.3V-1.VR1 hard seal 10K for 3X3 volume adjustable potentiometer, the contrast can be adjusted. When the potentiometer gap
When roughly aligned R1 resistance, and the LCD display contrast within the normal range, showing more clearly, can the LCD
The third leg V0 interface not connected.
When VR1 potentiometer alignment notch silk, then the equivalent potentiometer resistance value is zero, you can use a screwdriver
Potentiometer to manually adjust the LCD display normal R1 position until a clear display
When the LCD screen yourself potentiometer, the third leg V0 can be accessed from time to connect, then do not have to adjust the LCD back potentiometer
To R1 position. V0 can pick up an external potentiometer adjustment, but you can also use the LCD potentiometer adjustment.
2. LCD Interface 18-pin VOUT can not take vacant
3 serial parallel display can be adjusted by the following two ways:

Description: 实现功能：
控制2个气缸，没有任何传感器。第1个气缸先伸出去，1秒钟后再收回来。然后第2个气缸再伸出去，1秒钟后再收回来，算完成一个过程，然后重头开始循环下去。每一个过程要计数加1显示在右边的4位数码管上，左边的4位数码管显示设定的最大计数上限，一旦超过这个计数上限就自动停止。有4个按键，一个按键用来启动，一个按键用来急停。另外两个按键是加减按键，用来设置左边显示的最大计数上限。断电要求数据不丢失。如果同时按下加减两个按键，可以清零当前计数的内容。这4个按键都是独立按键。S1键是加键，S2键是减键，S3键是启动键，S4键是急停键。其中74HC595驱动丝印为D1的LED灯模拟第1个气缸，丝印为D2的LED灯模拟第2个气缸。-To realize the function of:
2 cylinder, no sensor control. The first cylinder first out, back in 1 seconds after the harvest. Then the second cylinder and then back out, 1 seconds after the close, complete a process, and then start the cycle continues. Each process to count 1 shows in 4 digital tube on the right side, 4 digital tube display on the left side of the maximum count limit, once exceed this limit will automatically stop counting. There are 4 buttons, a button to start, a key to stop. In addition two buttons and button is used to set the upper limit, the maximum count shown on the left. The power requirements of the data is not lost. If you subtract two keys pressed at the same time, the count of the content can be cleared. The 4 key is independently pressed key. The S1 key is key, the S2 key is down button, S3 button is the start button, the S4 button is the emergency stop button.
