注:protel电路图 1.INPUT12为高压气压和低压压传感器输入端. 2.OUTPUT为充气输出控制端. 3.当高低压有接地信号时,电机正转,气阀打开. 4.INPUT2低气压时有信号时,充气OUTPUT输出,充气电机转. 5.RS1与RS2是调节阀门距离用地 6.RS3是与气阀电机同步时,是气阀电机的转动圈数传感器. 7.RS4是调节延时时间用地-Note: protel circuit 1.INPUT12 and low-voltage high-pressure pneumatic pressure sensor input. 2.OUTPUT output control for the inflated side. 3. When the high and low pressure have a grounding signal when the motor is transferred, the valve opens. 4.INPUT2 low pressure when there is signal output OUTPUT inflatable, inflatable motor switch. 5.RS1 and RS2 is the regulator valve from the land 6.RS3 synchronous motor with the valve, the valve motor is rotating circle the number of sensors. 7.RS4 delay time to regulate land

keil c51在编译的时候会将0xfd的字符(有些汉字含该字符的内码)过滤, 而导致程序出错.特别是在做液晶汉字显示时. 针对这个bug.由网友编写了这个补丁. 请下载之后放到你的keilc51in 目录里,运行这个程序.就可以了. 支持v8.02-keil c51 will be at compile time 0xfd characters (some characters with the character code) filter, which led to error. particularly in the so LCD display Chinese characters. To address this bug. prepared by the users of the patch. Please after download put your keil c51 bin directory, run the process. it. support v8.02
