ADC-and-LCD

使用AT89C52单片机开发，功能是控制直流电机运行，可调速。(Developed with AT89C52 single chip computer, the function is to control the operation of DC motor and speed regulation.)

AD7547 12位DA转换心片，用法很简单，很好用，(AD7547 12 bit DA converter Tablets, usage is very simple, very good, and)

说明：  本例程演示用汇编语言驱动DA,主要是针对51单片机的(This example shows using assembly language driver DA, mainly for 51 single)

基于瑞萨单片机，R8C/25的UART通讯程序，针对KEYPAD上位机开发的通讯程序，包含校对。(R8C/25 UART0)

两个HP忆阻器的SPICE模型，可以设置P等参数。(Two HP memristor SPICE model parameters can be set P)

P1口扩展实验 P1口既做输入口又做输出口，KEY1做为左转弯开关，KEY2做为右转弯开关。LED5、LED6做为左转弯灯，LED7、LED8做为右转弯灯（如图2-2）。 编程实现汽车转向灯功能，即：KEY1接高电平KEY2接低电平时，右转弯灯灭，左转弯灯以一定频率闪烁（注意：KEY拨向上方为0）；KEY2接高电平KEY1接低电平时，左转弯灯灭，右转弯灯以一定频率闪烁；KEY1、KEY2同时接低电平时，发光二极管全灭；KEY1、KEY2同时接高电平时，发光二极管全亮。(P1 I extended not only to do experiments P1 I also do input output, KEY1 switch as a left turn, KEY2 as switches and turn right. LED5, LED6 as a left turn lights, LED7, LED8 as lights and turn right (Figure 2-2). Programming car turn signal function, namely: KEY1 high key2 access low-level access, the right turn lights out, left turn to a certain frequency of flashing lights (Note: KEY allocated to the top to 0) KEY2 access high Key1 low-level access, the left turn lights out, turn right to a certain frequency of flashing lights KEY1, KEY2 low at the same time, the light-emitting diode body KEY1, KEY2 high at the same time, the light-emitting diode light-wide.)

数字温湿度传感器SHT1X中文器件手册（PDF及DOC），还包括SHT1X的51例程。SHT1X开发必备。(Digital temperature and humidity sensor device SHT1X Chinese Manual (PDF and DOC), also includes SHT1X 51 routines. SHT1X development essential.)
