ads7843触摸屏接口的一种应用设计-ads7843 touch-screen interface design of an application

MEGA16 驱动开发板上的继电器,按不同的独立键，交替改变继电器开关状态-mega16 drive PWM

l298调 速 程 序 常规的接法是这样的，EnableA接PWM信号，Input1输入正反控制信号， Input2是Input1经过反相以后的信号。L298的电平是与TTL电路相兼容的，一般是超过2.5V就为高电平。假如Input1为高电平时电机正转，那么低电平时就是反转，PWM信号控制电机的转速。 _________________ -l298 procedures conventional speed connection that is the case, EnableA then PWM signal, Input1 input positive and negative control signals, Input2 is Input1 through after RP signal. L298 level is compatible with TTL circuits, and is generally more than 2.5V for the high. If Input1 is high when the motor is transferred, then that is when low-level inversion, PWM signal to control motor speed. _________________

利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，实现主支路路口的交通信号灯控制（尽可能保持主线的畅通，即在通常情况下，保持主线的放行，只有在支线到达时，才放行支线），同时采用LCD显示倒计时时间及当前灯的状态-The use of MCU timer timing, so that the crossroads at the traffic lights turn out light and to achieve the main slip road junction traffic lights control (as far as possible the smooth flow of the main line, that is, under normal circumstances, to maintain the release of the main line, and only arrived at the branch only when the release branch), while using LCD display countdown time and the current state of light

51单片机读写SD列子程序 可以学习51单片机如何读写SD卡-51 Singlechip Liezi SD procedures to read and write can learn how to read and write 51 Singlechip SD Card

基于51单片机系统，实现能用接口1602 LCD的显示现控制。电脑主机通过串口给51发送控制指令，51根据指令对LCD进行相应的控制与显示操作。编程环境：Keil-Based on 51 single-chip system, 1602 LCD interface can display the current control. Mainframe computer through the serial port to send control commands 51, 51 follow the instructions on the LCD for the corresponding control and display operations. Programming Environment: Keil

串口双工通讯，单片机上用LCD显示主机发送的数据，同时可以通过单片机的按键向主机发送多种数据-Duplex serial communication, single-chip LCD display with a host to send data at the same time can be key to the host MCU to send multiple data

基于无线单片机24e1的组网程序。在无线传感器之类的应用中的成功案例。-microcontroller based wireless network 24e1 the procedure. In wireless sensor applications such as a successful case.
