基于电脑USB的按摩器,包括原理图和源程序下载,单片机用的是PIC12F629...

在单片机系统中实现4*4的小键盘的扫描程序，按键输出对应信号，可以根据按键来设定输出对应高低电平-Single-chip microcomputer system in the implementation of the 4* 4 keypad scanning procedures, the corresponding button output signal can be output in accordance with the corresponding button to set the high-low

基于PIC18F2580实现的 1602LCD显示程序 只用4个数据口-Based on the PIC18F2580 realize 1602LCD display program only 4 data port

单片机控制的步进电机 不是很完善 但是能实现基本功能-Single-chip stepper motor control is not very perfect but can realize the basic functions of

尽量朝“单片”方向设计硬件系统。系统器件越多，器件之间相互干扰也越强，功耗也增大，也不可避免地降低了系统的稳定性。随着单片机片内集成的功能越来越强，真正的片上系统SoC已经可以实现，如ST公司新近推出的μPSD32××系列产品在一块芯片上集成了80C32核、大容量FLASH存储器、SRAM、A/D、I/O、两个串口、看门狗、上电复位电路等等。 -North Korea as the "single-chip" design direction of the hardware system. System devices more mutual interference between devices are more strong, power consumption is increased, it will inevitably reduce system stability. With MCU with on-chip integration of more powerful, the real system-on-chip SoC can achieve, such as ST"s new PSD32 x x in a series chip integrates exertion nuclear, large-capacity flash memory, SRAM, A/D, I/O, 2 serial port, watchdog, the power-on reset circuit and so on.
