医疗电子,血氧浓度测量模块原程序,采用430 单片机.-medical electronics, oxygen concentration measurement module program, using 430 SCM.

是一个利用单片机C语言生成各阶M序列的程序，还有发送程序-SCM is a C language generation of the M-series of procedures, there is this procedure

飞思卡尔智能车测试程序,仅仅是调试程序，没有完全通过-The test program for freescaleic interligentcar.

在汇编中按位运算很多，本人在C语言中，增加位处理函数。-In the compilation of digital computing by many, I am in the C language to increase the bit processing function.

本方法的基本思想就是利用单片机具有的PWM端口，在不改变PWM方波周期的前提下，通过软件的方法调整单片机的PWM控制寄存器来调整PWM的占空比，从而控制充电电流-The basic idea of this method is the use of microcontroller has the PWM ports, without changing the PWM square wave cycle, under the premise of the method to adjust by software MCU PWM control registers to adjust the PWM duty cycle and thus control the charge current

六位电子密码锁 采用89s52（51，52都可），4*4键盘，六个数码管，74ls04（位选），573（8D锁存器）。 说明：P2---数据（接573）―――（接数码管） P1---位选 ---（按74ls04） P0--4*4键盘 密码一次性设置（编程时写入的） 电路简单，此源程序仅供初学者学习，可自行扩展密码模块（加24C02）。 编绎软件为wave -six electronic password lock used 89s52 (can be 51, 52), 4* 4 keyboard, six digital control, 74ls04 (EC), 573 (8D latches). Note : P2-- Data (573 )---( access digital access control) P1 Choice------ (74ls04 ) P0-- 4* 4 keyboard set up a one-time password (into programming) circuit is simple, This program is for beginners learning will be able to expand password module (CO2 plus 24).
