用诺基亚5110显示的悬挂运动控制系统，完美的运行了寻点，直线，画圆，循迹的程序没加进去，如果想要的话发信息至1551142817@qq.com(Nokia 5110 display with a suspension motion control system, running to find the perfect point, line, circle, tracking program not added, if desired send a message to 1551142817@qq.com)

深圳峰岹FU68XX IC 做的电动工具方案。开发平台：Keil.(this is a program of battery powered tool, you can find the setting for TIMER,PWM,EEPROM and IO , it was complied on Keil and it is very useful.)

说明：  使用555时基电路产生频率为20kHz-50kHz的方波Ⅰ作为信号源；利用此方波Ⅰ，可在四个通道输出4种波形；每通道输出方波Ⅱ、三角波、正弦波Ⅰ、正弦波Ⅱ中的一种波形，每通道输出的负载电阻均为600欧姆。限用NE555、NE5532（或LM358）、电容和电阻若干。(-Waveform generator with schematic + circuit + program)

关于STM32F407的IIC总线操作，用IO口模拟总线时序，以及AT24C64的驱动编写。(The IIC bus operation on STM32F407 with analog IO bus timing, and write AT24C64 drive.)

数模转换芯片DA0832直通方式驱动一个发光二极管，由暗到亮循环( )

说明：  该程序是为大家提供简单的AD程序,实现AD转换(This program is to provide you with a simple AD program to achieve AD conversion.)

说明：  单片机MC9S08AW60脉宽调制 TPM1CH3 LS2亮度控制 KBI SEG控制亮度等级 。本工程为定时器输出PWM波测试工程实例通过对PWM占空比的调节,实现小灯的渐亮的功能,当占空比为100％时再从0％逐渐增加.PWM的周期一定要足够的快,否则其输出电压的波动范围很大,且测不出一个稳定的电压值,这样通过就观察不到小灯渐亮效果. 另外,在改变PWM的周期和占空比之前和之后要分别禁止和使用。(MC9S08AW60 pulse width modulation TPM1CH3 LS2 brightness control KBI SEG brightness level. This project is an example of testing the output PWM wave of the timer. By adjusting the duty ratio of the PWM, the function of the small lamp gradually brightening is realized. When the duty ratio is 100%, the period of the small lamp gradually increases from 0%. The period of the PWM must be fast enough. Otherwise, the fluctuation range of the output voltage is large and a stable voltage value can not be measured, so the effect of the gradual brightening of the small lamp can not be observed. In addition, the period of the PWM is changed. Before and after duty cycle should be prohibited and used separately.)
