SPI

单片微型计算机简称单片机，是典型的嵌入式微控制器（Microcontroller Unit）， 单片机芯片 常用英文字母的缩写MCU表示单片机，单片机又称单片微控制器，它不是完成某一个逻辑功能的芯片，而是把一个计算机系统集成到一个芯片上。(Microcontroller chip microcomputer referred to, is a typical embedded microcontroller (Microcontroller Unit),     Single chip Commonly used letters of the abbreviation indicates MCU microcontroller, microcontroller, also known as single-chip microcontroller, it is not complete a certain logic functions of the chip, but to a computer system integrated into a single chip.)

单片机开发的最基础教程，适合初学者开发学习用途(MCU development of the most basic tutorial for beginners learning purposes)

88点阵扫描显示字模，数码管显示，通用51单片机适用(88 dot matrix display font scan, digital display, single chip for general-purpose 51)

可以用指令控制选择信道，设置发射功率，发送数据包（长度可选），接收数据包（接收时延可设），CC2430复位,内部温度传感器读取，定时器时长控制。底层函数基本做好，如果要加入新功能，可自行更改。(You can select the channel with the command control, set the transmit power, transmit data packet (lengths), receive data packets (receiver delay can be set), CC2430 reset, the internal temperature sensor reading, the timer duration control. Basic underlying function well, if you want to add new features to make changes.)

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.)
