led -位操作

Useful modding - a spectrum analyzer + clock. We came across two 5x8 LED matrix, virtually occupying five-inch drive bay, and I decided to make a spectrum analyzer based on their sound.

利用单片机MSP430f149单片机实现的 实验十二 SPI接口扩展RF通信(The use of single-chip MCU MSP430f149 Experiment 12 SPI interface extensions RF communications)

This program operate mathematic functions on numbers

说明：  改程序可简单的产生从0到f的递增数码管显示，着为初学者提供比较好的认识。(Reform program can generate a simple increments from 0 to f, digital tube display, forward to providing a better understanding of beginners.)

说明：  实现ads1110电压模数转换和lcd1602显示以及电阻测量(ADS1110 voltage analog-to-digital conversion and LCD1602 display and resistance measurement)

32 F429同时使用定时器2和4实现中断控制LED0和1闪烁(USING TIM2 AND TIM4 IN THE MEANWHILE)

CRLB理论测试精度，用于实现蜂窝网无线定位算法及其仿真~(CRLB theory test accuracy)
