菲利普LPC900系列写Flash源码-Philippe LPC900 family was Flash FOSS

用MSP430F149控制普通射频芯片CC1000的双向通信程序（串口、液晶显示），软件按状态机原理实现，开发环境为IAR-MSP430F149 control using radio frequency chip CC1000 ordinary two-way communication process (serial, liquid crystal display), the software state machine according to the principle of implementation and development environment for the IAR

c嵌入式编程经验，很有价值，有需要的可以参考-good source for embedded program

CRC校验采用多项式编码方法。多项式乘除法运算过程与普通代数多项式的乘除法相同。多项式的加减法运算以2为模，加减时不进，错位，如同逻辑异或运算。-CRC polynomial used coding method. Polynomial multiply and divide computing process and the general polynomial algebra multiply and divide the same. Polynomial and subtract operations for the two to die, not into the Modified, dislocation, as logical XOR.
