进行arm－linux嵌入式系统开发时，需要将文件烧写到flash上，在网上可以找到win下的烧写程序，但多数情况下开发环境应该是在linux下，烧写程序时切换到win下很不方便，使用该程序可以在linux下直接对flash进行烧写 该程序运行后将一个小的for arm的c程序通过串口传送到arm开发板上，使用该小程序与主机端通信，将主机传送信息烧写到flash上- Carries on when arm- linux inserts the type system development, needs the document fever to write on flash, is on-line may find under win the fever to write the procedure, but in the most situations the development environment should be under linux, the fever writes when the procedure cuts under win not to be very convenient, uses this procedure to be allowed directly to carry on the fever under linux after flash to write this procedure movement to transmit orally a small for arm c procedure through the string delivers on the arm development board, uses this script and the main engine end correspondence, writes the main engine pass-along message pam fever on flash

主要是关于msp430设计的血氧相关程序，包含具体的驱动啊，算法啊 

本程序是通过TMS320CS2047的DSP处理器,经过DSP内部事件管理器的配合,实现SPWM波输出!-This procedure is adopted TMS320CS2047 of DSP processors, DSP, after the internal event manager with the realization of SPWM wave output!

很好的例程 包含sci 等外设 module i2c_master_model (scl, sda); inout scl; inout sda; parameter slave_addr_reg = 7"b0110101; //slave addr int i; reg R_scl   = 1"bz; reg R_sda  = 1"bz; reg clk = 0; always #(1329.1125) clk = !clk; assign scl = R_scl; assign sda = R_sda;

s3c2410提供了5个16位的Timer（Timer0~Timer4），其中Timer0~Timer3支持Pulse Width Modulation―― PWM（脉宽调制 ）。Timer4是一个内部定时器（internal timer），-S3C2410 provides five 16-bit Timer (Timer0 ~ Timer4), which Timer0 ~ Timer3 support Pulse Width Modulation- PWM (Pulse Width Modulation). Timer4 is an internal timer (internal timer),
