PIC单片机控制12位高速串行DA（max538）产生阶梯波

TCP/IP 协议栈成功的在S3C44B0X 的实现。我从网上下的所谓在44b0x上运行的tcpip程序其实都是不能运行的，包括LWIP在44b0x代码。这个是我自己根据下载的代码经过努力的修改和调试得到的，程序稳定，TCP UDP ICMP web都得到很好的实现。os是UCOS-II.程序包里面有详细的程序演示说明-TCP/IP protocol stack S3C44B0X successfully realized. I am from the Internet under the so-called 44b0x running tcpip procedures are actually not running, including lwIP in 44b0x code. This is my own code under the download through efforts to modify and debug obtained, procedures stability, TCP UDP ICMP web have been very good to achieve. os is UCOS-II. package there are detailed procedures Demo Description

使用STM32f407移植FATFS文件系统，最新版本R0.10。底层采用SDIO四线驱动，DMA传输数据，速度可以达到1M/s。需要注意的是，发送和接收的数据缓冲区的地址需要是四字节对齐的，也就是说它的起始地址需要是4的倍数，否则会出现读写错误的现象。
