This example provides a description of how to use a DMA channel to transfer a word data buffer from memory (Flash) to memory (RAM). The dedicated DMA channel is configured to transfer once a time a 32 word data buffer stored as constant in the Flash memory to another buffer in the RAM memory. The received data are stored in the DST_Buffer. The DMA channel transfer complete interrupt is enabled to generate an interrupt at the end of the buffer transfer. As soon as the transfer is completed an interrupt is generated and in the DMA channel interrupt routine the transfer complete interrupt pending bit is cleared. The data counter is stored before and after the transfer to show that all data has been transfered. TransferStatus gives the data transfer status where it is PASSED if transmitted and received data are the same otherwise it is FAILED

基于UDP实现E-Mail传输 工作过程描述： 客户端描述： 1． Client（以下简称C端）端将邮件以规定的大小封装为符合要求的UDP包。 2． 将封装好的UDP包发出，并等待Server(以下简称S端)端收到相应的UDP包后返回的回应Acknowledge(以下简称为ACK)。若收到的为Positive ACK,则继续发包；若收到的为Negtive ACK,则将应发的包重发。 3． 直到C端将所有要发的包都发完，并都已经收到S端的回应，最后发一个End包，直接关闭此进程。 服务器端描述： 1． S端启动服务进程，并监听相应端口。 2． 若收到C端发出的有关请求，按如下情况给出相应的反映： a． 将收到的包进行检测，若收到的包有错则抛弃（discard），并发给C端一个negtive ACK。 b． 将收到的包进行检测，若收到的包正常，则将此包进行解包，将内容输出至一临时文件；并发给C端一个positive ACK。 3．依次收到来自C断的包，直到收到end为止，并关闭此进程，转回监听状态。
