This example describes how to use the ADC and DMA to transfer continuously converted data from ADC to a data buffer. The ADC is configured to converts continuously ADC channel14. Each time an end of conversion occurs the DMA transfers, in circular mode, the converted data from ADC1 DR register to the ADC_ConvertedValue variable. The ADC1 clock is set to 14 MHz.

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

在DEBUG状态下，显示中断向量表，找一个空闲的中断类型号，以此软中断作为新增加的系统调用中断。编制一个系统调用服务与初始化程序syscall.asm，要求包括以下两部分内容：① 系统调用服务例程；② 初始化程序：设置新的中断向量和驻留新增加的例程。编制一个用户程序user.asm，其目的是检测新增加的功能调用是否成功。在DEBUG状态下：① 查找中断向量表中新增加的系统调用的中断向量；② 显示扩充的中断服务例程；③ 找到该中断服务例程中使用的数据区。

a screen handling program to provide a flashing message. You will have to design a screen layout for where messages are placed on the screen. You will also have to consider when to delay the program in order to give the user time to read the messages. That is, the program will use the curses library, signals and the sleep function.

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。
