This will sample all 8 A/D-channels by the continous mode. Each end of conversion will call an interrupt routine, where the AD-channel is put to Port4[2..0] and the upper nibble of the result is put to Port4[7..4]. Port 4 is connected to the user LEDs of the FlashCan100P Evaluation-Board

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

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.

Implement the following integer methods: a) Method celsius returns the Celsius equivalent of a Fahrenheit calculation celsius = 5.0 / 9.0 * ( fahrenheit - 32 ) b) Method fahrenheit returns the Fahrenheit equivalent of a Celsius the calculation fahrenheit = 9.0 / 5.0 * celsius + 32 c) Use the methods from parts (a) and (b) to write an application either to enter a Fahrenheit temperature and display the Celsius or to enter a Celsius temperature and display the Fahrenheit equivalent.

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。

这是编译原理的一个实验, 是把一个正则表达式转化为不确定有穷自动机NFA的算法程序,朋兴趣的朋友可以下载来看看哦。 一个正则表达式就是由普通字符（例如字符 a 到 z）以及特殊字符（称为元字符）组成的文字模式。该模式描述在查找文字主体时匹配的一个或多个字符串。正则表达式作为一个模板，将某个字符模式与所搜索的字符串进行匹配。 本实例的符号包括： 1. 基本正则表达式, 如ab 2. 重复, 如a* 3. 在各项中选择, 如a|b 使用时在Convert的Reg Exp中点击输入正则表达式, 然后单击Convert->to NFA就可以了。

T-kernel 的extension源代码，是日本最著名的T-kernel所独有的，适合开发T-kernel的朋友们使用！ TK/SE is the program that extends T-Kernel and provides the functions such as a file system and a process management. The TK/SE archive to be provided is comprised of the main portion and the 2 extended file system portions, and TK/SE object is built by adding these to T-Kernel source. a) tkernel_se_1.00.00.tar.gz Main source of T-Kernel/SE b) extfs_fatfs_1.00.00.tar.gz Difference source of T-Kernel/SE extended file system (FAT) c) extfs_cdrom_1.00.00.tar.gz Difference source of T-Kernel/SE extended file system (CD-ROM)
