Description: 在UP3开发板上已经验证过的VHDL代码。精确到十分之一秒，具有闹钟，整点报时，时间可重新设置等功能，在LCD1602上显示。绝对推荐，比网上其他类似代码功能要全而且经过验证。最关键的是该代码是直接通过I2C总线来获取UP3开发板上的实时时钟芯片的时间的,当然也可以通过I2C对时钟芯片进行设置.-In the UP3 development board has been verified VHDL code. Accurate to one-tenth of seconds, with the alarm clock, the whole point timekeeping, time and other functions can be re-instated in the LCD1602 display. Absolutely recommended online than other similar features to the entire code and verified. Most crucial point is that the code is directly through the I2C bus to obtain the UP3 development board real time clock chip time, of course, can also I2C clock chip on the set.

Description: *** ***OC_I2C_Master使用说明*** *****
使用步骤：1.将OC_I2C_Master文件夹拷贝到安装盘\altera\kits\nios2\components目录下。
之后重新打开SOPC Builder，在可用元件列表的DeviceSOPC组中将出现OC_I2C_Master
元件，即可像其它Altera外设元件一样添加和使用。
2.hdl文件夹中包含有描述i2c逻辑的硬件描述文件，不能删除。
3.HAL文件夹包含硬件抽象层所需的文件（即驱动），不能删除。
4.inc文件夹包含有定义底层硬件的C语言头文件，不能删除.
5.I2C_doc文件夹下有关于该元件的开发文档。-********* OC_I2C_Master use*********** use these steps: 1. OC_I2C_Master folder will be copied to the installation disk alterakits ios2components directory. Re-open after the SOPC Builder, a list of available devices will appear DeviceSOPC Group OC_I2C_Master components, can be similar to other peripheral devices like Altera add and use. 2.hdl folder contains logical description i2c hardware description files, can not be deleted. 3.HAL folder contains the necessary hardware abstraction layer file (ie drivers), can not be deleted. 4.inc folder contains the definition of the underlying hardware C language header files, should not delete. 5.I2C_doc folder on the development of document components.

Description: pmbus在avr32开发板平台上tiny24中的实现。-This is PMBus 1.1 [0] software intended to replace the firmware found in the "Board Controller" [1] on the Atmel ATNGW100 [2], which is a low cost [$US 90] Linux-oriented board suitable for developing and deploying AVR32 based embedded systems. This firmware can go into an ATtiny24 microcontroller which is found on that board, but which is not currently used for anything of note.
This is licensed under GNU GPLv3. The distribution files include
README-- what you re reading
COPYING-- copy of GPLv3
Makefile-- to build under Linux
pmbus_slave.elf-- pre-built binary
pmbus_peek.c-- userspace tool talking to the firmware
Plus of course the source code with the I2C/PMBus protocol code and microcontroller access:
main.c
pmbus.c
usi_i2c_slave.c
usi_i2c_slave.h
smbus_glue.h
prod_misc.h

Description: 猜数字游戏机
这是一个让玩家在一定的规则和系统提示下，推算一个随机产生的四位数的游戏，这个四位数的各位都不相同。游戏规则如下：
系统 随机产生一个四位数，数码各不相同，玩家通过键盘依次输入4位数，输错可以按退格键修改，输完按确认键确认，然后系统判断，如果猜的数字有x个数字与答案数码相同并且位置相同（该条件代号用A表示），有y个数字与答案数码相同但位置不同（该条件代号用B表示），就输出xAyB。例如答案是2639，输入1692，那么确认后显示结果1A2B。然后玩家通过分析再次输入新的数字，直到猜中答案。游戏每局提供10次机会，并且有100秒倒计时，以增加玩家的压力。
本系统采用CPLD作为主控平台，另外用单片机通过I2C总线与单片机通信实现4个数码管的输出。
-Number guessing game
This is a must for players in the rules and the system prompt, the projection of a randomly generated four-digit game, the four digits of you
Not the same. Rules of the game are as follows:
System generates a random four-digit, different digital players followed by the keyboard input 4-digit, the wrong can press the backspace key repair
Changed, losers press the Enter key to confirm, then the system to determine if there are x number of guess the number and location of same with the same answer to digital (which
Pieces of code that with A), y have the same numbers but with different positions of digital answer (indicated with B in the condition code), the output xAyB. Such as
The answer is 2639, enter 1692, then display the results confirmed 1A2B. Then the player by analyzing the re-enter the new number until guess
The answer. Board games every 10 chances, and 100-second countdown to increase the pressure on the players.
The system uses the CPLD as a host

Description: ARM-M0-LPC1114 I2C串口通讯程序-From device to device, the I2C communication protocol may vary,
in the example below, the protocol uses repeated start to read data from or
write to the device:
For master read: the sequence is: STA,Addr(W),offset,RE-STA,Addr(r),data...STO
for master write: the sequence is: STA,Addr(W),offset,RE-STA,Addr(w),data...STO
Thus, in state 8, the address is always WRITE. in state 10, the address could
be READ or WRITE depending on the I2C command.
