IIC读写的例子，符合标准协议的写法！

这是一个1200波特的FSK调制解调器的源代码，并创建了代码中的基于PWM正弦波发生器使用的AVR库。我用ATMEL ATMEGA2313微控制器和从PWM输出引脚ATMEGA2313，我产生一个PWM信号。PWM信号是DDS的形式（直接数字合成），所以如果您的PWM输出连接到一个简单的低通滤波器就可以达到很好的正弦波。它的测试和应用代码。祝好运。

你可曾经为硬件看门狗的复位时间太短,而苦恼过,这个方法帮你解决问题. 用定时器喂狗,如果超过一定时间(程序跑飞,或整个中断都关闭,都会导致定时器不喂狗,导致看门狗的复位,从而延长了看门狗的复位时间)不喂就复位. 程序中我以lcpRD2为例.-you may have to reset the hardware watchdog short time and anguish that this approach help you solve the problem. DOG with timers, if more than a certain time (running fly procedures, or were closed throughout the interruption, it will not lead to the timer DOG, resulting in the reduction watchdog, thereby prolonging the watchdog reset the time) do not feed on the reset. proceedings I lcpRD2 example.

Part I We wish to display on the 7-segment displays HEX3 to HEX0 the values set by the switches SW15−0. Let the values denoted by SW15−12, SW11−8, SW7−4 and SW3−0 be displayed on HEX3, HEX2, HEX1 and HEX0, respectively. Your circuit should be able to display the digits from 0 to 9, and should treat the valuations 1010 to 1111 as don’t-cares. 1. Create a new project which will be used to implement the desired circuit on the Altera DE2 board. The intent of this exercise is to manually derive the logic functions needed for the 7-segment displays. You should use only simple VHDL assignment statements in your code and specify e
