AVR 单片机系列齐全,可适用于各种不同场合的要求。AVR 单片机有 3 个档次: 低档Tiny 系列AVR 单片机: 主要有Tiny11/12/13/15/26/28等; 中档AT90S系列AVR 单片机: 主要有AT90S1200/2313/8515/8535 等; (正在淘汰或转型到 Mega中) 高档ATmega系列AVR 单片机: 主要有ATmega8/16/32/64/128 (存储容量为 8/16/32/64/128 KB) 以及ATmega8515/8535等。 AVR 器件引脚从 8 脚到 64 脚, 还有各种不同封装供选择。 推荐初学者选择学习的芯片型号是ATmega48/88/168 或者 ATmega16;不推荐使用中档的AT90S系列,因为它们都是比较早期的产品,早已经停产了。

I often need a simple function generator. Just to generate a certain frequency. After all the years I ve worked with electronics, I still haven t got me one. Even though I need it now and then, I just couldn t seem to justify the cost of one. So, standard solution - build one yourself. I designed a simple sinewave generator based on a Analog Devices AD9832 chip. It will generate a sinewave from 0.005 to 12 MHz in 0.005 Hz steps. That s pretty good, and definitely good enough for me ! But while waiting for the AD9832 chip to arrive, I came up with a very simple version of the DDS synth, using just the 2313 and a resistor network.
