It was a ATmega128 Sleep mode and awake mode programed by avr studio4

数字量-模拟量转换器，可以实现单片机处理的数字量信号转换成模拟量电压电流信号输出(Digital analog converter)

主要是完成Listctr的封装,和对于xlistctrl 的一个实例程序 (The main package is completed Listctr)

单片机程序，可以用单片机控制，在12864液晶屏上显示一幅图画。文件中有显示所用的代码。(Microcontroller program, you can use single-chip control, in 12864 a picture displayed on the LCD screen. Documents showing the code used.)

AES128/196/256 加解密源码，可实现ECB模式加密，HEX输出。密码及明文没有补齐功能，需手动补齐。无需特殊库文件，适合单片机使用。已测试，可正常使用。(AES128/196/256 encryption source code, can achieve ECB mode encryption, HEX output. The password and the plaintext without the need to manually fill up function. No special library files, suitable for single use. Has been tested, can be used normally.)

51单片机的4x4键盘扫描c语言程序，大家看看，(51 single-chip 4x4 keypad scan, we look)

通过把开机次数记录在24C02中，并在数码管上显示出来， 124C02的写保护脚为低电平，即允许写(Boot number of records in the 24C02, and displayed on the digital 124C02 write-protect pin is low, that is allowed to write)

关于51单片机和dac7811芯片之间通信的程序，可以正确模拟SPI串口通信，写入数据(On communication between 51 single chip microcomputer and dac7811 chip procedures, can correctly simulate the SPI serial communication, write data )

　Hittite公司以创新的设计使得其PLL产品性能优异，在相位噪声，杂散方面有着卓越表现，其芯片的高集成度使得外围电路简单，设计方便。所以随着电子技术的发展，对频率源的相位噪声性能要求越来越高，Hittite的低相位噪声PLL，在物理、天文、无线电通信、雷达、航空、航天以及精密计量、仪器、仪表等各种领域里都将大有用武之地。(The Hittite companies with innovative design makes the PLL excellent product performance, the phase noise, spurious aspects with excellence, its high integration chip makes the peripheral circuit is simple and easy design. So with the development of electronic technology, phase noise performance of frequency source is more and more high, the Hittite low phase noise PLL, in physics, astronomy, radio communication, radar, aviation, aerospace and precision measurement, instruments, meters and other fields will be great.)
