12864液晶中文资料(电路,程序,图片）

带中文字库的128X64是一种具有4位/8位并行、2线或3线串行多种接口方式，内部含有国标一级、二级简体中文字库的点阵图形液晶显示模块；其显示分辨率为128×64, 内置8192个16*16点汉字，和128个16*8点ASCII字符集.利用该模块灵活的接口方式和简单、方便的操作指令，可构成全中文人机交互图形界面。可以显示8×4行16×16点阵的汉字. 也可完成图形显示.低电压低功耗是其又一显著特点。由该模块构成的液晶显示方案与同类型的图形点阵液晶显示模块相比，不论硬件电路结构或显示程序都要简洁得多，且该模块的价格也略低于相同点阵的图形液晶模块。基本特性: 低电源电压（VDD:+3.0--+5.5V）显示分辨率:128×64点内置汉字字库，提供8192个16×16点阵汉字(简繁体可选) 内置 128个16×8点阵字符 2MHZ时钟频率显示方式：STN、半透、正显驱动方式：1/32DUTY，1/5BIAS 视角方向：6点背光方式：侧部高亮白色LED，功耗仅为普通LED的1/5—1/10 通讯方式：串行、并口可选内置DC-DC转换电路，无需外加负压无需片选信号，简化软件设计工作温度: 0℃ - +55℃ ,存储温度: -20℃ - +60℃ 12864（带字库汉字显示演示程序）

基于C8051F060单片机控制AD9833实现FSK调制

引言在数字信息传输中，基带数字信号通常要经过调制器调制，将频率搬移到适合信息传输的频段上。2FSK就是用数字信号去调制载波的频率（移频键控），由于它具有方法简单、易于实现、抗噪声和抗衰落性能较强等优点，因此在现代数字通信系统的低、中速数据传输中得到了广泛应用。直接数字频率合成技术(DDS)将先进的数字处理技术与方法引入信号合成领域。DDS器件采用高速数字电路和高速D/A转换技术，具备频率转换时间短、频率分辨率高、频率稳定度高、输出信号频率和相位可快速程控切换等优点，可以实现对信号的全数字式调制。

采用高速串行收发器Rocket I/O实现数据率为2.5 G

摘要: 串行传输技术具有更高的传输速率和更低的设计成本, 已成为业界首选, 被广泛应用于高速通信领域。提出了一种新的高速串行传输接口的设计方案, 改进了Aurora 协议数据帧格式定义的弊端, 并采用高速串行收发器Rocket I/O, 实现数据率为2.5 Gbps的高速串行传输。关键词: 高速串行传输; Rocket I/O; Aurora 协议为促使FPGA 芯片与串行传输技术更好地结合以满足市场需求, Xilinx 公司适时推出了内嵌高速串行收发器RocketI/O 的Virtex II Pro 系列FPGA 和可升级的小型链路层协议———Aurora 协议。Rocket I/O支持从622 Mbps 至3.125 Gbps的全双工传输速率, 还具有8 B/10 B 编解码、时钟生成及恢复等功能, 可以理想地适用于芯片之间或背板的高速串行数据传输。Aurora 协议是为专有上层协议或行业标准的上层协议提供透明接口的第一款串行互连协议, 可用于高速线性通路之间的点到点串行数据传输, 同时其可扩展的带宽, 为系统设计人员提供了所需要的灵活性[4]。但该协议帧格式的定义存在弊端,会导致系统资源的浪费。本文提出的设计方案可以改进Aurora 协议的固有缺陷,提高系统性能, 实现数据率为2.5 Gbps 的高速串行传输, 具有良好的可行性和广阔的应用前景。

lpc2292/lpc2294 pdf datasheet

The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct with minimal performance penalty. With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available fast GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary.
