PIC单片机在直流电机无级调速系统的设计

现代工业生产中，电动机是主要的驱动设备，目前在直流电动机拖动系统中已大量采用晶闸管(即可控硅)装置向电动机供电的KZ—D拖动系统，取代了笨重的发电动一电动机的F—D系统，又伴随着电子技术的高度发展，促使直流电机调速逐步从模拟化向数字化转变，特别是单片机技术的应用，使直流电机调速技术又进入到一个新的阶段，智能化、高可靠性已成为它发展的趋势。本调速系统采用PIC16F874单片机作为中心处理器，充分利用了PIC16F874单片机捕捉、比较、模/数转换模块的特点作为触发电路，其优点是：结构简单，能与主电路同步，能平稳移相且有足够的移相范围，控制角调整量可达10000步，能够实现电机的无级平滑控制，脉冲前沿陡且有足够的幅值，脉宽可设定，稳

利用PIC单片机让LCD闪烁

　　使用 LCD 面板，信息可以通过多种方式显示。例如，如何将用户的注意力吸引到LCD面板的特定部分？一种不需要任何附加段的方式是产生闪烁效果。　　以常见的时钟(见下图)应用为例。小时和分钟之间的“：”通常每秒闪烁一次（显示半秒，隐藏半秒）。　　在缺少滴答声或通常伴随模拟外观时钟的秒针时，这可以显示时钟正在计时。它起到一种重要的作用，让用户知道时钟正在工作。　　如果电源的电能即将耗尽，则通常整个时钟显示会开始闪烁。这使用户可以立即了解时钟不再显示正确的时间。　　在用户设置时间时，通常使用闪烁来显示已进入了新模式，例如闪烁小时来指示正在设置小时，或者闪烁分钟来指示正在设置分钟。在简单时钟中，闪烁用于多种不同用途。如

PIC单片机开发过程中软、硬件设计一些经验、技巧

本文总结了作者PIC单片机开发过程中一些经验、技巧，供同行参考。 1 怎样进一步降低功耗功耗，电池供电仪器仪表中是一个重要考虑因素。PIC16C 系列单片机本身功耗较低（5V，4MHz振荡频率时工作电流小于2mA）。为进一步降低功耗，保证满足工作要求前提下，可采用降低工作频率方法，工作频率下降可大大降低功耗（如PIC16C 3V，32kHz下工作，其电流可减小到15 A），但较低工作频率可能导致部分子程序（如数学计算）需占用较多时间。这种情况下，当单片机振荡方式采用RC电路形式时，可以采用中途提高工作频率办法来解决。具体做法是闲置一个I/O脚（如RB1）和OSC1管脚之间跨接一电阻（R1），如图1所示。低速状态置RB1=0。

PIC单片机I2C的应用（24LC02）

I2C总线特点 I2C总线最主要的优点是其简单性和有效性。由于接口直接在组件之上，因此I2C总线占用的空间非常小，减少了电路板的空间和芯片管脚的数量，降低了互联成本。总线的长度可高达25英尺，并且能够以10Kbps的最大传输速率支持40个组件。I2C总线的另一个优点是，它支持多主控(multimastering)，其中任何能够进行发送和接收的设备都可以成为主总线。一个主控能够控制信号的传输和时钟频率。当然，在任何时间点上只能有一个主控。 2 I2C总线工作原理 I2C总线上的数据稳定规则，SCL为高电平时SDA上的数据保持稳定，SCL为低电平时允许SDA变化。如果SCL处于高电平时，SDA上产生下降沿，则认为是起始位，
