19264液晶屏与单片机驱动-电子工程世界

分享到: 微博; QQ; 微信; LinkedIn

首先说下19264屏

1926屏是由3个64*64 组成 64行 192列其中192列是64+64+64 =192

它们分别有CS1 CS2 CS3 控制让那个屏显示所以每个屏最多只能显示64行64列切结8行等于1页。

每页只能最多写8行 64列，8*64 =512位 512/8 =64字节最多写64字节。。以上就是19264液晶屏的基本原理，虽然各个厂商硬件有所差异但原理基本相同。

以下给之前项目中使用的AT-C19264的驱动部分代码仅供参考！

STM8单片机串口驱动的深度解析

串口是单片机最重要的外设之一，在很多项目开发中都有应用，Lora模块的外部通讯方式就是串口。本节简单的和大家解析一下串口通讯及驱动代码的编程。 STM8L101F3单片机支持一路串口通讯。我们先看一下Lora模块的硬件接口，如下图所示: 串口的硬件接口是PC2 和PC3两个脚位。下面开始讲解软件部分，这块我们无际单片机编程也有这个项目全部视频教程，下面是文字版。软件驱动 STM8打开标准库文件夹，打开串口USART例程: 2.如上图所示，是标准库中串口通讯的的例程，并选择第一个例程。 3.我们按照之前的方式，把USART_HyperTerminalInterrupt文件复制到ProjectSTM8

手把手教你使用PIC单片机驱动继电器

在现代自动控制设备中，都存在一个电子电路（弱电）与电气电路（强电）的互相连接问题，一方面要使电子电路的控制信号能够控制电气电路的执行元件（如电动机、电磁铁、电灯等），另一方面又要为电子线路的电气电路提供良好的电隔离，以保护电子电路和人身的安全。继电器便能完成这一桥梁作用。继电器的工作原理与分类继电器是一种电子控制器件，它具有控制系统（又称输入回路）和被控制系统（又称输出回路），通常应用于自动控制电路中，它实际上是用较小的电流去控制较大电流的一种“自动开关”。故在电路中起着自动调节、安全保护、转换电路等作用。在大多数的情况下，继电器就是一个电磁铁，这个电磁铁的衔铁可以闭合或断开一个或数个接触点。当电磁铁的绕组中有电流通过

STC15单片机驱动WS2812B七彩LED（汇编混合编程）

WS2812B七彩LED具有集成度高、使用方便等特点，但是800K的数据速率（IO变化速率高达2.4M），对单片机提出了较高的要求，通常是采用SPI+DMA方式驱动，也有人采用汇编实现，但是要预先把数据转换为按bit存放，在LED级连数量较多的情况下，需要占用极多的存储空间。在驱动WS2812B上花费了太多的时间，走了不少弯路，记录下来：简易数字分析仪采样频率最高只有4M，即测量精度为250ns，而信号宽度要求为400ns和850ns，这样测量的结果存在较大的误差，让人误以为信号跳变无规律，迷失了方向；解决的办法就是利用STC单片机主时钟的内分频功能，语句：CLK_DIV |= 0x07; 将主频降低128倍，

基于ADC081S051与51单片机的接口电路及驱动程序

　　引言　　自然界存在的信号通常为模拟信号，在测控系统中通常将采集到的模拟信号数字化，然后交给微处理器或微控制器进行处理。因此模数转换器成为测控系统中不可缺少的部分。ADC081S051 模数转换器是国家半导体公司生产的低功率单通道CMOS 8位A/D转换器，它采用串行外设接口方式进行数据输出。与传统的器件不同的是，传统器件的采样速率是固定的，而ADC081S051 的采样速率可以在200~500 KSPS 范围内可变。　　ADC081S051 的数据输出是串行数据输出，它与SPI、QSPI 等一些标准相兼容。它的工作电压范围在2.7~5.25 V,因此可以采用3 V或者5 V电源供电。它可以应用于便携式系统、远程数据采集
