怎么接做网站的任务,成都集团网站设计推荐,想要推广页,wordpress访问计数器LCD1602LCD1602引脚第 1 脚: VSS 为电源地 第 2 脚: VDD 接 5V 正电源 第 3 脚: VL 为液晶显示器对比度调整端,接正电源时对比度最弱#xff0c;接地时对比度最高#xff0c;对比度过高时会产生“鬼影”#xff0c;使用时可以通过一个 10K 的电位器调整对比度。 第 4 脚接地时对比度最高对比度过高时会产生“鬼影”使用时可以通过一个 10K 的电位器调整对比度。 第 4 脚RS 为寄存器选择高电平时选择数据寄存器、低电平时选择指令寄存器。 第 5 脚R/W 为读写信号线高电平时进行读操作低电平时进行写操作。当 RS 和 R/W 共 同为低电平时可以写入指令或者显示地址当 RS 为低电平 R/W 为高电平时可以读忙信号 当 RS 为高电平 R/W 为低电平时可以写入数据。 第 6 脚E 端为使能端当 E 端由高电平跳变成低电平时液晶模块执行命令。 第 714 脚D0D7 为 8 位双向数据线。 第 15 脚背光源正极。 第 16 脚背光源负极。LCD1602显示字符写时序图和读时序图读时序图 写时序图时序图的参数 根据写时序图封装LCD1602写入指令和写入数据的两个函数一些宏定义写入指令写入数据检测忙标志是否忙液晶显示模块是一个慢显示器件所以在写入每条指令或数据之前一定要确认模块的忙标志为低电平表示不忙否则此指令失效。由于BF标志位为数据线的D7引脚我们只关心D7引脚而且BF标志位为高电平时LCD1602表示忙可以利用一个while(BF)循环卡住然后不断读取数据线的D7引脚等待LCD1602不忙时硬件将BF标志位置0。LCD1602初始化8bit的LCD1602初始化延时 15ms 写指令 38H(不检测忙信号) 延时 5ms 写指令 38H显示模式设置 写指令 08H显示关闭 写指令 01H显示清屏 写指令 06H显示光标移动设置 写指令 0CH显示开及光标设置封装8bit的LCD1602初始化的函数4bit的LCD1602初始化延时 50ms发送 0x03(4bit)(rs0,rw0)延时 4.5ms发送 0x03(4bit)(rs0,rw0)延时 4.5ms发送 0x03(4bit)(rs0,rw0)延时 150μs发送 0x02(4bit)(rs0,rw0)写指令 28H(8bit)写指令 0CH(8bit)写指令 01H(8bit)延时 2ms(8bit)写指令 06H(8bit) 在哪里显示写入指令地址LCD1602 内部显示地址由于写入指令或数据的时候数据线D7恒定为高电平即如果想要在0x40显示字符则实际写入的地址为0x40 0x80。显示什么字符写入数据LCD1602 模块字库表由于字符A的ASCII码为65即0100 0001与LCD1602 模块字库表一致因此在写入字符的时候直接传入一个A即可。LCD1602显示一个字符LCD1602与STM32F103C8T6板子接线PB0-RSPB1-RWPB2-ENPA0-D0PA1-D1PA2-D2PA3-D3PA4-D4PA5-D5PA6-D6PA7-D7STM32CubeMX相关配置配置SYS配置RCC配置GPIOmain函数编写/* USER CODE BEGIN Header */

DHT11DHT11介绍DHT11用来实时检测空气中温湿度一次完整的数据为40bit即5个字节DTH11的通讯过程用户发送一次开始信号后,DHT11从低功耗模式转换到高速模式,等待主机开始信号结束后DHT11发送响应信号,送出40bit的数据,并触发一次信号采集, 用户可选择读取部分数据.从模式下,DHT11接收到开始信号触发一次温湿度采集, 如果没有接收到主机发送开始信号,DHT11不会主动进行温湿度采集.采集数据后转换到低速模式。时序图如下 一些宏定义将通讯过程拆分成3个过程配置DTH11输出数据、输出数据0、输出数据1配置DTH11输出数据输出数据0输出数据1DHT11输出0或1主要取决于DHT11一段信号后的高电平持续时间获取空气中温湿度并发送到串口DHT11与STM32板子接线PB7-DATSTM32CubeMX相关配置配置SYS配置RCC配置串口1配置GPIO由于DHT11的DAT接口既需要输入也需要输出因此需要自己在main函数中配置无法使用STM32CubeMX配置main函数编写/* USER CODE BEGIN Header */

4针OLEDIIC协议IIC协议IIC全称Inter-Integrated Circuit (集成电路总线)由PHILIPS公司在80年代开发的两线式串行总线用于连接微控制器及其外围设备。IIC属于半双工同步通信方式。IIC特点简单性和有效性由于接口直接在组件之上因此IIC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。IIC构成 IIC串行总线一般有两根信号线一根是双向的数据线SDA另一根是时钟线SCL。其中时钟信号是由主控器件产生。所有接到IIC总线设备上的串行数据SDA都接到总线的SDA上各设备的时钟线SCL接到总线 的SCL上。对于并联在一条总线上的每个IIC都有唯一的地址。IIC传输数据过程的三种信号起始信号时序图终止信号时序图应答信号发送器每发送一个字节8个bit就在时钟脉冲9期间释放数据线由接收器反馈一个应答信号。 应答信号为低电平时规定为有效应答位ACK简称应答位表示接收器已经成功地接收了该字 节 应答信号为高电平时规定为非应答位NACK一般表示接收器接收该字节没有成功。时序图IIC发送一个字节数据时序图OLED屏OLED写入指令或数据①选择OLED屏写入0x78选择第一个OLED屏写入0x7A选择第二个OLED屏②选择命令还是数据选择命令写入0x00选择数据写入0x40③传入信息将命令或数据传入OLED的寻址模式在OLED上哪里显示字符OLED显示屏是一个128列*64行的点阵垂直方向由8个PAGE控制每个PAGE控制8个点阵。选择PAGE在垂直方向的哪个位置显示向OLED写入指令0xBx即b1011 0xxx例如选择Page 3时写入指令0xB3即b1011 0011。 选择列在水平方向的哪个位置显示向OLED写入指令0x0x和0x1x即b0000 xxxx或b0001 xxxx例如选择第1列时写入指令0x00即b0000 0000和写入指令0x10即b0001 0000。 它由第一条指令的低四位和第二条指令的低三位组成七位来控制水平方向的128个点阵选择第64列时写入指令0x0F即b0000 1111和写入指令0x13即b0001 0011。OLED的三种地址模式页地址模式水平地址模式垂直地址模式选择寻址模式在一个PAGE上写满数据后数据从哪里继续开始 向OLED写入指令0x20后继续写入指令0x0x即b0000 00xx例如选择页寻址时写入指令0x02即b000 0010。 OLED初始化写入一下命令来对4针OLED进行初始化OLED显示一个点OLED与STM32板子接线在STM32F103C8T6的产品手册中找到板子上的I2C1接口PB6作为I2C1的SCLPB7作为I2C1的SDAPB6-SCLPB7-SDASTM32CubeMX相关配置配置SYS配置RCC启动I2C1main函数编写/* USER CODE BEGIN Header */
