## 7：单片机串口接收气象数据 ### 7.1：串口数据处理 为了能够接收云雀气象仪的数据，我们实用串口通讯来实现数据处理，单片机采用STM32单片机,使用PA9和PA10的串口功能实现。首先初始化串口引脚功能，具体实现方式如下： ```C void Bsp_USART1_Init(unsigned intbound) { //GPIO端口设置 GPIO_InitTypeDef GPIO_InitStructure; USART_InitTypeDef USART_InitStructure; NVIC_InitTypeDef NVIC_InitStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1 | RCC_APB2Periph_GPIOA, ENABLE); //使能USART1，GPIOA时钟 //USART1_TX GPIOA.9 GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9; //PA.9 GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; //复用推挽输出 GPIO_Init(GPIOA, &GPIO_InitStructure);//初始化GPIOA.9 //USART1_RX GPIOA.10初始化 GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;//PA10 GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;//浮空输入 GPIO_Init(GPIOA, &GPIO_InitStructure);//初始化GPIOA.10 //Usart1 NVIC 配置 NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn; NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3 ; //抢占优先级3 NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3; //子优先级3 NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; //IRQ通道使能 NVIC_Init(&NVIC_InitStructure); //根据指定的参数初始化VIC寄存器 //USART 初始化设置 USART_InitStructure.USART_BaudRate = bound;//串口波特率 USART_InitStructure.USART_WordLength = USART_WordLength_8b;//字长为8位数据格式 USART_InitStructure.USART_StopBits = USART_StopBits_1;//一个停止位 USART_InitStructure.USART_Parity = USART_Parity_No;//无奇偶校验位 USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;//无硬件数据流控制 USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx; //收发模式 USART_Init(USART1, &USART_InitStructure); //初始化串口1 /* CPU的小缺陷：串口配置好，如果直接Send，则第1个字节发送不出去，如下语句解决第1个字节无法正确发送出去的问题 */ /* 清发送完成标志，Transmission Complete flag */ USART_ClearFlag(USART2, USART_FLAG_TC); USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);//开启串口接受中断 USART_Cmd(USART1, ENABLE); //使能串口1 } ``` 接着配置串口中断接收数据处理，我这里实用普通的串口中断，当然也可以实用串口空闲中断接收： ``` void USART1_IRQHandler(void) { unsigned char dat; /*使用串口中断接收，不是串口空闲中断*/ if(USART_GetITStatus(USART1, USART_IT_RXNE) != RESET) { dat = USART_ReceiveData(USART1); CBUF_Push(RxBuffer1, dat); USART_ClearITPendingBit(USART1, USART_IT_RXNE); } } ``` 再者，串口定时发送获取气象数据命令来获取气象数据，这里有温度，湿度，风向，风速，海拔，气压等6个参数。 ```C /*获取天气数据状态机*/ voidGet_Weather_Info_StateMachine(void) { // staticunsigned char timeCount=0; // timeCount++; // if(timeCount==20) // { // timeCount =0; // } /*状态切换*/ state++; switch(state) { case STATE_TEMP: USART1_DMA_Send(get_temp_cmd,sizeof(get_temp_cmd)); // state = STATE_HUMI; break; case STATE_HUMI: USART1_DMA_Send(get_humi_cmd,sizeof(get_humi_cmd)); break; case STATE_WINDSPEED: USART1_DMA_Send(get_windSpeed_cmd,sizeof(get_windSpeed_cmd)); break; case STATE_WINDDIR: USART1_DMA_Send(get_windDir_cmd,sizeof(get_windDir_cmd)); break; case STATE_ALTITUDE: USART1_DMA_Send(get_altitude_cmd,sizeof(get_altitude_cmd)); break; case STATE_PRESSURE: USART1_DMA_Send(get_pressure_cmd,sizeof(get_pressure_cmd)); break; default : break; } } ``` 最后，进行数据解析，将保存好的数据放入到指定字符串下。 ``` voidUSART1_IRQ_VerityFun(void) { unsigned char strLen=0; unsigned char i=0; if(flagFrame) //帧接收完成标志，即接收到一帧新数据 { flagFrame=0; //帧接收完成标志清零 strLen = CBUF_Len(RxBuffer1); if(strLen>ResDataPackageLen) { RTT_LOG("len=%d",strLen); for(i=0;i<strLen;i++) { RTT_LOG("%c",RxBuffer1.m_entry[i]); } switch(state) { case STATE_TEMP: memcpy(tempBuf, (u8*)&RxBuffer1.m_entry[ResDataPackageLen], strLen-ResDataPackageLen); RTT_LOG("%s",tempBuf); break; case STATE_HUMI: memcpy(humiBuf, (u8*)&RxBuffer1.m_entry[ResDataPackageLen], strLen-ResDataPackageLen); RTT_LOG("%s",humiBuf); break; case STATE_WINDSPEED: memcpy(windSpeedBuf, (u8*)&RxBuffer1.m_entry[ResDataPackageLen], strLen-ResDataPackageLen); RTT_LOG("%s",windSpeedBuf); break; case STATE_WINDDIR: memcpy(windDirBuf, (u8*)&RxBuffer1.m_entry[ResDataPackageLen], strLen-ResDataPackageLen); RTT_LOG("%s",windDirBuf); break; case STATE_ALTITUDE: memcpy(altitudeBuf, (u8*)&RxBuffer1.m_entry[ResDataPackageLen], strLen-ResDataPackageLen); RTT_LOG("%s",altitudeBuf); break; case STATE_PRESSURE: RTT_LOG("------"); memcpy(pressureBuf, (u8*)&RxBuffer1.m_entry[ResDataPackageLen], strLen-ResDataPackageLen); RTT_LOG("%s",pressureBuf); state = STATE_IDLE; break; default : break; } USART1_Clear(); } else if(strLen<=ResDataPackageLen) { USART1_Clear(); } else { } } } ``` ### 7.2：LCD显示驱动 数据显示，我采用1.77寸LCD显示气象数据。 1.77寸TFT LCD液晶显示屏采用高透光率玻璃基板，配以低功耗驱动IC电路设计而成。其外观尺寸为17英寸×11英寸×2.44厘米（长×宽×厚），重量约为0.45千克。  （1）该款LCD液晶屏采用了高透光率的玻璃基板，使屏幕画面清晰明亮、层次分明、色彩丰富艳丽；同时由于采用了低功耗驱动IC电路设计而成，使得整机耗电量大大降低，从而降低了用户的使用成本。 首先编写LCD驱动显示函数：具体代码如下： ```c #include "main.h" #include "Lcd_Driver.h" #include "LCD_Config.h" //#include "delay.h" #include "stdlib.h"//函数调用头文件 #include "stdio.h" //为了解除sprintf警告 #include "LCD_calculate.h" //#include "global.h" //液晶IO初始化配置 void LCD_GPIO_Init(void) { GPIO_InitTypeDef GPIO_InitStructure;

GPIO_Init(GPIOB, &GPIO_InitStructure); GPIO_InitStructure.GPIO_Pin =GPIO_Pin_15; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;//开漏输出 GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_Init(GPIOA, &GPIO_InitStructure); } //向SPI总线传输一个8位数据 voidSPI_WriteData(unsigned char Data) { unsigned char i=0; for(i=8;i>0;i--) { if(Data&0x80) LCD_SDA_SET; //输出数据 else LCD_SDA_CLR; LCD_SCL_CLR; LCD_SCL_SET; Data<<=1; } } //向液晶屏写一个8位指令 void Lcd_WriteIndex(unsigned char Index) { //SPI 写命令时序开始 LCD_CS_CLR;

Gui_DrawFont_GBK16(40,144,BLUE,WHITE, (char*)pressureBuf); } ``` 将此函数放入到循环任务里面显示，定时3秒刷新一次数据即可。  具体视频为： [各类传感器学习笔记05(LCD显示云雀气象仪传感器数据)_哔哩哔哩_bilibili](
