使用WIFI模拟器软件实现Proteus与NetAssist进行TCP通信功能在同一台电脑上下位机为Proteus仿真stm32f103单片机作为服务端上位机使用NetAssist作为客户端使用WIFI模拟器软件与Proteus通过VSPD虚拟串口以JSON格式数据进行通信上位机发送{“LED”:0}、{“LED”:1}控制下位机LED灯亮灭。1.创建Stmcubeide工程配置USART1、USART2均为115200BPS分别连接串口调试软件和WIFI模拟器软件配置PB5口为输出连接LED灯。2.编写程序依赖库cJSON库下载地址cJSON GitHub https://github.com/DaveGamble/cJSON如果解析错误可换json库。/* USER CODE END Header *//* Includes ------------------------------------------------------------------*/#includemain.h#includeusart.h#includegpio.h/* Private includes ----------------------------------------------------------*//* USER CODE BEGIN Includes */#includestring.h#includecJSON.h#includestdio.h#ifdef__GNUC__#definePUTCHAR_PROTOTYPEint__io_putchar(intch)#else#definePUTCHAR_PROTOTYPEintfputc(intch,FILE*f)#endifPUTCHAR_PROTOTYPE{HAL_UART_Transmit(huart1,(uint8_t*)ch,1,0xFFFF);returnch;}intfputc(intch,FILE*f){HAL_UART_Transmit(huart1,(uint8_t*)ch,1,0xffff);returnch;}intfgetc(FILE*f){uint8_tch0;HAL_UART_Receive(huart1,ch,1,0xffff);returnch;}uint8_tmy_re_buf2;uint8_tmy_re_buf[2000];uint16_tpt_w20;uint16_tpt0;uint8_taRxBuffer;//接收中断缓冲/*1.模块Station模式下做tcp server ATCWMODE w 开启AP模式 ATCWSAP”y”,”1234567890”,3,0 设置名、密码、加密方式 ATCIPMUX1 开多连接模式 ATCIPSERVER1,8888创建服务器 ATCIFSR 查看本地IP地址 */charCAT[]AT\r\n;charCRST[]ATRST\r\n;charCMODE[]ATCWMODE2\r\n;charCWIFI[]ATCWSAP\MUC\,\\,3,0\r\n;//加密模式 0 -
