Marvell自己实现驱动系列文章分为几篇介绍:
每篇更新打开专栏可以看到:
功能如下:
①串口配置区,默认是921600的波特率
②Wi-Fi功能开启区
③STA功能调试区
④AP功能调试区
⑤PING功能调试区
⑥TCP功能调试区
⑦UDP功能调试区
⑧云服务器调试区
⑨Debug日志区
跟PING有关的界面如下:
①要PING的IP地址
②开始PING
③停止PING
④清空PING结果
⑤显示PING结果
目前上位机跟开发板是通过串口来通信,通信格式是json,如果你没听过json,那么自行百度,跟WIFI PING相关的json格式分别如下:
上位机用的c# winform,用的json库using Newtonsoft.Json,此库需要Newtonsoft.Json.dll库
发送代码如下:
private void json_construction_send(string func, string operate, string param1, string param2, string param3, string param4, string param5, string param6)
{
json_commmand cmd = new json_commmand();
cmd.FUNC = func;
cmd.OPERATE = operate;
cmd.PARAM1 = param1;
cmd.PARAM2 = param2;
cmd.PARAM3 = param3;
cmd.PARAM4 = param4;
cmd.PARAM5 = param5;
cmd.PARAM6 = param6;
string json_cmd = JsonConvert.SerializeObject(cmd);
#if CONSOLE_DEBUG
Console.WriteLine(json_cmd);
#endif
if (serialPort1.IsOpen)
{
serialPort1.WriteLine(json_cmd);
}
}
其中跟wifi ping相关的operate为:
string operate_wifi_start_ping = "WIFI_PING";
string operate_wifi_stop_ping = "WIFI_STOP_PING";
uint8_t uart_receive_parse(uint8_t *shell_string)
{

uint8_t* para3 = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"PARAM3"))->valuestring;
uint8_t* para4 = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"PARAM4"))->valuestring;
