可以考虑将部分重复的代码提取出来，封装成函数，减少重复代码的出现。此外，可以使用更加直观的变量名，增加代码的可读性。代码示例：

void display_net_info(int netid, int index, int row) {
    char buf[20];
    float val = gRunPara.COMMS_NetInfo[netid][index].val;
    
    // display name
    memset(buf, 0, sizeof(buf));
    sprintf(buf, "%s", gRunPara.COMMS_NetInfo[netid][index].szName);
    LCD_DisString((index%9)+1, row, buf);
    
    // display value
    if ((index >= COM_NET_PCL && index <= COM_NET_DIR) || (index >= COM_NET_YXM && index <= COM_NET_SNTP) || index == COM_NET_SYNCTM) {
        if (index == COM_NET_PCL) {
            LCD_DisString((index%9)+1, row+16, (char *)gcszLcdComPcl[(int)val]);
        } else if ((index > COM_NET_PCL && index < COM_NET_DIR) || index == COM_NET_SNTP) {
            unsigned char bytesforIP[4];
            if (index == COM_NET_IP) {
                (float)bytesforIP = val;
                sprintf(buf,"%d%d%d.%d%d%d.%d%d%d.%d%d%d",bytesforIP[0]/100,bytesforIP[0]%100/10,bytesforIP[0]%10,bytesforIP[1]/100,bytesforIP[1]%100/10,bytesforIP[1]%10, bytesforIP[2]/100,bytesforIP[2]%100/10,bytesforIP[2]%10,bytesforIP[3]/100,bytesforIP[3]%100/10,bytesforIP[3]%10);

                    LCD_DisString((index%9)+1, row+10, buf);
                }

        } else if (index == COM_NET_AREA) {
            LCD_DisString((index%9)+1, row+16, (char *)gcszLcdSynctmMode[(int)val]);

        }
    } else {

在调用 `display_net_info` 函数时，可以直接传入对应的参数，简化代码，提高可读性。
