WIFI6
Wi-Fi6无线网卡横评，killer 1650 vs Intel AX210 vs Intel AX200
不只有ax200，Wi-Fi6网卡大盘点
wifi6对应802.11ax，可同时支持2.4G/5G。
Intel AX210 vs Intel AX200，AX210采用M.2 2230或M.2 1216形态设计，除了支持Wi-Fi 6E，还支持蓝牙5.2，2x2天线，无线速度最高3000Mbps。高级特性方面，首先就是Wi-Fi 6E独有的6GHz频段，虽然穿墙不佳，但近距离传输速度更快。当然要想用上，外围设备也得支持才行，否则就是传统Wi-Fi 6的2.4GHz和5GHz。
速度
开启5G，VHT80，WPEQ-257 QCA988X不支持VHT160，使用手机iperf3测速，测试手机红米K30 Pro，骁龙865 SOC，接收速度57MB/s，发送速度30MB/s，

Direct firmware load for rtlwifi/rtl8188eufw.bin failed with error -2
驱动编译进内核，但是固件放到根文件系统里，所以加载驱动的时候文件系统并没有加载，导致找不到固件，想了一天，想通了，老哥我想通了。

迅为iTOP-4412精英版之烧写内核移植后的镜像_exynos 4412 刷机-程序员宅基地
文章浏览阅读640次。基于芯片日益增长的问题，所以内核开发者们引入了新的方法，就是在内核中只保留函数，而数据则不包含，由用户（应用程序员）自己把数据按照规定的格式编写，并放在约定的地方，为了不占用过多的内存，还要求数据以根精简的方式编写。boot启动时，传参给内核，告诉内核设备树文件和kernel的位置，内核启动时根据地址去找到设备树文件，再利用专用的编译器去反编译dtb文件，将dtb还原成数据结构，以供驱动的函数去调用。firmware是三星的一个固件的设备信息，因为找不到固件，所以内核启动不成功。_exynos 4412 刷机

文章浏览阅读119次。顺序读写指的是按照文件中数据的顺序进行读取或写入。对于文本文件，可以使用fgets、fputs、fscanf、fprintf等函数进行顺序读写。在C语言中，对文件的操作通常涉及文件的打开、读写以及关闭。文件的打开使用fopen函数，而关闭则使用fclose函数。在C语言中，可以使用fread和fwrite函数进行二进制读写。 Biaoge 于2024-03-09 23:51发布 阅读量：7 ️文章类型：【 C语言程序设计 】在C语言中，用于打开文件的函数是____，用于关闭文件的函数是____。
