WIN 7 need to install the WIN7driver驱动程序x.exe

How to flash UF2 file (after install it into the switch)

• solder a magnetic switch between the GND and RES
• turn off the switch
• pull in the type-C, connect the switch with the PC
• Ues the magnet near the magnetic switch (twice at one second, to short the GND &RES)
• normally it will be a new disk in you PC file explorer
• if the PC say unknow usb driver ,just pull down the type-C and pull in it,or try again
• copy the *.uf2 file into the new disk, then the disk will disappear.
• done.

如何升级芯片的固件(装上机器后升级)

• WIN7 需要安装驱动程序,WIN10不需要
• 必须要在芯片GND和RES中间焊接干簧管
• 关闭 switch
• 通过 type-C数据线连接到switch,
• 1秒内用磁铁触碰干簧管两次(实现短路)
• 通常情况下,电脑就会显示出一个U盘,
• 把 *.uf2 文件复制进去 这个U盘,U盘会自动消失,升级成功.
