求翻译：（3） 异步单片机控制。我们这边有做过一些灯箱屏，里面放个单片机，单片机里面有个USB接口。每次把要播放的节目放到自己的U盘里，然后将U盘插入到显示屏的单片机上就可以用了。这种上最简单的控制方式。是什么意思？

(3) asynchronous microcontroller control. Our side has done some light box screen, which is placed on a single chip microcontroller which has a usb interface. Each program you want to play on their own u disk, u disk insert can be used to display microcontroller. This simple control.

(3) asynchronous chip control. Here we have done some light box display, put a single chip, single-chip inside a USB interface. Every time you want to play to the program on to your own U disk, and then U disk into the display on the chip can be used. This is the most simple of ways.

(3) Asynchronous monolithic integrated circuit control.Us has has made some lamp box screen, inside puts a monolithic integrated circuit, inside the monolithic integrated circuit has the USB connection.Each time the program which must broadcast puts to own U plate in, then inserted the U plate

(3) the asynchronous single-chip computer control. Our side has done some light screen, you could put a single chip, microcontroller with USB interface. Each program you want to play on your own USB drive, and then insert the USB flash drive to display on a single chip can be used. This most simple
