3D Body 4 libraries
There are three libraries, doing similar thing with variations: 1. A 3D cube, with or without dice numbers on, can roll by touch or by command or provide a throw result by click. 2. A 3D library for any body, provided that you know how to define its verteces and polygons. There are examples of several bodies which may help, see photos. 3. A 3D library for any body (like 2 above), using Open_GL 1 library (thanks to Agraham). Note that I have very limited knowledge on the use of Open_GL and this implementation is very basic, however the user of this 3D library does not need any knowhow of Open_gl at all. In all libraries you can create a view which is a base panel and the body on it. The panel may be transparent or with a bitmap.

Bluetooth TSPL Printer Class
In the past few weeks, I have been testing a self-adhesive label printer. I have found a lot of information on the Internet, only ESC / POS related information. There is no such TSPL print source code. Later, I asked the printing supplier to go to the tspl instruction file. After constant experiments, I sorted out the following code, hoping to provide reference for friends in need!
