“It is quits hard to use but you need to put in the block show full screen at the end of each command.

“There are two libraries for the display, depending on whether you have a V1 or V2 microbit. Make sure you get the correct version of the library otherwise nothing works. It only works with the online microbit editor. It does not work with mu-edit. It works very well with V1 microbit but there seems to be a problem with the refresh rate for V2 microbit. There is only one font size. If you want a different font size, you have to create the bitmap for it.”
“Note that the interface for this only works on Makecode. There is no interface for the mucode editor and mcropython. You can run makecode in the makecode variant of python. This is quite unfortunate since it means you always have to be connected to the internet to modify the code. There are 2 libraries - for V1 and V2 microbit. If you use the wrong library, you will get error 927. The refresh rate with V1 microbit and library is about 1s. The refresh rate with V2 microbit and PXT library is really slow - 10 to 30s. You have to be very patient if you're using V2 and the PXT library.”
“As a previous reviewer said, it takes a while to get your head around this. Rendering is slow - about 40s to draw 3 rectangles, so after downloading, be prepared to wait before anything appears. The colours are 6 bit. I have a Microbit V1 and V2 - make sure you get the right library otherwise nothing happens. Currently, the python interface only works with makecode, which requires an internet connection. I haven't found out how to get it to work with mucode yet.”
