What this article shares with you is about how the makecode extension that supports scrolling display in four directions and adjusting speed is like. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Without saying much, let's take a look at it with the editor.

As we all know, when displaying text, makecode only supports scrolling from right to left, but does not support scrolling in other directions, and the scrolling speed can not be adjusted (graphically). The function is relatively simple, which is not convenient in many cases.

MicroPython/micro:bit Chinese Community has developed a new extension package, ScrollText, which can enhance the function of displaying text. It supports scrolling display in four directions, and the scrolling speed can be adjusted arbitrarily, making the text display more convenient.

The use of the ScrollText package is very simple, as long as you enter the warehouse address of ScrollText (see below) when makecode adds an extension, you can find it and add it to makecode after searching.

After you add an extension, you can set the display text, display direction, and delay time. The display text is arbitrary text (English, numbers, symbols, etc.); the direction supports up and down four directions; the display speed is controlled by delay time, and the smaller the number of delay time is, the faster the scrolling display is.

Here is a simple demo program:

The above is how the makecode extension supports four directions of scrolling display and adjusting speed. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article.
