Server error when generating a colour via a function #1331

Closed el-voss closed 1 year ago

el-voss commented 2 years ago

Hello,

I wanted to program a colour wheel in the roberta lab for an Arduino Uno with an RGB LED. For this I coded a function, that takes a number as an argument and gives back a colour. But when I try to use this function in the loop, I get a "server error". The program is attached below. I tried it with firefox and chromium.

Steps to reproduce:

  1. Import the program below.
  2. Open the code view (will not be opened, but show a server error instead) or press the "play" button.

This is an issue for arduinos, mbot and sensebox. There is also a problem when trying to use the following blocks for arduinos:

The fix needs changes to repo arduino-resources as well, since NEPODefs.h needs a function overload.
