There are however alternatives to essentially get more functions through use of one Spark.function. @luz used that to create parameters for his MessageTorch. I combined that with some Jquery stuff from one of @bko tutorials to create an LED strip controller. Feel free to take a look at it. Although it’s far from perfect, it gives you an idea as to how these parameters might work. I’ve tried to somewhat comment it, so hopefully it’s somewhat usefull. You can find it here as a .rar file.
Good luck, and let us know if you need any more help. Until then, happy Sparking
For documentations sake: If you’re building locally you could of course edit the amount of Spark.fucntions to be available. This is currently limited to four because each of them takes up some precious memory. Because there are various alternatives you could use, it’s generally not neccesary to increase this number of functions. I just wanted to point out it’s possible if there’s a need for it.
