SIOC and Encoders (ROTATE function, etc)

[aVaTar]

Righto, so ROTATE, LIMIT etc functions do the "magic" bit. That's fine just as long as I know what happens.
Thanks for clearing that up man!

nope,
if you do not want that then you have to condition the encoder value to be +1 if >=0 and -1 if <= -1.

Yep that's exactly what I ended up doing yesterday, just following my nose and looking at what actually happens.

Glad you got it "sorted". SIOC is powerful, but sometimes challenging, particularly the principle that the code attached to a variable is only executed when the variable changes value - caught me out many times

Yep me too... I was going nuts with the way it defied "standard practices" and that there was no clear documentation as to what exactly happens. Or I might have missed it when fiddling about yesterday.

Must admit that code attached to variables is very natural to me. They are called event handlers in JavaScript or a Window Procedure in Windows API. Then there're processor interrupts that function in a similar way with interrupt handler only executed when hw requests it(say encoder changes value ) Anyway that's off topic.

Thanks a lot guys, I appreciate your help!
PS. MCP is now coming along nicely

Hi guys,
SIOC's statement:

v2 = ROTATE 0 359 L0

has indeed the behaviour that Peter described; the ROTATE function takes the actual value of v2 before incrementing/decrementing, 'range wraparounding' and finally 'assigning'.

In C/C++ one would write:

v2 = Rotate(0, 359, L0, v2);

Indeed. SIOC is an 'event driven scripting language', not a normal procedural programming language.
