R / C receiver ouput from c ++ to flowcode

[Monie Jacobsen]

Is there anyone here who will be assisting with the following

In Arduino used "map" procodure.
How to make "map" procodure in Flowcode 7 ??
Can you give a code eksemple?

Code:
Channel 2 = map (Channel 2, 970, 1970, 0, 255); // Change input about two 0-255 Bytes

Signal from receiver 970-1970

Hi Monie,

Can you just do something like this.

Code: Select all

FloatVar = Number (970 to 1970)
FloatVar = FloatVar - 970.0
FloatVar = FloatVar / 3.90626
NewNumber = FloatVar

NewNumber should now be in the range 0 - 255.

Or if you don't want to use floating point maths then you could use this to get an approximation 0 - 250.

Code: Select all

IntVar = Number (970 to 1970)
IntVar = IntVar - 970
IntVar = IntVar / 4
NewNumber = IntVar

You may need to do additional bounds checking on Number to ensure you are in range.

e.g.

Code: Select all

if ( (Number >= 970) && (Number <= 1970) )
Yes : Code from above...
No: NewNumber = 0

Hi Benj
Many, many thanks for the info.
