<![CDATA[REMOTE+ Slider for motors]]>I like the REMOTE+ - feature. Works fine, but... The slider range starts at 0 and ends with 100. Most motors are controlled in the range of -127 to +127. Has anyone an idea of how to manage this?

def slider_Motor_callback(slider_value):
motion.set_motor_speed(2, map_value(slider_value, 0, 100, -127, 127))

without any translation. Works fine with Remote+

with this definition the motors shows absolutely no movement.

def translate(slider_value, inMin, inMax, outMin, outMax):
  return (slider_value - inMin) * (outMax - outMin) / (inMax - inMin) + outMin

def slider_Motor_callback(slider_value):
  motion = Motion()
  motion.set_motor_speed(1, translate(slider_value, 0, 100, -127, 127) )

Seems that mapping or translating might not work in combination with REMOTE. Thanks for your help!

translate(slider_value, inMin, inMax, outMin, outMax)

...
def slider_Motor_callback(slider_value):
global inMin, inMax, outMin, outMax, tof_0
motion = Motion()
inMin = 0
inMax = 100
outMin = -127
outMax = 127
def translate(slider_value, inMin, inMax, outMin, outMax):
return (slider_value - inMin) * (outMax - outMin) / (inMax - inMin) + outMin
motion.set_motor_speed(1, slider_value)
...

But this doesn't work. What might be wrong?

But I cannot see any similarity with the maps-function of other IDE's. Great would be a mathematical function like this from MakeCode:
"map 'speed' from low '0' high '100' to low '-127' high '127'" (or vice versa)
Using arrays is very compicated, too much for me.
