hello.
I'm needing to send a float number from pc to the arduino.
I needed to process this data liake a setpoint.
Does anyone have any idea how I do it?
I tried a lot but whit out any results.
Thanks.
How have you tried? Are you sending it in binary or as ASCII text?
What is the range of the floats you are sending ?
max & min value ?
Nr of digits? / precision?
do they fit in the Arduino float?
Arduino is IEEE754 32 bit float format.
And maybe most important, do you really need (to send) float? If it can be done in integer only it will be much faster & smaller.
