Hello folks,

even if this forum seems dead, I'll try to see if I can get some help.

I have a PID for parking sensors that needs this formula: ((256*A)+B)/100.

when sensors does not sense obstacles the pid returns FFFF, so once the the equation is applied is shown 655,35 meters.

Doing some test I seen that the sensors start to sense obstacles far more or less 2 meters.

That I want to do is to use LOOKUP function in way that wheen the pid returns FFFF, instead to show 655,35 it show a text, and when the value is different to FFFF it shows the value.

I think that is possible using LOOKUP, but I dont understand how to create the equation.

please help 😀
