First of all - Here is the thing (Click image for full size):
It is a relatively simple Decibel meter.
So I need to convert the value from the ADC into decibels.
Does anyone have experience in calculating this?
I have never used the standard floating point library - is it buggy?
There is no hurry in doing the calculation so the floating point approach might do the trick.
Any ideas - or experiences ?
