I need to find the frequency of a sample, stored (in vb) as an array of byte. Sample is a sine wave, known frequency, so I can check), but the numbers are a bit odd, and my maths-foo is weak. Full range of values 0-255. 99% of numbers are in range 235...

And have that equation applied to telemetry data that is coming from a device connected via a serial port. The incoming data points...
