Hi Luke
The goal is set the device for have the best value mW@GHash (in other words best performance)

For do this I need to measure power and I already do it, but I need also to know hash rate and change number of bit.

In summary I need two function:
1 - receive hash rate
2-  set bit number

I have free pin on MCP2210 and of course free pin on micro

I think you will implement easily this 2 function.

Thanks in advice
