Add BitConverter

description

Converting between byte[] and eg. float is a rather common action in embedded development.
This is also acknowledged by functions such as Microsoft.SPOT.Hardware.Utility.ExtractValueFromArray.
This just needs a few more overloads and be a bit more standardized (Eg. the .net BitConverter).

This was added in the 4.3.1 QFE

Woops, how do I change the type from "Issue" to "Feature"?

This is commonly requested. It is on NETMF's road map. See the Documentation page.
GHI added an overload to do float conversion in our library.
Personally, I like the Utility methods more than BitConverter for efficiency reasons. It is very common to convert numbers to byte arrays many times during an application runtime. BitConverter returns a new byte array every time whereas Utility methods can insert into an existing array.

I agree about the efficiency issue. But the ExtractValueFromArray etc. should at least be moved to the standard BitConverter class and namespace. (For consistency.) And you might also consider renaming the functions so they'll match the existing ones.

"It is on NETMF's road map. See the Documentation page."

I can't seem to find it anywhere on the road map. Do you have access to a better version that the one on codeplex?

I see you're assigned to the PWM/Analog issue though. Very nice! I were afraid that GHI would keep to themselves with all the wonderful things you've been creating. PWM is not your best shot though. How about redesigning your RLP to real P/Invokes and then contribute those? ;)

I see BitConverter at the bottom after the PWM by a couple of lines...

Hm, I only see "BitArray" in that area. (System.Collections.BitArray hasn't got anything to do with System.BitConverter. Furthermore I cannot understand why anyone would want to add the BitArray to tinyclr. It doesn't really add anything besides code spam.)

Oops, I read it wrong.

@ Zach, Lorenzo, MSchwarts.

You guys are more then welcome to utilize my BitConverter, which expands upon the ByteReader, ByteWriter done my MSchwartz.

If you want to compile your own solution, the full implementation is available here.
