Re^8: Split any number into string of 8-bit hex values (=1 byte)

Note that for 200, C8 is a negative number, so the 00 is required to make it so that C8 00 is positive.

Ah, that might be the reason for that odd trailing '00' in the OP

How does an 8-bit register in an I²C device "know" that an 0xc8 byte started out as 200₁₀ or as -56₁₀? One can make similar arguments about 16- and 32-bit registers. I share the misgivings expressed by LanX here. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]
