I've connected some sensors to a few Teensies, and while it works fine, I want to have one additional layer of plausibility checking by introducing a checksum.
What I've got now looks like
23.0 57.6 1024.0 784
on a line-by line basis. What I want is to have a checksum per line
23.0 57.6 1024.0 784 68
where 68 is calculated from the other numbers (or a hex number, string whatever).
Is there a function in the standard Arduino libraries, that does this in a sensible fashion, so that I don't have to roll
something on my own (and probably worse)?
