| Jul 18, 2017 at 23:22 | comment | added | Asmyldof | To start, unless you turn that off with directives, your attempt of "if(==255) =0; else ++" will be optimised to just ++ by the compiler, because it's a cleverclogs, so that will indeed make no difference at all. Do these fixed positions happen consistently even if bit has wrapped around. I.e. at 5th byte and 37th byte, etc, or does the location in your 32byte series change after a wrap? Try what happens if you don't sleep the controller. It's been long since I used the x5 series, so can't remember, but there may be issues with some sleep states and missed IRQs in a few "older" Tinies. | |
