Hi. > Why can not this be done with library/inline functions? I consider that use builtins allows to realize universal delay function easier. Also use builtins will allow to the same delay funcianality it ADA language. > Why does delay always have to be constant? If to allow input parameter to be a variable then it will be necessary to perform division in run-time. It to add a unpredictable delay. > How do we document functionality - for example resolution limitations? "The '__builtin_avr_delay_cycles (unsigneg long __n)' perform a delay of minimum __n cycles." > How is this different from IAR? I do not know. Im don't have IAR C installed. Anatoly.
