Maybe the result interests somebody. "BitSequence-0.03" compares three versions. 1. BitSequenceSimple: without timers 2. BitSequenceTimer: using the so-called "Interpreter-Timer-Interrupts" 3. BitSequenceAsm: jumps into an assembler-call To give the so-called "Timer-Interrupts" a real chance, I tested it with a 500µs interval. The winner is of course the "BitSequenceAsm-version". For my astonishment, the "BitSequenceSimple-version" is more stable than the "BitSequenceTimer-version". That also shows the limits of the so-called "Interpreter-Interrupts". In addition the "BitSequenceTimer-version", works first no more correctly, if we reduce the interval time. Finally I come to the opinion, only the "BitSequenceAsm-version" is suitable for implementation of a asynchronous serial communication protocol.
