    Sparks,
    The sequence is not that strange. If you observe a specific digit, for example 0,
    you will notice that there are ten ticks between·0's. The pace is slow enough
    to count. This 10 is the supplied interval time in taskInterval array.
    The same applies to the other digits (eg. tasks).

    regards peter

    Anyone using the multitasking programs, I have discovered a bug in the SX/B compiler that affects these programs.

    Where Peter has aliased the array element bits:

    kMisrRunning var kFlag.6
    kMisrFinished var kFlag.7

    These aliases don't work properly. Actually both get aliased to just kFlag.

    The fix is to do this:

    kMisrRunningBit CON 6
    kMisrFinishedBit CON 7

    Then in the program replace "kMisrRunning" with "kFlag.kMisrRunningBit"
    and replace "kMisrFinished" with "kFlag.kMisrFinishedBit"

    Bean.

    Hi Bean,

    Thanks for that info.
    I was just debugging the programs using larger delays in the tasks.
    The tasks then appear to get stuck (eg. only 1 task keeps running).
    I adapted the programs with your suggestion and they seem to run ok now.
    I will upload the modified programs shortly.

    regards peter

    Here is the sx28 version.
    Don't forget to set pinTX to the I/O port you want to use.
