 | | Multitasker test script —Ralph Hempel
|
| | | John, You might want to try this little script to try out the tasker. It's based on Koh's demo. If you type TASK0 AWAKE and then .TASKS, you will see the chain is ok and that TASK0 is running. Now press the RUN button on the RCX and try .TASKS (...) (26 years ago, 12-May-99, to lugnet.robotics.rcx.pbforth)

I have not posted it on my website because it is very early beta software. Cheers, Ralph Hempel - P.Eng ---...--- Check out (...) (26 years ago, 12-May-99, to lugnet.robotics.rcx.pbforth)

| | | | My DEFCON code multitasks OK (except when it tries to STOP). I doesn't actually work yet because it needs SendMessage (or non-blocking EMIT) but I'll post it here if anyone is interested (actually I'll post it unless anyone objects). (26 years ago, 12-May-99, to lugnet.robotics.rcx.pbforth)

| | | | Here it is, it is working, but is waiting for IR_MODE_HI, STOP and a non-blocking EMIT. There is a light sensor on the centre connector pad. .dp displays proximity in the LCD as DEFCON.RawLight alternating with the average ambient raw light sensor (...)

| | | | | John, I tried to put this part of the code into my test script without the ping word and it worked fine. Yes, I uncommented the line that does not work for you. I'm going to have a closer look at ping...I wonder if it's running out of stack or doing (...) (26 years ago, 13-May-99, to lugnet.robotics.rcx.pbforth)

|
| | | | John, I've been looking at your ping routine and note the following... Even if FF EMIT did not block, the wait makes things irrelevant. At 2400 baud, the FF is out the port within 4 msec. In fact, if EMIT did not block, you could probably wait jsut (...) (26 years ago, 13-May-99, to lugnet.robotics.rcx.pbforth)
