sleep walking in SXSim

Posts: 16
hi Sxers
I have written a very simple program 'sleeper' shown below to investigate the SLEEP mode for the SX28 and simulated it with the SXSim.
When I RUN this program, SXSim stops at the SLEEP instruction but wont reset with MIWU input on port rb.
If I WALK or STEP this program, SXSim ignores the SLEEP instruction but jumps to the interrupt routine with MIWU input on port rb.
Is the SXSim working as the SX28 would be during sleep and wake up ?
Are SX program examples or application notes on using the SLEEP command available on this web site?

sorry, for now SXSim does not correctly simulate the SX wake up feature. I have put it on the TODO list, so let me see if I can implement this in the next version.

That explains it, can I also assume that SXSim only sleeps in the RUN mode ?
I will test my SX28 sleeping routines using hardware.
SXSim is a very usefull program, any exhancements would be a bonus.

The current version of SXSim does not actually "sleep" in RUN mode - it simply terminates the Run mode - IOW, you can't wake it up via MIWU pins for now. I think this should be possible though without too much coding.

Terminating the SXSim RUN mode on an SX SLEEP instruction is sufficient for most debuging purposes but full MIWU functionality would be really cool !

Could give us an estimate as to when a new version might be available?
Thanks,
Alex.

Fear not that your project does not work, for it will,
Fear not if you see·a long dark path ahead, but follow it,
Fear not if what worked now refuses to,
For the only thing that's perfect is imperfection.
please understand that I have developed SXSim as Freeware. So I can only work on new versions when I have enough spare time between my regular business. Right now, I'm pretty "overloaded" with "income-generating" work, so it is hard for me to give an estimate when the next version of SXSim will be released. I can only ask you to be patient, and to stay tuned.
