Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Is there any way to find out which version of MM+ firmware is running from within the program?

PRINT MM.VER says 5.01 on my board, not 5.1...
Is that normal?

Yes.

From MM Manual p50
  Quote  The version number of the firmware in the form aa.bbcc where aa is themajor version number, bb is the minor version number and cc is the revision
number (normally zero but A = 01, B = 02, etc).

EDIT:
BTW.
Is there already a way to do a (soft-)reset? Something like CPU RESTART but with the startup banner.Edited by twofingers 2016-01-27

No, not that I can think of. But CPU RESTART does the same thing as cycling the power (except for the banner).

@Geoff,

thanks for clarifying this!

There is also no "unofficial code" for this purpose known? Eg something like a unexpected error which leads to a reset.

No, that is trapped on startup and an error message is displayed instead of the banner.

Why is the banner so important?

Only way i can think of is to connect a pin to MCLR and drive it low. It will cost you a pin, but it will certainly work.

Oh,wait. What about WATCHDOG 1?

That's nothing I cannot live with. But I would prefer to see the banner after a reset. Makes the status more clearly - for me!
I'm often using more than one MM (different MMBasic versions) at the same time.

"connect a pin to MCLR and drive it low.": that's a HARDreset. I use that often.

"WATCHDOG 1" gives you
  Quote  Watchdog timeout
Processor restarted


Thanks MB.

Michael

Edit
I would prefer a "verbose mode" for the cpu restart command (CPU RESTART V). Edited by twofingers 2016-01-28
