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.

For this beta on the uMite, Geoff mentioned in the beginning of this thread...

"This fixes the "corrupt library" bug and a few more (see the file Changes.txt for the details). Again, my bug list is empty except for the Win10 USB issue."

Can I assume that this beta is pretty much bug free at this moment? (28 pin and 44 pin only)

Thanks!

Yep... I think with the next bump, things should be getting settled...

One last thing, Is there a quick way to check if an SDcard is currently inserted without trying to access it..? Maybe a MM.CardIn value.. Not sure... It's not that hard to test it by doing something like tyying to oped a file, then reading the MM.ERRNO var... So, Not a gig deal...

Thanks Geoff for all you work on this fine code..!

@Geoff, thanks for all the incredible progress, it feels like a solid update and a true Release Candidate 1 !

May I suggest a small feature request: at the command prompt, retyping the last command (without the Enter) when the up-arrow is pressed, "a la Linux".

Regards, Positron.

a means of doing this would be to allow greater flexibility in reading from pins that are assigned to 'special functions'. ie, if pin 7 were assigned as the card detect pin, then allow the line:
IF PIN(7) = 1 then PRINT "card in"

this notion could be extended to allow for the likes of:
IF PIN(12) = 0 then PRINT "console input is low"

and to generate a 1000mS break on the console Tx line:
PIN(11) = 0
PAUSE 1000
PIN(11) = 1


geoff: would these be things that are possible and easy to do? not that i have any particular need, but could imagine that it may be useful for someone. and, of course, assuming that when a pin is assigned to a special function, the PIC32 still provides some ability to read and/or manipulate it independent of that function.


cheers,
rob :-)Edited by robert.rozee 2015-10-24

Geoff,

Great job on the continuing development, thanks. I note from the doco that you specify pinouts for the 100 pin 470 - does that mean that a 100 pin 470 is now formally supported?

If the answer is yes, forum members, is anyone out there in the process or have completed a board design for a 100 pin 470 that they are offering for sale fully assembled?

Cheers,
Doug.

matherp has a 100-pin MM+ backpack PCB - see his other thread. It is in active topics.

EDIT: Whoops! Sorry, that board is for the 64-pin chip...... Edited by Grogster 2015-10-24

Humm... I think a 100 pin motor would be a great idea..!

But, maybe this should be on of those "design by forum idea exchange" kinda things... That way what comes off the table will be something that a lot of folks would want to use as a good project starting platform.. Also, thoughts needed on the type of inter-board interface to use and why.. What types of display units to support ect...

Anyway, something to ponder... Maybe get a fresh thread going...

Hi Z,

Was hoping for some guidance from Geoff as to the status of the 100 pinner but do agree on a new thread. Will wait on his response.

Cheers,
Doug.

PS. Geoff, not pushing at all , just looking for an idea on direction/timing. Doug.Edited by panky 2015-10-24

Check out the SnadPic board for about A$30.

If possible, simply making these pins READ ONLY could be a good compromise to begin with.
So at the command prompt (or during a running program), if trying to write to a 'special start-up pin', or trying to assign one to another option, then you will get a 'warning/error' message as you currently do.

But at any time you interrogate a pin it simply returns the current value.

As far as I know the SnadPic board is currently the only one with the 100-pin chip. It is a nice board and I recommend it for experimental use.

@Panky
If you order the SnadPic make sure you specify it is for a Micromite, it needs to be fitted with a 20 Mhz Xtal and no clock xtal.

Thanks Paul - I was thinking of having a go at modifying Peter M's 64 pin board but wanted to know if the pinout for the 100 had stabilised.

Yes, it definitely has. l have no plans for any changes.

I'm seeing more posts on this forum with this type of error since beta 37:
CPU exception #7 (bus error on load or store) at address 0x9D0289CF
Processor restarted

I'm having them too: PIC32MX170F256B with V4.7B37 and COM2 receiving TTL serial signal with following program:
Open "COM2:9600" As #1
B$=""
Do
If Loc(#1) Then
B$ = Input$(1, #1)
Print B$;
EndIf
Loop

Produces this error after 1 or few seconds.
Flashed back to V4.6B, same circuit, same program, does not produce this error and runs OK.

I have run into this problem also, and tried a few different things to try and figure out what is happening. I too am using com2 exactly like you are. I did a CPU 40 and haven't had a problem since. Give that a try and see if that helps and maybe we can narrow this down.

I tried CPU 40 and CPU 30, but in my case this "CPU Exception #7" error remains.
