Hi folks.

I downloaded an updated a CMM to version 4.5, now a program that was running fine in 4.4 throws this error when I try to run it:

[24] SetPin D11,9:SetPin D12,2:SetPin D13,2:Port(D2,8)=1
Error: Invalid output pin

I will check the update text file, but I don't immediately see why MMBASIC is upset when this line of code was fine in 4.4.......

EDIT: Tried changing the line so that the output pin is OOUT instead of 9, but got the same error.

Downgraded the firmware to version 4.4, and the error is gone, and the code runs as expected.

Curious....Edited by Grogster 2014-07-26

Smoke makes things work. When the smoke gets out, it stops!

Hi Grogs
separate your code and find out which pin it is. You can then submit a bug report.

It might be related t this problem:

It is the PORT command having problems there but the error looks the same.

This does seem like a bug.

I will add it to the todo list for the next version.

I know that things have moved on quite a bit, and this is revisiting very old ground...

Is there any plan (Geoff?) to issue a V4.5.X of the Maximite firmware that has this PORT bug fixed?
I use V4.4B as I use the PORT command to drive stepper motors (monochrome MM). It does not work with V4.5. But I then miss the nice enhancements that V4.5 contains.

I've searched the forum but cannot find any reference following this post (and the one linked below). If anyone has any updated info, I'd appreciate the help.

Thanks.
Rod.

I'm waiting for this fix for a while too.

I need to use port command to control a SN76489 PSG, but in 4.4b firmware I loose peek and poke commands.

This one must have got lost between the cracks. I have added it to the current bug list but I need to setup the test environment so it may be a little while .

Thank vou very much, Geoffg.

With this fix I can optimize the sound library.

I'm finishing the media editor to CMM and the port, peek and poke commands are very important. With this media editor anyone will can read and create sprites, fonts, screens, maps and musics entirely in CMM hardware, without a PC, like the good old times.

Could you please try this version (V4.5B): 2018-03-03_152807_ColourMM_MMBasic_V4.5b.zip

I'm sorry to use you as an unpaid tester but after all this time it was amazingly difficult setting up the old compiler chain, etc and then both of my Colour Maximites chose this time to develop some sort of mysterious fault which cut short my testing.

I am reasonably sure that I have nailed the bug but I need a third person to verify this.

Thanks
Geoff

Thanks for addressing this Geoff. I did not notice your post until a couple of days ago and hence the delayed reply.

I have loaded version V4.5B onto my Monochrome MM. At the end of the usual process, with the green 'power' LED flashing slowly, power removed and re-applied,
it appears to not boot. No green LED nor any output to screen.

I tried several cycles of loading V4.5B and then V4.4B.
V4.4B loads and boots fine.
V4.5B - as above, not booting.

Thanks,
Rod.

Is the Colour version not different from the Monochrome version?

Thanks WW. Yes, of course. I had forgotten that they were different firmware hex files.

My fault, I thought that only the CMM version was needed. I will generate a monochrome Maximite version and post it tomorrow.

@Geoff

I just tried the above CMM 'test' version (on your original CMM) and it still gives the same error.

Have re-flashed (and re-downloaded) three times now just to be sure I have the intended test firmware you posted.

Can the PORT command use a 'D2' reference (as in Grogster's example)?

Whatever I try, even with:
PORT(x,1)=1
I get an Error : Invalid output pin

OK, please try this: 2018-03-11_121510_Maximite_V4.5C.zip

This contains version V4.5C for both the colour and monochrome Maximites. I have tested it and the PORT command/function works (for me). Note that this is an update so you do need to load it via the bootloader (not a PICkit3).

Anyone who does test it, could you please report back on how it worked for you. Thanks.

This program runs without error on a mono Maximite:

Quote ' mono maximite tester
SETPIN 15,DOUT
SETPIN 16,DOUT
SETPIN 17,DOUT
SETPIN 18,DOUT

FOR n = 1 TO 16
PORT(15,4)=n
PAUSE 20
PRINT n
NEXT n

It's one that failed earlier
