The error is correct. You have set GP1 as the I2S BCLK and then in the library are trying to use it for something else.

@Peter,

Last post I added 2 ZIP's. The one that uses PIO ASSEMBLE 1,"mnemonics" (the classical one) assembles now correct.
But with your new PicoMite.uf2 the new code throws an error. There is something wrong with .side_set

RUN
0: A02B
1: 20A0
2: 0043
3: 00C2
4: A0C9
5: 8000
0 0 5
[161] _side_set 1 '1 side set bit
Error : Unknown command

Looks like a similar translation issue.

Regards,

Volhout

PicoMiteRP2040V6.00.02b6.zip

This now works for the old version
On the new version replace ".side_set" with ".side set" to be consistent with other directives and the official syntax. Also you have spurious "" on a .line command. After these changes it works.

Download from Geoff's site also updated with all RP2040 versions

Hi Peter,

Why does this:

? Mm.Version

Print the trailing zero on this:

6.000204 0

Running on "PicoMiteVGA MMBasic USB RP2040 Edition v6.00.02b4" .

Best wishes,

And again,

Should

Mode 2

clear the display if already in Mode 2 ?
It doesn't, but I think it should, however I've been wrong before

I'm in 2 minds about this one. First it did and now it doesn't. But it could again - who knows?

Ah ... the parser (and my memory) was obviously slacking.

I think there are existing programs (PETSCII Robots for one) that assume it will clear the display, but it's not a massive deal.

The problem is that if the mode command actions when the mode is the same it will close framebuffers, reset colour maps, clear tiles (mode 1), etc.. This can be a pain during development so I made the decision that a mode change to the same mode is a NOP.

I can see your problem and I don't know whether it should clear the data-structures or not; I can make an argument either way since sometimes you want all that stuff clearing without having to do it piecemeal. Perhaps less controversial could it just act as a CLS rather than a NOP and leave the data structures intact ?

Too complex. Does it also clear a layer buffer or leave that showing? I think it has to be all or nothing

Tom,

In robots603 I already added the CLS. It was especially confusing since in PETSCII we do a new RUN, clearing everything, but now except framebuffers since the MODE 2 does not do it anymore. I would have expected RUN to clear everything.

It is also confusing if you run multiple of javavi's VGA demo's, Most of them run in mode 2. So if you stop one, and run a new one, there is leftovers from the previous.

My personal opinion in this is not important, but I understood the previous implementation better. Now you are forced to adapt your code to clear everything manual.

That would have met the principle of least surprise.

Volhout said ... but I understood the previous implementation better. Now you are forced to adapt your code to clear everything manual.

On balance I agree. I certainly implemented an equivalent to the previous behaviour in MMB4L and I *think* that is how the CMM2 behaved.

Tom

My own i2c scanner works fine and no errors on an RP2350 with HDMI and USB and Audio I2S.
A possibility may be that there is still something in the memory that has not been properly erased due to a leak.
Or do I have to manually clear the memory with a .uf2 file (should be in the update list for RP2040 and RP2350) or option reset and enter it manually?
Tested on other boards without Audio I2S, it works fine so far.
Does anyone have any other ideas?

Jan

I have found a bug, I think:

MODE 3 16 colours with a resolution of 640 x 480 (RP2350 only)

does not work, just a black screen on ALL my monitors and TVs. If I am typing (blind) "MODE 1" and ENTER, the screen suddenly appears again (in mode 1).. But MODE 3 isn't working.

Hi Amnesie,

Does your board use a DS1307? Not a DS3132 ? Looks like it has a crystal.
PS2 keyboard AND PS2 mouse ?
Schematics ?

@Peter,

The beta6 from Geoff's site compiles and runs PIO.
Both classic style, and new style (after changing labels to .label, and .side_set in .side set).
And of coarse removing the """ I forgot.

Also nice that the built in editor colors the nmemonics correctly. No coloring for the .directives yet, but the mnemonics is already very nice.

Hi,

no it is not a DS1307 it is a PCF8563. There is one thing I hate: Cheap counterfeit China Modules. You can get the (in all ways superior) DS3231 cheap, but try to get the genuine for under 10€ (mouser 12€).

The PCF8563 in contrast costs 75 cents here in Germany (from NXP). For better accuracy I left 2 optional capacitors for tuning, if needed.

Yes my board has PS/2 keyboard AND PS/2 mouse. On the bottom layer of the PCB there is an audio power amplifier, too.

And I didn't used a schottky diode for reverse polarity protection but a p-ch-mosfet.

Sorry I've got no schematics, I did it for myself, but if there is interest I will do a schematic.

Daniel
