Quote MODSAMPLE won't work in MODFILE's PAUSE mode. There is no way to change this?

Completely impossible

Quote Then at resume, you have a charged AC coupling, that is driven by the new (silent ? around 50%) audio, and the capacitor discharges again, with shown result.

No nothing to do with that - the issue was that the channels were backwards so stop left was tapering from pause right and visa versa. Didn't show when using tone with both frequencies the same

Out of interest:
How do I enter the ~ on the German keyboard? [AltGr]+[+~*] (to the left of the [Enter] key) does not work. In the terminal this is no problem.
[AltGr]+[Q@] for @ works on keyboard. Therefore it is not the [AltGr]-Key.

Peter,
I was interested in how this all works, after poking around,don't really understand it fully but I think this additional line in USBKeyboard.c might be required.
If its confirmed as OK then its missing from all ports.

if((modifier & KEYBOARD_MODIFIER_RIGHTALT) && Option.USBKeyboard==CONFIG_GR){
if(keyCode==0x24)return 0x7B;
else if(keyCode==0x25)return 0x5B; // 91 [
else if(keyCode==0x26)return 0x5D; // 93 ]
else if(keyCode==0x27)return 0x7D; // 125 }
else if(keyCode==0x2D)return 0x5C; // 92 \
else if(keyCode==0x14)return 0x40; // 20 @
else if(keyCode==0x64)return 124; // 100 |
else if(keyCode==0x30)return 126; // 48 ~

HDMI/USB/2350 02RC7
I know SD CARD limitations from manual.
The maximum file/path length is 63 characters.

Still what I am observing.

If from cmd prompt I CHDIR`ed, for example and now sit under directory total lenght of say 27 symbols;
If I cmd FILES now and files are listed, there is for example file with 40 symbol lenght file name ;

Path+file = 67 symbols
If I will cmd KILL it will be deleted no problem.

Now, if from program line, if I would CHDIR same dir and tray chek is there MM.INFO(EXISTS FILE fname$) it will return 0 as now path is 27+40=67 so illegal (while shorter file names would return 1 as should)

This leads to funny errors.
For example in latest JAVAVIs file manager such file (violating path+fname> 64 rule) is reported as 0 bytes (while cmd FILES would report as 74558417) and if tried to copy it would crash system to restart. After restart file name is copied to A: 0 bytes size

I am ok with that, if you say it is limitation

Maybe add checks to avoid hitting the limitations of the file system(s)?

John

Sure. I do checks. I am absolutelly ok with that.
I understand too, program line might not be able to do what command entered at cmd prompt does. Reported just 'in case'.
It can be safely ignored by developers if it is as it is

OPTION FLASH SIZE 16777216
OPTION COLOURCODE ON
OPTION KEYBOARD US
OPTION PICO OFF
OPTION CPUSPEED (KHz) 360000

Hello,

I setup a testing environment with a PGA2350. This runs solid at 360MHz, with the non VGA version overclocking even works up to 378MHz with enabled PSRAM.
It delivers a very sharp picture at 800x600 with perfect colors..very nice!

I tested it all day long and it never crashed while executing programs. These programs run in MODE 3 and heavily use 2 framebuffer and drawing commands like polygon. All fine

But it crashes in 3 of 10 when coming from the screen in MODE 1, then edit a file with no matter content and then exit the editor by pressing F2.
Sometimes it shortly displays "resetting - invalid address", other times just "reset"
but no total hang.
When the editor is left with F1 and then RUN it works.

When switching to MODE 3 and/or switching back to MODE 1 sometimes it draws a white
tile. That sometimes happens as well, when leaving the editor.
I think once it drew a white tile, the editor will crash for sure next time with F2.

FRAMEBUFFER LAYER only works in MODE 1, in Mode 3 it says"Error : Layer Buffer must be in tightly coupled RAM, declare before oth". F, 2 and N work. Correct?

Editor crash only happens, when there is something to save

Correct. Layers cannot be in PSRAM (too slow) and in mode 3 you don't have enough main ram for a layer @ 800x600 = 240,000 bytes

I'll look at whether the tile buffers are overlapping other ram in 800x600 - sounds like that might be the case.

UPDATE

I've checked and that is OK. I need the full sequence of mode/buffer changes that cause the crash and/or spurious white tiles and what font you are using

COLOURCODE ON is enough. Now edit something and leave with F2

If I do that often enough (and add/edit code) it will hapen

IIRC you wrote that you've tested with a faster RAM type. Where you successful?

What is the program doing? Is it immediately switching to mode 3 for example? I can't replicate.

New and:

MODE 3

Circle 200,200,50

Like I wrote, it happens when it tries to save before execution

This example worked at the first time.
Then I removed the blank line and it crashed

edit the code but change nothing in the end is enough, triggering a save is all it takes

Nope - never crashes for me - I'm just about to post RC8 so have a try with that and see if any different.

Ok..will report.

Last finding/impression: it takes much longer than I'm use to until the save process is finished and getting back to the screen/tty console, like 1,8sec for 60byte prog..

V6.00.02RC8 is available on

https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip

Fixes various pops with PWM and SPI audio
Includes tilde support for German keyboard as per Gerry's fix
PLAY PAUSE now available with MOD file playback
LIST VARIABLES [longstring%()] ' optionally save the variable list to a long string
Max program/heap sizes now:

RP2350
VGA, VGAUSB, HDMI, HDMIUSB - 184KB
PICO/PICOUSB - 304KB
WEBMITE - 208KB

RP2040
VGA/VGAUSB - 100KB
PICO/PICOUSB - 128KB
WEBMITE - 88KB

Notes:
Continuously holding down/up arrow in the editor on long files may cause the firmware to lock-up: currently no known solution as it seems to be an sdk/stdio issue. Use page up/down to move through long files.
Third party RP2350B based Webmite is not a supported configuration

My current intention is that functionality will be frozen after 6.00.02 with the only changes after that being bug fixes that seriously impact usability. I think it's about time I moved on to another project

@Peter,

Did some more testing, playing WAV and PLAY STOP.
At roughly 15% of the cases there is a plop/glitch. And when it happens, it is (up to now) always on both channels at the same time.

This is on the last RC8 test version you released for VGA 2040 only. update:Not on the above mass release. Our posts crossed. Is there anything changed in the new RC8 mass release that makes these tests useless ?

The WAV played (Dire Straits live) starts with a low audio amplitude, so that is why it looks as if nothing is played.

Fixed the download - sorry, and just been testing and can't break it irrespective of the direction of the taper - about 50 trials so far

play wav "future":pause rnd*10000:pin(gp0)=0:play stop:pin(gp0)=1

Didn't measure but the time returning to the prompt seems to have increased for some millis. But I tried it a hundred times with no crash so that version is very promising for my (individual??) problem.
Many thanks for your work!

Sorry, have to correct myself.
I switched to RESOLUTION 800 and it happens again.
So this might have to do with overclocking. But for that argument please bare in mind, that I see it _only_ happening in this one case. beside that, I haven't noticed a crash while playing with the system.

During writing found this :

disabling PSRAM seems to "solve" the problem. I leave the above
