MM.VER=6.0201 on Pi Pico 2 W, when I try to define any one of 4 Buttons I require using GUI BUTTON #1, "EXIT", 0, 280, 90, 30, RGB(RED) I get GUI reference number #NN is in use. I have defined 80 in memory but it seems whatever number I try I get the ERROR.

Help needed please

G'day OA47,
Can you let us know which flavour of V6.02.01 you are using?
You mention a Pico2W, are you using the WebMite firmware?

Regards, Lyle.

OA47,
No worries, can you also let us know your option list, just in case it is display specific?

Just tried:

> list
'prog to test gui controls

Option default integer

GUI button #1,"1",10,10,100,20,RGB(red)
GUI button #2,"2",10,30,100,20,RGB(green)
GUI button #3,"3",10,50,100,20,RGB(yellow)
GUI button #4,"4",10,70,100,20,RGB(blue)

End
>

And it ran ok but I don't have a physical display connected so cannot see the output.

> option list
WebMite MMBasic RP2350A Edition V6.02.01
OPTION SYSTEM SPI GP18,GP19,GP16
OPTION FLASH SIZE 4194304
OPTION COLOURCODE ON
OPTION CPUSPEED (KHz) 200000
OPTION LCDPANEL ILI9488, RLANDSCAPE,GP14,GP13,GP12,GP20
OPTION GUI CONTROLS 32
>

Also tried option lcdpanel virtual_C but that is causing other problems:

> option lcdpanel virtual_C
> edit
PC=>

Might also be worth updating to a later firmware, is there a reason for sticking with V6.02.01?

Regards, Lyle.

As you have OPTION LCDPANEL ILI9488 try OPTION LCDPANEL DISABLE then:
> option lcdpanel virtual_C

You can then save the image.

I don't have a Pico 2 W but "GUI button #1,"1",10,10,100,20,RGB(red)" works with the virtual LCD on the non-W versions.

G'day OA47,
Found a Silicon Chip Pico Backpack with almost the same option list, now with Pico2W fitted.

> option list
WebMite MMBasic RP2350A Edition V6.02.01
OPTION SYSTEM SPI GP18,GP19,GP16
OPTION SYSTEM I2C GP26,GP27
OPTION FLASH SIZE 4194304
OPTION COLOURCODE ON
OPTION CPUSPEED (KHz) 200000
OPTION LCDPANEL ILI9488, RLANDSCAPE,GP14,GP13,GP12,GP20
OPTION GUI CONTROLS 80
OPTION TOUCH GP15,GP17
GUI CALIBRATE 0, 210, 156, 1284, 845
OPTION SDCARD GP21
OPTION AUDIO GP2,GP3', ON PWM CHANNEL 1
>

And this short program to test gui buttons:

> list
'prog to test gui controls

GUI button #1,"ONE",10,10,100,20,RGB(red),RGB(green)
GUI button #2,"TWO",10,30,100,20,RGB(green),RGB(red)
GUI button #3,"THREE",10,50,100,20,RGB(yellow),RGB(blue)
GUI button #4,"FOUR",10,70,100,20,RGB(blue),RGB(yellow)

Do
For i = 1 To 4
CtrlVal(i)=1
Pause 1000
CtrlVal(i)=0
Next
Loop While Inkey$=""

End
>

And all working ok. A couple of suggestions:

Try OPTION AUTORUN OFF and without the WIFI network
Reload the firmware with a CLEAR FLASH RP2350 or CLEAR FLASH UNIVERSAL first.
Is it possible there is a different GUI CONTROL with the same #reference number? they all have to be unique.

Hopefully something works.

Regards, Lyle.

Lyle, I have stripped out all other GUI references and turned off the WIFI but still no go. I will reflash the Pico, reload and test again.

OA47

I have cleared the Pico and loaded 6.03 but I still have the same error. Can someone please point me to CLEAR FLASH RP2350 file?

OA47,
All 3 versions in ZIP file below, sometimes CLEAR_FLASH_RP2350 works and sometimes CLEAR_FLASH_UNIVERSAL, it may depend on the version of the Pico.

Clear_Flash_ALL.zip

The fact V6.03.?? is giving problems is very strange, however the problem with LCDPANEL VIRTUAL_C seems to be present up to V7 so maybe this is a similar.

Can I also suggest after loading the updated firmware starting with the minimum options, just OPTION SYSTEM SPI, OPTION GUI CONTROLS 10 and OPTION LCDPANEL to see if it works, the program above might be a good first test.

Regards, Lyle.

Lyle, I can run your code with all options loaded, but when I load my code the error returns. I am very confused.

OA47
Confusion averted. I found that GUI code was accessed more than once that explains everything.

Thank you for your help in the diagnosis.

Thanks from me too.

I hadn’t seen this collection before. But generally, this one has always helped me so far:
