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 OA47 |

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. Edited 2026-11-07 16:51 by mozzie |

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? Edited 2026-11-08 10:54 by OA47 |

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. Edited 2026-11-08 12:37 by mozzie |

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. OA47 Edited 2026-11-08 13:26 by OA47 |

Back again with another GUI programming issue, I have read Geoffs Advanced graphics pdf many times but I still cant get the brain cells to align. I have defined 4 GUI BUTTONS, the first is displayed on the first screen and when TOUCHED provides the second screen which then displays the other 3 GUI BUTTONS. The 3 GUI BUTTONS react to touch (altering the graphics) but do not launch the interrupt. I have played with GUI PAGE, Disabling and ENABLING the GUI BUTTONS but nothing seems to work. The buttons on the second screen work if I display the second screen first. What am I missing? OA47 |

Have you got GUI SETUP in the main loop? It should only be used during the initialisation when initially defining the controls. From then on GUI PAGE in the main loop is enough switch to those predefined pages. F4 H7FotSF4xGT |

OA47 This program cbe-43f-470live.bas.zip, the display section of a Caravan Battery Monitor system makes extensive use of GUI elements in a multi page menuing system. It is fairly well commented and was designed to run on a PIC32MX470 with a 7" LCD touch screen. I think it shows the GUI system well and may be of use to you. Happy to answer any questions on it. Doug. ... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it! |

Gerry, that was the original problem I had when I stated this post, the GUI SETUP was accessed a second time and gave me the error. I have the GUI SETUP before the MAIN LOOP with the other declarations so I do not get the original error. I have even tried defining the GUI BUTTON at the start of a SUB that draws a new screen and DELETING it at the end of the SUB but that did not work. Panky, I have had a quick look thru your code but you haven't been able to use GUI BUTTON in that version of MMBasic OA47 |

How are you calling the sub that switches to the second page. If its called from the interrupt of the touch on the first page you need to ensure that the code finishes/returns to that interrupt and lets it complete, otherwise you will never see any other interrupt. The safest way is to set a flag in the first interrupt and then action that flag in the main loop to show the second page. I am not sure what would happen if you hide the first page in its own interrupt, but probably should be avoided.i.e. GUI PAGE #2 would hide Page #1. F4 H7FotSF4xGT |

G'day OA47, What version of WebMite did you end up using? the GUI commands have had a few additions and changes in later editions to my knowledge. These two programs should run on WebMite V6.02.01 onward: 'prog to test gui controls GUI Interrupt TouchDown Font 1,2 GUI setup 1 GUI button #1,"ONE",0,0,100,50,RGB(red),RGB(green) GUI setup 2 GUI button #2,"TWO",0,0,100,50,RGB(green),RGB(red) GUI button #3,"THREE",0,50,100,50,RGB(yellow),RGB(blue) GUI button #4,"FOUR",0,100,100,50,RGB(blue),RGB(yellow) GUI Page 1 Do Pause 100 Loop While Inkey$="" End Sub TouchDown Select Case Touch(ref) Case 1:GUI page 2:Text 0,190,"BUTTON 1 PRESSED" Case 2:GUI page 1:Text 0,190,"BUTTON 2 PRESSED" Case 3:Text 0,190,"BUTTON 3 PRESSED" Case 4:Text 0,190,"BUTTON 4 PRESSED" End Select End Sub 'prog to test gui controls GUI Interrupt TouchDown Font 1,2 GUI setup 1 GUI button #10,"PAGE",0,0,100,50,RGB(yellow),RGB(red) GUI Caption #11,"Page 1",100,0,,RGB(red) GUI setup 2 GUI button #1,"ONE",0,50,100,50,RGB(red),RGB(green) GUI button #2,"TWO",0,100,100,50,RGB(green),RGB(red) GUI button #3,"THREE",0,150,100,50,RGB(yellow),RGB(blue) GUI button #4,"FOUR",0,200,100,50,RGB(blue),RGB(yellow) GUI Page 1 GPage=1 CtrlVal(11)="PAGE 1" Do Pause 100 Loop While Inkey$="" End Sub TouchDown Select Case Touch(ref) Case 10 If GPage=1 Then GPage=2 GUI page 1,2 CtrlVal(11)="PAGE 2" Else Gpage=1 GUI page 1 CtrlVal(11)="PAGE 1" EndIf Case 1:CtrlVal(11)="BUTTON 1 PRESSED" Case 2:CtrlVal(11)="BUTTON 2 PRESSED" Case 3:CtrlVal(11)="BUTTON 3 PRESSED" Case 4:CtrlVal(11)="BUTTON 4 PRESSED" End Select End Sub Slightly different ways of doing a similar thing. I too took a fair while to get my head around the way the GUI system works, little programs like this are littered through my system while I got my head around it. You also shouldn't use TEXT with the GUI commands but I like to live dangerously at times  Hope this helps. Regards, Lyle. |
