Hi, sorry to bother you but trying gui area on ili9488 and errors. The ili9488 touch is calibrated and the touch test works. I get this error message using gui area 1,2,395,64,14 [17] GUI area 1,2,395,64,14'left button x y w h Error : No memory allocated for GUI controls I spent time reading the latest non vga manual but can't see allocating gui memory.

Open the manual. Use the find function to look for text "GUI". Keep Stepping down the file until you find the answer - took me about 10 seconds Page 51 |

You're asking about a pixel, so using a FUNCTION, whose return value you want. It would be wise, and may well be mandatory, to use some parentheses. More thinking, less bashing out code :) John Edited 2023-03-17 05:32 by JohnS |

option gui controls 4 in teraterm seems to have sorted gui controls but says maximum is 3 not 4, so set option gui controls 10. pixel (x,y) >0 worked. getting there. Now computer opponent... done it before |

Hi, I was interested to see how/whether Picomite's "GUI AREA" coped with a co-ordinate off-screen in Stanleyella's:- gui area 1,2,395,,64,14 Admittedly I have a Waveshare ILI9488W screen - 480 x 320 pixels, not stanleyella's exact model, but with :- > option gui controls 1 > gui area 1,2,395,64,14 Error : 1 is invalid (valid is 1 to 0) and :- > option gui controls 2 > gui area 1,2,395,64,14 Error : 395 is invalid (valid is 0 to 320) Error messaging seems a bit unhappy with the single control ! With best regards, Paul. p.s. I have PicoMite MMBasic Version 5.07.07b27 Nothing so constant as change. |

Hi Pual. the same error , it was a typo. touch seems to like fingernails more than finger prints, touch supposed to be NOT like a phone touch screen. my first try on ili9488. maybe ili9341 better, will try triangle 2,312,66,305,66,319,rgb(yellow),rgb(blue) gui area 1,1,295,64,16 triangle 192,312,130,305,130,319,rgb(yellow),rgb(blue) gui area 2,128,295,64,16 triangle 471,2,479,66,464,66,rgb(yellow),rgb(blue) gui area 3,464,2,16,64 triangle 471,192,479,130,464,130,rgb(yellow),rgb(blue) gui area 4,464,130,16,64 |

Touch on all the LCD displays supported by MMBasic is resistive, not capacitive. That's why you find it works better with fingernals than a finger. The bast way to use these displays is with a stylus (they are often supplied with one). When you want to test an area of the screen it's better to test for the X and Y edges of that rather than for a point. The GUI commands take this into account.

Looks fun... Because I can't help compressing code: ' computer move if cdx% then ' moving in x direction if pixel(cx%+cdx%) then ' move blocked cdx% = 0 cdy% = -1 + 2 * (py% > cy%) ' turn toward player endif else ' moving in y direction if pixel(cy%+cdy%) then ' move blocked cdy% = 0 cdx% = -1 + 2 * (px% > cx%) ' turn toward player endif endif cx%=cx%+cdx%:cy%=cy%+cdy% if pixel(cx%,cy%) > 0 then end ' computer can't move! pixel cx%,cy%,rgb(cyan) Visit Vegipete's *Mite Library for cool programs. |

working on another algo I thought pixel needed x,y "if pixel(cx%+cdx%) then ' move blocked" ? pixel plotting page 111 pixel reading page 135 |

| vegipete Guru Joined: 29/01/2013 Location: CanadaPosts: 1110 |
You are right. I was sloppy. Should be: if pixel(cx%+cdx%,cy%) then ' move blocked andif pixel(cx%,cy%+cdy%) then ' move blocked Visit Vegipete's *Mite Library for cool programs. |

As the amount of RAM used for GUI CONTROLS is rounded up to 2048 bytes anyway there's no point in specifying such low numbers. One control will require 2048 bytes as will 39 controls (39*52=2028 bytes). 40 controls will require 4096 bytes of RAM.

@paceman That's the error I got. I thought the gui controls started at zero but don't. Mick- thanks for clearing that up. It's in the manual but option gui controls isn't really mentioned and the number of gui controls could be better explained imho. pixel page 111 and 135,why not same page? This is my first touch test and seems I'm not the only one who found it not as easy as it looks. I didn't want to ask the forum but I was getting errors I couldn't resolve. I can see why mechanical buttons are used and has anyone tried using resistors and buttons and one a-d input pin? Each button giving a different voltage when pressed. cheers, stan.

In most cases I've had no problems with the Gui controls. They can get a bit awkward if you start to try to do odd things, but most of the time I've found them to be very good indeed. You do need to have a good play to get the most out of them. Above all, remember that when you use them everything is controlled by the user, not by your program. You mustn't go doing things that the user hasn't requested or you can get into an awful knot.

Hi Mick. I noticed cls after gui area disables them, probably says so somewhere. As you can't re dim or define gui area only once, I stuck it all at the start so I could restart the game in code and found moving cls after gui area disabled it. How to restart the game and use cls? dim px%,py%,pdx%,pdy% dim cx%,cy%,cdx%,cdy% dim ts%,tr% cls 'works here gui area 1,1,295,64,16 'left button gui area 2,128,295,64,16 'right button gui area 3,464,2,16,64 'up button gui area 4,464,130,16,64 'down button 'start 'cls 'disables gui area here |

Do you need to CLS? Can you use GUI HIDE to hide all GUI controls and GUI SHOW to bring them back? You can also use GUI REDRAW if the screen has become corrupted. Then GUI SETUP n can set up controls on page n and you can swap them any time with GUI PAGE n. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
