 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I think I've fixed this so please download again. It seems to have been a compiler bug ignoring a "volatile" specifier on a variable. All I've done is re-ordered some code and the problem has gone away. This code hasn't changed for ages so it is concerning that you were seeing those symptoms |

Unfortunately, behaves the same. Its should show still as b5 (`WebMite MMBasic Version 5.09.00b5`), right? I downloaded it from Geoff's site unter beta versions. I reloaded the page. Best Thomas |

Hmmm. Standard PicoMite is definitely fixed but not the WebMite. This is really disappointing because there is no code bug. What happens is that the startup waits for the first of 5 seconds or the USB console connecting. The problem is that the 5 seconds counter which is incremented in an interrupt routine isn't being seen as counting so the wait loop never ends |

I connected a 5V usb power pack to picovga with usb 00b5 and heartbeat flashed and the auto run on code started. In teraterm you Have to select serial then com 1,2 or the last which will be picomite then win beeps. You must set baud to 115200. mmcc the console in mmedit finds the pico when connected and baud is 115200. |

This seems to work - thanks!! I'll do further testing and report back, if there is another problem. |

Some minor new version in the build chain? |

Thank you. It now works properly for the PicoMite version 5.09.00b5. The LED now immediately starts flashing after 5V voltage and after reset and immediately beeps twice that a USB driver has seen the RP2040, but only 5 seconds later the com port is released via Tera Term. The operation is otherwise normal. No errors seen yet. The comment about the com port number from stanleyella is, in my opinion, for a USB connection determined by the USB port in the RP2040 or the separate USB to TTL converter, each of which has its own unique com port number and is visible at Tera Term Setup Serial port and eventually also select this when using MMEdit(4).

Small addition. The 5 second wait time is now gone. Good work Peter. Jan. |

Hi Peter, I've been testing B5, this is on a GameMite, with a ILI9481IPS screen, which I know is physically too large, but I wanted to try 480x320. I have enabled LCD Console. When I edit a program and scroll to the bottom of the screen, using the arrow keys, when the screen tries to scroll, I get 'Error : Display not configured' and the Pico locks up, requiring a reset, if I use the page up/down there is not a problem. PicoMite MMBasic Version 5.09.00b5 OPTION SYSTEM SPI GP6,GP3,GP4 OPTION SYSTEM I2C GP26,GP27 OPTION COLOURCODE ON OPTION HEARTBEAT OFF OPTION CPUSPEED 252000 'KHz OPTION LCDPANEL CONSOLE OPTION DISPLAY 26, 60 OPTION LCDPANEL ILI9481IPS, LANDSCAPE,GP2,GP1,GP0 OPTION TOUCH GP5,GP7 OPTION SDCARD GP22 OPTION AUDIO GP20,GP21', ON PWM CHANNEL 2 OPTION PLATFORM Game*Mite I got the same on B2, so I thought I'd try B5. Any ideas? Thanks. Regards, Kevin. Edited 2024-03-06 05:20 by Bleep |

You can't read from a ILI9481IPS display - or at least I couldn't get it to work, so console mode should be disabled for this display. I'll fix this in the next beta Edited 2024-03-06 05:59 by matherp |

Hi Peter, Ok, I didn't realise that the console function required reading to work. However I may have another problem with that display? When I run this program, It's a Matrix code rain type display, when I do the Blit, to move the frame buffer down by 4 pixies I start to get random artifacts all across the screen? I'm now assuming this is the same problem? But if I try to do 'Blit Framebuffer F,F....' that is not allowed? so will the only way to resolve this for this display be to set up 2 framebuffers F & L, and ping pong between the 2, which will get quite messy? ' Matrix code rain ' turn off default typing and force explicit typing Option EXPLICIT Option DEFAULT NONE SetPin GP25, DOUT Dim Integer horiz=MM.HRes/10-1, vert=MM.VRes/10-1 ' Set up the rotation strings Dim String orientate(3) Length 3 =("CMN","CMD","CMU","CMI") Dim Integer shade(horiz),i,k=&hA00,l=2,LCD=0,c,r,x,n,m,y Font 7 If MM.Device$="PicoMite" Or MM.Device$="PicoMiteUSB" Then FRAMEBUFFER create FRAMEBUFFER Write f LCD=1 Else MODE 2 EndIf CLS ' Draw 'Matrix' code rain display Do If l=0 Then ' Move the 'code' down one line, gradually decreasing Green ' If white change to Green If shade(m)=&hF0FFFF Then shade(m)=&hff00+k:shade(n)=&h ' Reduce Green brightness For y=0To horiz:shade(y)=Choice(shade(y)<&h1000,0,shade EndIf ' Move whole screen down 4 pixies ' Blit Framebuffer f,f,0,0,0,4,MM.HRes,MM.VRes-4 Blit 0,0,0,4,MM.HRes,MM.VRes-4 ' Blank out the top 4 lines of pixies Line 0,0,MM.HRes,0,4,0 Inc l If l>1 Then l=0 ' Output to display m=Rnd*horiz:n=Rnd*horiz ' Set to white initially shade(m)=&hF0FFFF : shade(n)=&hF0FFFF ' Draw the top line of randomised characters, rotating rand For x=0To horiz Text x*10+4,4,Chr$(Rnd*75+48),orientate(Rnd*3),,,shade Next EndIf If LCD Then ' FRAMEBUFFER Wait FRAMEBUFFER copy f,n,b ' Pause 40 Else Pause 80 EndIf Print Timer:Timer =0 Loop End Thanks for looking.

Hi Peter, Understood, but I'm trying to untangle something here, because if on a VGA I create a frame buffer, with 'Frame Buffer create' & 'Framebuffer write F' and then use Blit, that operates fine on the framebuffer & when I then do 'FRAMEBUFFER copy f,n' the shifted framebuffer appears on the VGA screen correctly. However if I do exactly the same on this LCD I get garbage, I don't believe this is using the read from 'LCD' framebuffer, but maybe it is? I realise this is a rubbish LCD, but I don't currently have another 480x320 LCD to test with. I have tested with a 320x240 LCD and that works as expected. If this screen is no good, maybe it would be better to remove it completely to save memory? Sorry the code I pasted before got mangled & I can't now correct it, this should be correct and is doing the same with FRAMEBUFFER in both LCD and VGA.

I probably never implemented framebuffer copy for this display so it is using some incorrect driver. I'll remove it in the next beta. |

Version 5.09.00b6 https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip Fixes bug in MATH M_MULT Blocks ILI9481IPS display from being used as the console Major internal re-engineering of command tokens Programs in memory will be corrupt and must be re-loaded from disk or re-downloaded FOR KEVIN There is a bug in BLIT of a framebuffer when a 480x320 SPI display is the main display. I don't believe that there is a bug for an ILI9341 display or VGA. Please confirm. Edited 2024-03-07 04:59 by matherp |

@matherp Hi Peter; Is it possible to have the PicoMiteVGA of 5.09.00xx version also allow for the OPTION VGA PINS reassignment without the USB coding? Love all the new stuff BTW!  Thanks for all your efforts,  Hans ...  |
