 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. |

No sorry for not explaining properly OPTION RESOLUTION nn [,cpuspeedinKhz] For 640x480 the display frequency can be set to 60Hz (252Mhz) or 75Hz (315MHz) by appending 'cpuspeedinKHz' to the command (252000 or 315000) More changes: Page 17: Mode 4 with optional layer (significant memory usage) Page 47: The automatic application of a layer buffer is implemented in VGA versions mode 2 and (RP2350 only) mode 3 as well as HDMI modes 2, 3, 4, and 5. Page 111: FRAMEBUFFER LAYER [colour] Creates a layer buffer “L” with a colour space and resolution to match the current display mode. The optional parameter colour is specified as a number 0-15 (modes 2 and 3), RGB888 colour (mode 4) or 0-255 (mode 5) and specifies a colour which is ignored when the layer is applied to the display. In display modes where automatic layer application is not supported a layer buffer acts as another framebuffer. |

Will the optional parameter override OPTION CPUSPEED? Or is the parameter only affecting the PIO frequency, which can be different from CPU frequency? |

The frequency for HDMI is set by the OPTION RESOLUTION command. OPTION CPUSPEED will give "Invalid option" HDMI is nothing to do with PIO Edited 2024-11-30 20:29 by matherp |

Geoff Another tweak of functionality will be in final release OPTION MILLISECONDS ON/OFF (temporary defaults to OFF) This option enables millisecond output in the TIME$ function ie HH:MM:SS.mmm NB: the milliseconds are set to zero whenever the time is updated using the TIME command, WEB NTP command or RTC GETTIME command Edited 2024-11-30 21:20 by matherp |

And another - page 139 VGA AND HDMI displays and framebuffers in modes 2 and 3 and LCD Framebuffers ONLY Sprites are always stored as RGB121 'nibbles' for efficiency |

A great manual Geoff! It's a lot of work, and many thanks... A couple of things: pg66 - OPTION TCP SERVER PORT nn (there's no reference to the optional timeout) "OPTION TCP SERVER PORT nn" is also not listed in the option table starting on pg85 some simple typos: pg6 - You can ignore and files that may be on this “drive” ("and" => "any"?) pg83 - MMINFO(SYSTEM I2C) (MMINFO => MM.INFO) pg137 - SETPIN GP25, DOUT | HEARTBEAT : NOT AVAILABLE ON THE WEBNITE VERSION (WEBNITE => WEBMITE) John |

Geoff, Some time ago Volhout produced a document titled: "Graphics in the PicoMite VGA" with additions by Martin H. Peter was going to ask you to include it with the downloads but that has no happened. See The file is attached. pico_graphics_V3.2.zip Bill Keep safe. Live long and prosper. |

I have not seen it, but it is a great tutorial, so it is defiantly going in. Volhout and Martin - if you have an updated version, please send it on to me. Geoff Geoff Graham - http://geoffg.net |

Hi Geoff, The file Bill send you was the consolidated last version of the document. There have not been updates to it since, but I did a final check against the syntax of 6.00.01 (blit-sprite changes) pico_graphics_V3.3.zip Thanks Bill and Martin for your contributions. Geoff, if you include this please do a careful check on layout. It was editted in Libre-Office. And Libre Office is known to sometimes fail on layout of DOCX documents.

For 2040 WebMite, standard 2040 PicoMite, 2350 VGA and perhaps others it is now "01-01-2024" It would seem either the manual or firmware needs adjusting to one or the other. If backward compatibility is desired maybe standardize on "01-01-2000". Edited 2024-12-01 22:25 by phil99 |

Regarding the very nice graphics demo in the manual starting on page 234. I am using a five-inch SSD1963 LCD Display with this configuration: OPTION SYSTEM SPI GP10,GP11,GP12 OPTION SYSTEM I2C GP8,GP9 OPTION LCDPANEL SSD1963_5, LANDSCAPE OPTION GUI CONTROLS 75 OPTION TOUCH GP18,GP19 GUI CALIBRATE 1, 134, 3777, 2065, -1340 OPTION SDCARD GP22 I had issues until I made the following changes to Example Program: Note: [nn] where nn is the line number Also I found the MsgBox command no longer works in 6.0. See line [83]. I retested it again in PicoMite 5.07 and it works fine [3] mode 10 Error : Unknown command Fix: made it a comment. [4] Option console serial Error : Invalid Option Fix: made it a comment. [16]’CLS Fix: removed comment character [19] GUI cursor on 0, MM.HRes\2,MM.VRes\2 Error : Unknown command Fix: made it a comment. [42] 6 ,90,MM.Info(FontHeight)+12,RGB(yellow),RGB(64,64,64) Error : Invalid character: , Fix: moved it back to line 41 and added minus character before the six “6”. [44] 6 ,90,MM.Info(FontHeight)+12,RGB(yellow),RGB(64,64,64) Error : Invalid character: , Fix: moved it back to line 43 and added minus character before the six “6”. [78] Select Case click(REF) ' find out the control touched Error : REF is not declared Fix: changed click to touch. [83] Error : Invalid character: Fix: Replaced line with mbox=1 (Because MsgBox does not work on 6.0) [110] Select Case click(LASTREF) ' use the last reference Error : LASTREF is not declared Fix: changed click to touch. ============= Once last thought, the Gui calibration gives me an error. So I simply enter this: GUI CALIBRATE 1, 134, 3777, 2065, -1340 However If I use a seven inch board, then the gui calibration works fine. Kevin |

Geoff: that GUI example code is for the CMM2 rather than the Pico. The issue with calibration of the 5" SSD is probably a power issue. The 5" is the hardest version to use because it uses 3.3V power and needs a lot of it - probably too much for the Pico's regulator to be reliable What version are you testing with? Messagebox was fixed in a recent 6.00.01 release candidate |

I'd like to see updates for pico 2/2350 hdmi modes in the manual and the memory limitations . I could dumb it down from what I know about hdmi layers and copying screen but don't know much. Peter has explained a bit but what is needed is a "this is the memory you got", "you can use this much", hdmi modes use "this much" but want it diagrammed what is possible in each mode :) |

matherp, I am using PicoMite MMBasic Version 6.00.00RC1 You are correct I do use the 3.3v power from the Pico. I have a separate plug for five (5) volt power that supplies a seven-inch display, and optionally i can route that to VSYS pin on the Pico. When I do, I can calibrate the five inch display. Good to know. I will look and see if I can find the new RC. Please keep the GUI Example Program; its a nice demo. I hope the comments I gave will help the work on the Draft manual. Kevin |

Page32 Measuring Distance ... for this sensor because it uses 5V levels for its echo output. The Raspberry Pi Pico 2 can tolerate 5V (while powered) so, in this case, level shifting is not required. The last sentence does not apply to the trigger input signal. With a 3.3V voltage trigger signal, an echo signal is sometimes lost. Maybe it depends on the components used. In my opinion, you should recommend the US-100 ultrasonic distance sensor. In this case, no level converter is required.  If you can get a HC-SR04 ultrasonic sensor with CS100 chip inside or an US-025 you need also no level shifter. The quality is better too.  Pictures.zip Gregor Edited 2024-12-02 09:04 by aFox |
