 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. |

Swap swaps a hidden sprite for a showing one. It is not a two way thing This version will be the release. The only change will be to force an option reset when loading the first time It never occurred that anyone would use a 128 pixel display as a console  Various people have reported getting into a mess try to edit when there are very few characters on a line but I'll perhaps relax this now we have continuation characters Edited 2025-05-09 19:56 by matherp |

It is really possible with font 8 and is enough for editing on the go. The main reason is that there is not a single display out there, which can be read in direct sunlight, which is a must for my application. With those displays (yellow/green version) reading in direct sunlight is no problem. Greetings Daniel |

When it does finally come out of RC I don't suppose you can be persuaded to find another hobby for 6 months whilst we poor users write some software to use all the latest and greatest without the sands shifting any further ;-) Best wishes, Tom MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

There is one bit of functionality to go in after this release which is the text based graphics support. It is pretty much completely stand-alone though. |

Peter, Maybe you missed my message a bit back on page 39 at the top? I have only been able to test LIST PINS on an HDMI screen because I have not been able to test VGA yet. Tera Term works fine. Thanks. Greetings, Jan. |

Understood. Result I am observed at first was merge, not swap. Print @(0,0) "a" Sprite read 1,0,0,8,12 Print "spr a" Sprite show 1,50,50,1 Pause 1000 Sprite hide 1 Print @(0,0) "b" Sprite read 2,0,0,8,12 Print "spr b" Sprite show 2,80,50,1 Pause 1000 Sprite hide 2 Pause 1000 Print "Swap a <> b" Sprite show 1,50,50,1 Sprite SWAP 1,2 End  This made me confuse and I dived into old forum records. It seems manual is somehow incomplete/unclear, as optional [,orientation] is not explained Sprite SWAP 1,2,4 <-- makes it swap correctly 0,1,2,3 MERGE (!) 2 to 1 with orientation  Another observation was - after Sprite SWAP 1,2 I can SPRITE HIDE 2 which is not displayed but I can not SPRITE HIDE 1 which is displayed.

Peter, Thanks for the response. Unfortunately it is not different but I appreciate the amount of work and time you have put into this project. Greetings, Jan. |

Do you mean ANSI for the console screen? One question and no answer is ok. Is it thinkable you extend the family with a hdmi graphic server? My idea would be to use the existing ssd routines for the clients. Do you see any solution to extend the ram of a 2350? Edited 2025-05-11 09:19 by dddns |

What is an "hdmi graphic server"? PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

The "normal" RAM on the RP2350 cannot be extended because it's on an internal bus that isn't available externally. The only expansion possible is via the QSPI system (i.e. like the flash but using PSRAM). Consequently it will always be much slower than the internal RAM.

After sleeping a night over my stupid questions I would like to reduce it to: Would GPIOs be fast enough and possible to interface some fast ram? |
||||
| Mixtel90 Guru Joined: 05/10/2019 Location: United KingdomPosts: 7817 |
GPIO is way too slow. The internal bus has the CPU "sockets" and the RAM on it, together with the peripherals. One of the peripherals handles QSPI, which is used for the flash. A second chip select can be brought out for the PSRAM, which is also on the QSPI. You can't get to the internal bus at all so the operational RAM can never be extended. The HSTX opens up the possibility of Write-Only memory. :) You *can* hang memory off the GPIO pins, I'd suggest SPI flash or RAM, but it's generally tiny and dreadfully slow. It makes PSRAM look lightning fast. If you want external fast RAM then the RPxxxx family is the wrong way to go. Look at the CMM2, which does have extendable RAM.

Thanks Mixtel! I precise my question: is it possible to feed the screen buffer with ram attached to GPIOs |

If you are talking about HDMI or VGA then the answer is categorically NO Edited 2025-05-11 21:21 by matherp |

Hi Peter, Can you please tell me the default values for (USB) keyboard repeatstart and repeatrate? Thanks! Michael causality ≠ correlation ≠ coincidence |

Try putting all above SUB MM.STARTUP in MM.STARTUP. Perhaps that will help. I think items in the library only get read when called so they need to be in a Sub of some sort. SUB MM.STARTUP WEB NTP -4,"time.nist.gov" CONST TRUE=-1 CONST FALSE=0 OPTION ESCAPE OPTION BASE 1 DRIVE "B:" PRINT DateTime$(now) END SUB SUB MM.END PRINT "END PROGRAM" END SUB Edited 2025-05-12 15:02 by phil99 |
