Hello everyone! Thanks to the authors for Picobasic. It's wonderful! Do you think you can implement this Basic in the Raspberry Pi 4 or 5 as well? It would be extraordinary!!! Thanks in advance, Teo |

Used to be available - search for Picromite. John |

Hi Teo, https://github.com/thwill1000/mmb4l It's from Tom ... https://sockpuppetstudios.com/ For 32-bit Linux Debian/Raspbian 11 "bullseye" running on ARM, e.g. Raspberry Pi Zero, 1, 2 & 3, use the 'armv6l' build. Note that graphics and audio performance on the original Raspberry Pi Zero is very poor, I have not tested on a 1 or 2. Matthias |

MMB4L will run on any Raspberry Pi with current Raspbian: https://www.thebackshed.com/forum/ViewTopic.php?FID=16&TID=17635 Note that this implementation does not include pin I/O control. The Picromite implementation does not run on current Raspbian--the under-the-hood I/O API was changed by the Raspberry Pi folks.

Thanks for the answers! I would like to make an analogue and digital data acquisition system. To use something similar to the GUI from picom, but on a large display. Do you think it's possible? Teo |

| JohnS Guru Joined: 18/11/2011 Location: United KingdomPosts: 4037 |
Maybe one of the STM32 systems. Lots of I/O, fast displays. F4 is great, H7 even more powerful. John |

| Teo1 Newbie Joined: 06/05/2023 Location: RomaniaPosts: 30 |
Is it faster than the Raspberry Pi 5? |
||||
| JohnS Guru Joined: 18/11/2011 Location: United KingdomPosts: 4037 |
Maybe, maybe not. Why do you need speed? For most of the things they're all fast enough. One thing is with the RPi you've got Linux. Good if you want it, bad if not. Also with the RPi you have very little I/O, with poor things the I/O can do, and pretty poor access to it. John |

As there is no OS to get in the way MMBasic is very fast on the H7. From what I have read Peter stopped work on the Picromite as Raspbian kept changing, requiring large changes to MMBasic. And I/O was a problem. |

Oh, and there's cost - the RPi 5 costs much more than anything else with MMBasic. John |

I would like to use something similar to: https://thebyteworks.com Easy Control and Rack Designer but with Rpi not with Windows PC. |

Rack Designer:  If you like the PicoMite graphics, what is there about the Raspberry Pi that you think would make it a better platform? If you want fast, the CMM2 MMBasic platform could provide everything you want. As others have said, the Armmite F4 might well suit your needs. If you want an OS, there is MMB4L, which does run on the Pi. I don't know exactly what the state of GUI-type graphics is on MMB4L, but the release from a week or two was specifically aimed at providing game-type graphics.

The only reason I'd consider the Pi over the CMM2 is the availability of a capacitive touch screen. As part of my dog and pony show, to my customers, I literally take a screwdriver and attack the sensor to demonstrate the resilience  I do have options where I have a serial interface to the touch screen but ideally, I'd like to stick with components that are easily sourced by end-users. |

As Phenix has entered the discussion, you might consider his robust industrial-grade solution--build the interface on android, and use bluetooth to talk to sensors, which might be hosted on PicoMites. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

There are many ways to skin a cat. :) First you have to define the problem, making special notes for each section. e.g. user interfaces don't need speed but they may need to be flexible in programming, Loop controls with feedback from sensors need to be fast but will never do anything else, they may need something like a RS-485 interface though, where commands will be buffered until the processor has time to handle them. Don't attempt to do everything on one board unless it's a full industrial PC - and be prepared to pay the (monetary) price. If your use interface would be ok on a 5in or 7in resistive touch screen then the PicoMite could handle that well, it supports commands for it. You may choose to interface that to other modules, possibly using I2C or SPI or even bluetooth, each carrying out it's own task or set of tasks. The main thing is that there will be a way to do it and speed isn't *always* as important as you may think. If, for example, there is one short sequence that has to operate *extremely* fast then you may be able to do everything on one PicoMite, using a PIO for that one fast bit. A GUI will always be as slow as a human, but commands from it are on interrupts so you don't need to be sitting around waiting for input.

Other than GUI BITMAP (required by @Martin H's Pico-Vaders game) the MMBasic GUI commands are currently unimplemented in MMB4L. I might be persuaded to do it in the future if there is a "real" project but unfortunately I don't have time to implement it "on spec". Of course someone else could do it, probably a "relatively" simple copy & paste from Peter/Geoff's PicoMite code  .Best wishes, Tom MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Implementing GUI controls for MMB4L is non trivial. They are originally designed to work with a touch screen. To make them work on a monitor required modifications MMB4W does this with an unpleasant hack (my standard programming approach) as does CMM2 - both are hardware specific to a greater or lesser extent. One of the other ports has a version that supports both mouse and touch (MMX?). Probably starting with the MMB4W version is the best approach. To implement GUI controls there are changes needed to multiple source files (7 in the PicoMite) |

Maybe interesting for others? Not a project of mine, but know it since several years.. http://www.comvisu.de/descreenshots.htm Sample screenshot:  GUI language may be switched from German to English but manual only available in German language! Available for Windows, Linux and Raspberry Linux.. Communication with microcontroller boards possible via RS232 or TCP/IP.. bfwolf |

Yes, I should probably roll back on that, I assumed that with the graphics primitives in place that would be a substantial amount of the work done, but there is more to it than that. Getting MOUSE input working first would be a more manageable entertainment. And no doubt more in MMB4L because I have started breaking up some of the more monolithic files. In general, and even ignoring GPIO and the fact that MMBasic is a moving target, MMB4L is still significantly far from feature parity with the PicoMite family and that's not a target I can even realistically aiming for. It's a plaything that I'm working on for my own edutainment, if a couple of people get some "real" use out of it or some things might feed back into the mainline then that's great, but only a side-effect.
