 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. |

Fully appreciate it -- "if you don't ask you don't get"  Radians / Degrees Conscious of the saying "A horse designed by committee will look like a camel" ---- would it be possible to set the unit of measurement of angles (either degrees or radians) -- from an education perspective, radians are only covered in post-16 maths, so using radians can be confusing for younger users. Could this be an OPTION ANGLE ?? Nim Edited 2020-09-04 21:18 by Nimue Entropy is not what it used to be |

Is ReDim an option to expand / contract arrays once declared? Entropy is not what it used to be |

People have already mentioned a mouse with firmware-level interrupt support for reading the X-Y location. I would be great to have something like this; the Nunchuk, IMHO, is a very poor substitute. I would love to have a line continuation character so that we could have longer lines in MMBasic. This should not require any big changes in the language; most languages that support line continuations just use a tiny preprocessor that simply glues the multiple lines together into a single long string before feeding it to the parser. -Bill |

Which bit of what I wrote was unclear? The CMM2 functionality is essentially complete other than tweaks. Mouse support and continuation lines are not tweaks |

Remember you can request the source and add the things you want. John |

In fact, I have the source, but doing it just for me does not make a lot of sense. If the change is useful, it should be available for everyone. -Bill |

If it's a lot of work, and Peter is too busy or disinclined to do it but someone else does it, then it can be adopted and thus available as you say. John |

Continuation lines won't work and would break major parts of the MMBasic internals - don't bother trying. Mouse support via USB is do-able but would be either/or with a keyboard. Mouse support via PS2 is also do-able but would need an I/F adapter and uses a defunct standard. It could be done in a CFunction but can't easily be added to the firmware as there are no command of function slots free Edited 2020-09-07 02:24 by matherp |

PS2 mouse is easy with an Arduino nano to convert PS2 to Nunchuk or serial. I have a working unit which does both. I will probably post the details later this week. There are USB mouse to serial adapters around but I have not tried them. USB mouse to Nunchuk should be doable But I have plenty of PS2 mice to keep me going for many years. Using Nunchuk or serial interface makes interfacing to programs easy in Basic. Jim VK7JH MMedit  MMBasic Help |

Jim, how are you encoding your mouse data to nunchuk format? I've been tinkering with something similar. My 'chukulator' emulates a nunchuk as far as the CMM2 is aware. A standard PC joystick (15 pin game port) appears as a nunchuk joy stick and buttons Z and C. I'm thinking of putting the mouse data into the 3 accelerometer channels. Ax for x, Ay for y and Az for the wheel. And set the highest bit when the corresponding button is pressed. Visit Vegipete's *Mite Library for cool programs. |

Would it be possible to have a way to programatically load fonts? Perhaps the LOAD FONT command could also accept an array containing the font data? Or better, because then more than one such loaded font would be possible: DefineFont #N where the array is dimmed as integer.fontdataarray() End DefineFont This would be useful for a program like FontTweak running directly on the CMM2, but would also allow programs to alter a font on the fly.

Mouse XY mapped to Wii classic both left and right joysticks. I did both because I didn't know which was the preferred side. I am doing a separate one for joysticks. Sticking with the classic for this one also. The serial is sent out at the same time as the Wii is polled ~ 16mS If there is no Wii polling, the serial is sent every 30mS The serial is easier for the other Maximite devices to handle.

You can LOAD FONT as often as you like, replacing font 8 on-the-fly. Alternatively, you can use up to font 16 within the program. Put them in an include to save cluttering up the main program. Jim VK7JH MMedit  MMBasic Help |

If you are using serial i/o and have (ed) problems with a usb keyboard, this mod might be of interest. It is Geoff's terminal altered to use a usb keyboard. Edited 2020-09-08 11:25 by zeitfest |
