 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. |

Hi Peter, do you think it would be possible to add the "DEL" key to the manual (Appendix F)? Key code: 127, 0x7F. Best regards Michael |

Will do NB: the first post has a typo PrintScreen is &H9D and Break is &H9E. I'll put these into the manual as well Edited 2020-09-07 21:45 by matherp |

Just upgraded to the latest beta. The flashing process was straightforward (pre assembled CMM2) - about the only "issue" is that the flashing software requires JAVA runtime -- and many schools have JAVA disabled (but that's another issue). The actual process was smooth and simple - so much so that I will be able to get techy savvy teachers to do it. Thank you for a clearly written manual. As an aside -- it's a shame that the .bin can't be dropped onto the SD card and flashed from there -- but again, that's not a CMM2 comment. The inclusion of: OPTION ANGLE mode is a real boon to education circles as I can now use this for KS1/2 (up to 11yo) without explaining radians. @matherp -- a heartfelt thankyou, personally and on behalf of the community. Diolch. Nim Edited 2020-09-07 22:31 by Nimue Entropy is not what it used to be |

Can we still "suggest" features....... you knew you'd regret it. My students are finding it extremely difficult to visualise 0,0 being the top left of the screen. For them, 0,0 is the bottom left and the cordinate system behaves like a piece of graph paper. Would it be possible to sneak another OPTION ORIGIN TL or BL (for Top Left / Bottom Left). That way, they can just convert from paper diagrams without any more math... I can program in the aspect ration to get true squares and circles -- they get that as the screen is 800,600 so the pixels aren't square --> just the origin is totally flummoxing them.

No - massive change. Pixels will be square if the monitor is set to display 4:3 image properly Edited 2020-09-08 00:13 by matherp |

OMG!!! I'm an idiot.. We've been viewing the CMM2 via a windowed HDMI capture card on Windows. Viewed full screen and the (as you said) the 4:3 ratio works out square. Sometimes the obvious needs pointing out.   Entropy is not what it used to be |

Maybe just write a small function which translates the y to be the way students expect. (It's trivial isn't it...) John |

Will do -- or in the best tradition of teachers everywhere -- this is now an exercise to the class to write a function to do exactly that. Cheers for the input on this and mucho kudos for all the work. Nim Entropy is not what it used to be |

Since it is for education I've found a way to reverse the coordinates OPTION Y_AXIS UP OPTION Y_AXIS DOWN - default This command can only be used in a program and will revert on exit It is tested with Basic graphics and text and simple BLIT but probably won't work with sprites without more work and other areas may also have bugs Give it a go and let me know Please find attached V5.05.06b4 http://geoffg.net/Downloads/Maximite/CMM2_Beta.zip |

For kicks and giggles, I stuck "OPTION Y_AXIS UP" at the start of a few existing programs. Simple things seemed fine. Obvious things like peeking the frame buffer don't work without recalculating the location. Blit requires that the source image be flipped vertically. In mode 1 (800x600) "blit 0,0,0,0,800,599,1,2" works as expected "blit 0,0,0,0,800,600,1,2" locks the CMM2 and requires a reset Visit Vegipete's *Mite Library for cool programs. |

Someone noticed an issue with Gauntlet, and I found there seems to be a bug in the firmware that ends the program without displaying an error, if OPTION RAM is set (in 5.05.05). Can someone check if it's a problem in the latest beta? Test case at the end. First on the command line OPTION RAM then the program print "about to test, press enter to start" input asd$ Mode 7,16 page write 8 cls 'it doesn't reach here. page write 0 print "finished test" input asd$ end |

Hi Geoff, Peter, Doco issue: On Page 74 of doco, the table shows 12-bit as being pixel format ARGB4444 when perhaps it should read ARGB4332 (EDIT: unless perhaps it is that format, but zero-MSbits filled ?) something like a bitmap like: AAAA 0RRR 0GGG 00BB (perhaps a note in the manual if this is the case) Regards Phil.

More research before posting perhaps? This should be fixed in V5.05.06b3 or above. It is the issue Panky found with the memory allocation of pages from modes that need 384Kbytes per page I'm offline for the next fews days. Nimue: please give the new OPTION Y_AXIS a go and find the missing bits. PRINT definitely won't work but TEXT should, Images won't work and sprites won't - there may be other issues. I did say it was a big change! Edited 2020-09-08 17:11 by matherp |

Maybe, just thought a bitmap might be handy to make it crystal clear how the 12-bits is spread out into 2 bytes. |

| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 8592 |
4 bits for red, 4 bits for green, 4 bits for blue, 4 bits for transparency = ARGB4444. Pretty simple to understand - yes? |

Will give this a go today - have a class later, so can test it "live" so to speak. @matherp --> blown away!! Nim Entropy is not what it used to be |

Great, please use the firmware I just downloaded (9:38BST) - still b4 |

I know this is a long-shot, but would it be possible to enable an option for (in the editor) CONTROL + S to be save, and not select? Just want to make sure I state that this is not a complaint, I'm just very very stuck in my ways and a small change like this would be icing on the cake. Pressing CONTROL + R to run would also be a nice option too. Also - not sure if this is a bug or a feature, but if I hold shift and use the cursor keys I can mark text, which is wonderful, but if I page up and page down whilst in this select mode (still holding shift), then the selection is lost. If you could maintain the selection whilst paging with page up and page down then it would speed up my personal workflow. Needless to say, these are ultra low priority and your work is super appreciated. |

Just tested this on a group of 11yos -- they found it much more intuitive and a direct follow on from their graph work -- this allowed be to get them to use the CMM2 to "plot" data. We tested the basic drawing functions; LINE, BOX, CIRCLE and ARC (the only thing with ARC is that the orientation is now the other way round -- but that's not a problem to get their heads around). Thank you for this tweak -- this and the OPTION ANGLE have made the CMM2 even more suitable as an in class tool. Cheers Nim Entropy is not what it used to be |
