 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. |

Pleas download V5.07.00b2 http://geoffg.net/Downloads/Maximite/CMM2_Beta.zip This version should fix the various little niggles that have been identified in b1 and adds new functionality as follows: Use: integervariable>>n' for unsigned shift right integervariable>>>n' for signed shift right A new fast settick mode is now available: SETTICK FAST frequency, interruptroutine This allows you to exceed the current maximum rate of 1 interrupt per millisecond (1000HZ) and has been tested up to 50KHz. Obviously if the interrupt routine overruns the time available then interrupts will be lost. If the program is executing a statement that takes longer than the time between interrupts the interrupts will be stacked. An example use would be to output to a DAC dim float s(359) c=0 for i=0 to 359 s(i)=sin(rad(i))*1.5+1.6 next i print "expected frequency ",44100/360 settick fast 44100,myint do:pause 2000000:loop ' sub myint dac 1,s(c) inc c if c=360 then c=0 end sub The final enhancement is to allow you to select the serial port to be used as the console. OPTION CONSOLE PORT n n can be 1, 2, or 3 (default). If this option is set all console output is directed to the specified com port. This allows easier remote operation using a wifi-uart or radio link. Previously you would have had to remove the MCP2221A chip and connect the external I/F to the USB-B connector. If the option is set to other than default then COM3 is available on the USB-B connector. |

I can confirm that on this version Welcome tape works almost flawlessly: the only thing that does not work is quit option - I can move up and down, select programs, run them all just fine, but once I have to confirm that I want to quit (press Y) - it seems stuck. Other apps and games run fine, no artefacts in graphics demos. |

Finally, I can continue the 2A03 (NES) sound chip simulator, maybe with the SETTICK FAST I can simulate the ADPCM channel and I can try to simulator even other sound chips that need a faster interrupt timer. Thanks, matherp! |

Thanks, matherp! You did fix that control S in file manager. So thankful. If a mouse using program like your mouse tester is terminated before it get to close down the mouse port the file manager comes up with the error PIN 33 IN USE. This makes sense. I have been entering controller mouse close 0. Is that the best option? Maybe I can set a search path and add a one-line program called CM.bas. I will have to figure out how to do the search path thing. Thanks again. The mouse makes both the file manager and editor so much easier and intuitive. Thanks once again. |

Thanks Peter, I just got upgraded to V 5.06, you're working faster than I can keep up. Whatever kind of drugs you're on, I need some !! Many thanks to you and Geoff for this great project and all your work. Lou Microcontrollers - the other white meat |

I'm glad @matherp managed to fix the main issues. I think the Quit problem is a bug in my code. I guess I'll have to find time to fire-up the CMM2 and create a v0.5.2. Best wishes, Tom Edited 2021-01-05 10:22 by thwill MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

I can confirm what Rado said about the Welcome Tape. Entering 'Q' to quit and then 'Y' to confirm causes the CMM2 to need a reset. It was fine with version 5.06.00 so something has changed to break it. Possibly something to do with console? Bill Edited 2021-01-05 14:36 by Turbo46 Keep safe. Live long and prosper. |

Thanks Bill. If it needs a reset then it probably is a firmware issue after all. "Lockdown 3 - The Worst Sequel Ever" has just hit the Disunited Kingdom so I'm not sure when I'll get a chance to sit down in front of the CMM2 for long enough to try and reproduce it with a smaller example.

Don't bother looking at it. I know the cause and I know the fix. What I don't know is why the cause is the cause. It relates to some major internal work in 5.07.00 preparing for some new future functionality and I need to find the underlying issue rather than just backing out the changed code. |
