The code makes no sense. Play TONE isn't blocking so you are changing the frequency as fast as the program can run. Start with a simple PLAY TONE 300,600 at the command line and see if you get sensible tones |

Hello, in fact, the program is useless, or pointless. At least for me. I'm just experimenting a bit, havin fun;-) PLAY TONE x,y,z plays perfectly. I hope this bit of code handles the "non blocking" of Play correctly? For d = 200 To 4000 Play tone d, d ' Pause 1 Print d Pause 1 Next d This also produces "incredible noise" on the left channel. But that's not important, there are certainly enough other "construction sites" for you. THX |

Can we assume from the quote that the H/W is fine and you are suggesting there is a S/W bug? In which case I assume the same would occur on any other PicoMite audio? Please try the attached For d = 200 To 4000 Play tone d, d+1 ' Pause 1 Print d Pause 1 Next d and see if the problem disappears Edited 2024-02-19 20:02 by matherp |

Hi, the code makes similar, but less noise and crackling. Google Translate: "hissing and crackling" ;-) The hardware is ok. |

Try this PicoMiteVGAUSB (2).zip Do For d = 200 To 4000 Play tone d, d Pause 0.1 'Print d Next d Loop |

For RTC auto enable to work, you need to set first OPTION SYSTEM I2C GP14,GP15 Volhout Edited 2024-02-19 21:51 by Volhout PicomiteVGA PETSCII ROBOTS |

Thank you, missed it after flashing new firmware and settings new options  Peter has printed it on the solder layer of the PCB;-) Now i will put it in a plain text file so i can copy and paste when necessary. Thank you again for giving me your board! Dietmar |

These can be useful also. OPTION DISK SAVE fname$ OPTION DISK LOAD fname$ |

Hi phill, I hope you don't mind me taking a different position. I think OPTION DISK SAVE and OPTION DISK LOAD are the least usefull commands in MMBasic. Their only use is if you want to force a PicoMite into illegal CPUSPEED (378). I see 2 users 1/ The user who loads a release MMBasic (from Geoff's site). They neve have to change the OPTIONS once they are set. And when they would change (add new) it is not going to be in a disk file anyway. 2/ The beta version users/testers. These people get a new version every week(s) and could benefit from disk saving and disk loading OPTIONS, but in many cases -or in debugging- you will loose the A:/ drive. So the OPTION DISK FILE is on B:/. But to get to B:/ you have to enter OPTIONS (either SDCARD or SYSTEM SPI or both). And that means that you have to enter options manual anyway. Even in Linux (with Putty restarting every time you enter an OPTION that changes IO or CPU) it is 2 minutes to copy the 6 lines from a text file (line by line) into Putty. Teraterm (windows) doesn't restart, and then it is even easier. Regards, Volhout P.S. phill, you should be sleeping now. It is 02:00 at night. ZZZZZZZ... ZZ.

it would be so much simpler for everyone if persistent OPTION settings were just read from a plain-text file called "config.txt" on the A: drive. cheers, rob :-) |

The joys of options. I find entering a set of options to be a nuisance. My windoze/teraterm combo looses the connection with each typed in option. The A: drive is likely empty after a firmware flash, but XMODEM is fine for transferring an OPTION file over before using "OPTION DISK LOAD fname$". What if there were a means of setting multiple/all options in one go? Visit Vegipete's *Mite Library for cool programs. |

copy and paste options to notepad and save as text/name |

So, how would you specify which SPI port the SD card was on and which pins it was using for what? :) I like OPTION DISK SAVE and OPTION DISK LOAD personally. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Accepting there may be complexity that I am unaware of, you shouldn't need any of that set to read a file from A:/ Best wishes, Tom Edited 2024-02-20 03:11 by thwill Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

If you stick to full releases and you are using a fixed H/W environment you only need to load the options once - no big deal Under most conditions options are even preserved when doing a firmware update. The need to load options only happens when I make a change that alters the flash layout and in that case the A drive is also deleted so it would be utterly pointless to read the options from the A drive. DISK LOAD does exactly what was requested above - loads all the options in one go. Many options are used to configure things very early in the boot sequence and so it is completely impracticable to read them in from a disk file on each boot up. It stays as-is so accept it or use a different platform |
