 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. |

That's rather awkward due to all the proprietary things (I/Os) in the Raspberry Pi that they refuse to release details about, let alone the code to support them. Would be much easier to go for another good value ARM board (or board family) where far more in-depth data exists. Far more and better I/Os often exist on those, too. Allwinner (A20 etc) chips spring to mind. John |

Better 'quality' does not necessarily 'win the day' (remember VHS and BetaMax video-recording systems!). There are well over 8 million Raspberry Pi's out there and if the speed of this port continues in the way it has over the last few weeks then it will open up MMBASIC to many 'new' people. The ARM boards are no doubt 'good' (even 'great'); but they are also currently a bit too specialist IMHO. And I bet there are nowhere near 8million out there - let alone a multitude of Magazines on the high-street shelf as there are with the RPi. What Peter has achieved with Geoff's code for the Pi certainly amazes me. I'd rather he carry on this outstanding port; and possibly someone else (JohnS maybe?) pick up an ARM board port if they think it worthwhile. Another point to bear in mind is the endless 'add-ons' for the RPi that MMBASIC will effectively have access to. I have already programmed several HATs in MMBASIC avoiding the need to build new hardware modules. The above is just my opinion for getting MMBASIC 'to the masses'; and I truly believe a RPi port is the best approach to give a massive 'boost in numbers' of users. No doubt others will disagree . . . . WW (Edited: Too many spelling mistakes!) For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

But that does not address the point my post was all about: doing without Linux as MicroBlocks asked. Realistically that is not possible with RPi boards. (I'd rather have Linux, but that was not what I was replying about.) BTW there are vastly more than 8 million A20 boards out there! Over 80 million, never mind 8. They typically run Android (which is a version of Linux). And a similar number of A10 boards. Also A31/A33. Etc. John |

Maybe a stripped down linux so that MMBasic is the main thing running. I really think a distribution that includes MMBasic would be the best way forward. Insert sd card, run seup and ready. I am not very familiar with Linux as many others. Most will benefit from that, and it will surely give good exposure to MMBasic and the other micromite versions. I would do it, but it is too unfamiliar for me. Microblocks. Build with logic. |

Trouble is, everything left out of the usual Linux may be wanted by someone and they're liable to fall foul of it, especially as these are going to be the least experienced about Linux (they won't want this special distro otherwise). Someone with plenty of free time to help them will be needed as well as with the time to create and maintain a special distro. Doesn't look attractive! John |

There is NO index.html file in the original ZIP of the webserver (first post) and I have used the HTML code listed by Peter on the last post of page 1 of this page as the content for the non-existent index.html file.. I think that assumption is incorrect. So, in summary, I think I have an issue with there being no index.html file.. Also after the server crashes (by trying to run the index.html file I made from Peter's post) the Pi terminal screen needs to be closed and then re-loaded and file loaded and run before it will respond again.. I assume some port is left in an illogical state when the file crashes.. Can someone please post the correct index.html file please (and main html.bas if my cut and paste version is incomplete).. I do not think it is an issue with my router and or the IP range as the serving goes well for the two graphic images.. it it the index.html file that crashes with Error: Array Dimensions that appears to be the problem. I am probably doing something wrong but please realise I am not a programmer's a$$-hole (well actually I was told that I AM) Kind Regards, Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

Mick if you don't have a DS18B20 connected to pin 11 then comment out all lines with a TEMPR() command. You should then see an index.html page at 10.0.0.50 with buttons (at least) but pretty much useless. If you do have a DS18B20 connected to pin 11, I can't help as I don't have one, but try commenting out TEMPR() commands anyway. Good luck sunshine led Miss you George |

Hi Led, Thanks... You are right no DS18B20 installed.... Yet! That fixed the error I now see a basic temp scale table... I also did a simple index.html that I found on the NET and modified to display my text and show Mister Tiger and that works perfectly.. So I now have it running... Just needing a decent web page (index.html) to couple to it and it will be operational.. I must say though, I am not getting port forwarding to work on my new TPLINK D7 modem... There is no section labelled PORT FORWARDING and I have been trying virtual servers under NAT FORWARDING which seems as close as PF but it doesnt seem to function as I expected.. more play at a later time Thank you one and all this has been interesting to say the least.

Those people could do it just as it is now. I am not suggesting to make an exclusively MMBasic version. Just a distribution that has all the ingredients necessary for running MMBasic on a as minimal as possible Linux configuration for (noobs :) )people to start with. That way nothing can go wrong and every beginners situation will be equal. After that tweak whatever you want and install whatever you want. It is just if you are interested in MMBasic and just use a Pi instead of an mcu it will provide a path with least potential problems. Microblocks. Build with logic. |

Start with NOOBS/raspbian and just write up accurate and complete instructions. Far easier. Still needs someone with time and willing to put in effort. John |

Would installing the NOOBS/raspbian and then the necessary io support and MMBasic not result in a SD card image that can be copied and shared. I do that often with Virtual Machines. If i need a SQL Server i just take my Windows 2016 server with installed SQL Server 2016 image and start up another one. Takes five minutes. RasPlex does it in a interesting way. It uses you PC to create an SD card that can be used in the Pi. Microblocks. Build with logic. |

On my TL-WR841N router, under "Forwarding", "Virtual Servers" gives me the chance to set up port forwarding, both with the same incoming and local port and with different. Of course, TPLink may have changed things between routers. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Mick The html you posted on this thread (page 3) is correct and should be saved as "index.html" in the same directory as MMBasic. If you are getting array index errors make sure you aren't setting option base to anything other than zero. If you look at the html it substitutes array elements 0-11 of arrays sp() and cp() |

I can recommend "Conquer the Command Line" by Richard Smedley. It's a good refresher for those of us who knew enough about Linux to be dangerous as well as folks new to Linux. The contents were covered in issues of The MagPi magazine and is also available to buy as a printed book. |

Hi John, All, I am happy to knock some`idiots guide' (after all I am fully qualified as being a big idiot at times) up when I have a semi decent index.html and time to do so.. The examples were obviously written to have a temperature sensor installed.. My big oversight.. Regards, Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |
