I took the holder off and hot-glued a CR2032 one on. They are dead easy to get. :) Yeah, the UK lost "Woolies" many years ago. :( Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

+1 as well! Never got them to work, but STILL on the shelf...just in case 'someone' succeeds. |

Gosh, yes, I forgot about the DACs. At the moment I just revert to PICAXE for simple DACs. It would be brilliant to have a workable 'Mite with DAC. If I remember correctly, the only other 'Mite with a DAC was the Armmite H7, but those are not exactly off-the-shelf anymore. |

Picaxe ... er got gcbasic and it was better and you can use a lgt328 which is 32MHz and 12 bit a-d. just saying as rpi mmbasic I use most but 8 bit is still valid. |

Thanks, yes, but of course. I, however, have an old stock of PICAXE chips left over from before the 'mites and this is one of the fairly few applications that I put them to today. As ever, "other chips are available" but it was PICAXE that first got me into microcontrollers many years ago and I stepped up to MicroMite with the 150 chip in its infancy. |

Just before I got into 'mites I was using GCBASIC on PIC chips. That's a brilliant system. It had the advantage that Microchip have (or at least had) a very nice policy regarding sample chips. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Oh, dear! Now you have triggered another past idea. I had, somewhat briefly, explored the idea of GCBASIC several years ago, but like you, I became entranced by MMBASIC. The idea of using simple eight-pin chips for straightforward applications is where GCBASIC would be ideal. The concept that I am now more likely to just grab a Picomite and use it for a ten-line programme seems ridiculous - a 32-bit processor with all the extras - but cost-wise it can be cheaper than some of the microcontrollers from Microchip! Which is probably why I keep a stack of Picomites on the shelf - unless I want DAC... Perhaps I should look again at GCBASIC...if I can find the time. |

My last GCBASIC projact was a "visible computer" which should have been built from logic gates. I put groups of gates together as GCBASIC programs and put them into PIC chips - a bit like little ULAs. There was no standard logic (IIRC I did use a static RAM chip though). A complete waste of time and effort really, but it was fun. :) --------------- Currently trying to hard wire an F4 to a SSD1963 back-to-back without using a PCB to make the connections as I can't afford to get one made at the moment. It's a nightmare of crossed over wires. lol Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

It has been the recipient of some excellent work from Mr.Venn just recently and GCBasic is still a very viable path. The ability to make those little PICS do stuff at lightning speed and approach functionality of the MMBasic world *** as a micro-controller *** is very nice. The problem with those little 8 pin chips (I still got about a hundred of them) is they have tiny memories. I produced a Hard Air Gap for ethernet using a 508 (0.5K) and it was the perfect solution for a twinkle of intelligence in a very simple project, but not an ounce of spare space left. My gauss meter is the same, simple read the sensor, display the result with some maths and intelligence around changing the probe for higher readings... very nice. What I like about GCBasic is you can see the compiled ASM file and tweak if necessary. I get a kick out of seeing how bits of code I wrote convert to PIC ASM.

What do you think your PC is ? 8 or 16Gbyte of memory with octal core 2GHz processor, just to type 2 lines of E-mail ? You are not trying to go back to a ZX81 becuase it has 1k memory that wil sure fit the 2 lines of E-mail..... Volhout PicomiteVGA PETSCII ROBOTS |

$3.44USD from JLCPCB with the gerbers from this post, but that's with slow boat shipping, so happy wiring. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

I know about that design but I'm afraid that current financial problems rule even that out. Still, I have connectors, wire & solder and there's no real rush. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

So are you making something like this!  Latest F4 Latest H7 FotS |

| Mixtel90 Guru Joined: 05/10/2019 Location: United KingdomPosts: 7938 |
Very vaguely. I'm trying to get the F4 and the display back to back so that the IO pins are still accessible. I could probably do it using 90 degree connectors on both and a small PCB at right-angles to them, but I can't do that at the moment for financial reasons. It's currently a "plug" onto the display arranged with wires all coming off it "downwards", towards the display, then a normal connector on the display. Unfortunately it's not a good arrangement for getting wires onto the right terminals! Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

That's interesting, but may I ask what the jumper selector does and what the resistor is for? I presume that this is for an SSD1963 display? |

| disco4now Guru Joined: 18/12/2014 Location: AustraliaPosts: 1003 |
I think its for an ILI9486 P16 with 34 pins. Resistor is a pullup on CS for SDCard I think , I think jumper was to put GND on CS instead of thru to Armmite pin. Was in the early days when getting the ILI9486 to go so can't remember exactly. Latest F4 Latest H7 FotS |

Hi , Some years ago it was a project with mmbasic on the stm32f746g-disco board. You got the lcd , audio , sdcard , mems microphones etc... all in one board that was more practical than connection all around a base board ;) Why not just use a board like this that cost less as if you buy each part separately ? URL: Original link And in this forum : MMBasic for stm32f746g Disco Cheers. Theory is when we know everything but nothing work ... Practice is when everything work but no one know why ;) |

Manual downloaded, printed, cover added, volume bound! Bedtime reading sorted! A5, two-sided printing. Thermal spine bound as a soft-back book -looks great. Thanks, Gerry; as the author of eleven textbooks I know just how much work goes into compiling a document like this and I deeply appreciate your effort.  Edited 2023-08-24 01:03 by circuit |

Does the binary indicate that it's version 24 of the manual? ;) Very nice! Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
