 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. |

Interesting little board from Adafruit....low cost too ! Maybe it would run various 2040 projects (?) 2040 |

Check out the PCBs in my sig. The ArdoMite got there first. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Interesting ! Ardomite needs a sdcard socket...(?) Have you tried the Ardomite with the philearlehower software ? I guess that the adafruit board will either/both run that or arduino IDE, although I cannot see any definite mention. Edited 2023-11-27 23:49 by zeitfest |

ArdoMite was designed round the PicoMite, not the Pico itself. At the end of the day it's just another Raspberry Pi Pico wired to terminals so it should run anything that that can. It was designed with a micro SD card socket because at the time the PicoMite didn't have an A: drive. Of course, the SD card is connected over SPI to suit the way that the PicoMite works. There is a second "S" version where all the connections are on a 0.1" grid - the way the Arduino *should* have been designed. :) You can make "hats" out of any 0.1" matrix board.

I looked at this , is the object at the top left hand the socket ? I didn't recognise it, a bit sleepy at the time sorry !. Standard uf2 files should work then I guess. The arduino format has a lot of products off-the-shelf of course, ironic really - AFAIK it was deliberately designed to be not popular so as to avoid "losses" in teaching classes. |

Yep, that's the micro SD socket. :) I tried to get it reasonably compatible, but some things I simply couldn't do. It's not guaranteed to be compatible with Arduino accessories. That doesn't bother me because it's supposed to be programmed in MMBasic anyway. :) Note especially that the IO capability of the RP2040 is less - it can't drive the same GPIO pin current. You can't, for example, put a 10mA LED on more than a couple of pins at once. It's also restricted to 3V3. It comes into its own if you want to use the blank Arduino "hat" boards and put your own circuits on them. Physically it's as close to a drop-in replacement as I could make it, so probably of some use to those who strongly dislike the Arduino IDE and anything resembling C (like me).
