 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. |

A "because it can be done" project. :) Very neat but probably of very limited use. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

there may be the odd niche where it could be useful. for instance, if you wanted a small auxiliary processor to handle USB communications with zero interaction with the two main cores. a bit like how the 16F1455 processor handles USB for the MX170/470 on Explorer boards. cheers, rob :-) |

It goes to show the flexibility of the RP2040 architecture. I suspect this possibility wasn't part of the original design. Usually someone will find a way to make things do what they weren't intended to. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
