 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. |

EEVblog video... Perhaps Peter the miracle-worker, can port MMBASIC to this thing.  I'm joking, naturally. Smoke makes things work. When the smoke gets out, it stops! |

That's really impressive - and a good replacement for some of the PIC range. Microchip might have some of their work cut out if these things catch on.

going RISC5 is a good thing, assembler becomes portable outside of a single supplier |

Have they made the I/O portable? i.e. unlike ARM - where every major chip maker designs their own I/O thus making MMBasic need a pile of new I/O code for each change of chip. John |

RISC-V specifies the instruction set and some extensions (you can also have non-standard extensions). I suspect that any IO handling will be down to compiler libraries for the hardware you are working on. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Thanks. Essentially the same situation as ARM, then, so will need lots of effort to port MMBasic (*), it seems. If the CPUs are cheap enough & powerful enough, with guaranteed availability, may happen I guess. Meanwhile the RPi Pico is excellent features & performance for the money! (*) MMB4L probably vastly less work :) John |

sadly unlikely any port with the flash and ram sizes, certainly this particular chip |

I do need to stress that I was in no way suggesting that MMBASIC could or ever would be ported to this device - note my winking face emoji in the first post.  10c and you get a UART, SPI, and I2C port, 18 GPIO, 10-bit ADC, 16KB FLASH, 2KB SRAM and and 48MHz speed. Very impressive for a whole ten cents! But with 16K of flash and only 2K of RAM, porting MMBASIC to this thing would be impossible I would think. Peter might chime in here, but I think it is safe to say that will never happen. But you MIGHT see things like Great Cow BASIC moving to the RISC-V stuff - perhaps, but even if they did, it would not be anytime soon. What I'm saying is, don't get your hopes up that these can ever run MMBASIC. Smoke makes things work. When the smoke gets out, it stops! |

Irrespective of the word length they are more targeted at the PIC16-high / PIC32-low section of the market, which is still a very profitable one for Microchip. Nope, not MMBasic territory but a definite opportunity for a BASIC compiler or even some sort of "Tiny BASIC" interpreter. Mind you, if they aren't available we'll never know. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

oh yes! (Are you watching Evan?) |
