 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. |

At what point does it become cheaper to use a bank of Picomites instead of a single Propeller P2 and get *true* asynchronous multitasking? Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

For me....different animals; The ultimate MCU is the MMBasic family but the Prop is like an FPGA that mere mortals can program as easily as a mite. Apart from the eight CPUs, the 64 pins are processors in their own right. They can be 16bit DACs or 16bit ADCs. One of the eight CPUs can handle 16 high speed UARTs simultaneously. I prefer writing BASIC code but if I need a C function, I just make a class out of it and include it in my BASIC source and the same thing goes for a SPIN language function. Inline asm, etc. No interrupts required and so no jitter/latency. You can't get better real time. Mite + Prop is a killer combo that even grunts like me can do amazing things with. I read the other day that the P2 is something like 14 Euros. I have the "KISS" module which is very similar to Pete's RP2350 DIL. Looks like I can get them produced by JLCPCB because LCSC now has the P2 chip. |
