[sdiy] 4-bit encoder?

[Ullrich Peter]

Hi Ingo!

Small correction: there are Chinese 8051 clones running at the faster 12x speed and only cost some cents as the Cortex M0+ chips...
Chinese engineer love to use them as they are cheap and mass production available.

[I learned this in a project of a friend that found an investor in a TV show and they completey designed the gadget from ground up with a complete different microcontroller - one of these 8051 clones...]
[And yes there are also AVR clones - some faster commands and much cheaper...]

Ciao
Peter

Come on guys, don’t exaggerate.
Ten years ago, I was convinced that the 8051 was immortal. And now? Sure, you can still get it (from Atmel for instance), if the original used the classic 44-pin footprint. But for how long from now? Anyway, it’ll cost much more than, say, a Cortex M0+ processor. And if you need one of the gazillion formerly existing pinouts (like the LPC9xx series from NXP), you’re out of luck.
