<p>For those wanting to have a full collection of PR2040 boards,
here's the <a moz-do-not-send="true"

Nano RP2040 Connect</a> with WIFI and Bluetooth from the Arduino
folks. Tom's sez complete IDE support from Arduino with old and
new regular IDE versions and their cloud-based IDE.</p>
<p>One project I want to get around to some day for the PR2040 is a
structured macro assembler. This boils down to a relatively
trivial parser for the vanilla assembly language with recognition
of some simple macros that do <i>if-then-else</i>, <i>while</i>,
etc for the basic structured programming construct collection à la

written with Dahl and Hoare</a>. There is a very nice
structured macro assembler out there for the Moto 68K and the
source code for that would probably be a good starting point. If
anybody else is interested in this let me know so we can
coordinate a little project. Starting with the TI MSP430 I swore
I'd get back to assembly language after a 20+ year hiatus, but
there was always something more important and it is the case that
assembler is mighty hard to justify with today's "all computing
resources are close to free" situation making C the 21st century
assembly language (and Java the 21st century COBOL, HA!). But the
PR2040 seems like a good target and learning the M0+ instruction
set would be useful for those of us who started with assembler to
get back to our roots. I'm especially interested in interprocessor
lock mechanisms that would allow for some hand rolled parallel
loops using the two cores, assuming the necessary atomic
instructions are not too expensive. Until it's time to jump to
RISC V this little chip seems to me like a wonderful, very general
solution for a lot of target applications. I can't wait to jump on
this after clearing a few figurative decks. <br>
