[9fans] Arduino programming on plan 9

[sirjofri]

Hi everyone, happy new year,

Out of curiosity, I wanted to ask if someone has any experience with programming arduino boards on plan 9. The question is not only about writing code and compiling it (as that is probably possible), but especially for sending the binary over to the chip to make it work.

I don't know enough about what protocols are used for that, and how easy they are to implement, or maybe if we even have something like that already using xyz-modem or whatever.

Did anyone do experiments on that already, using plan 9?

  I don't know, but is there an avr compiler for plan9?

  I didn't make such experiments, but think that may be avrdude (from linux) can be ported to plan9.

there is, for a atmel mega128 or some such. za/zc/zl as part of davros, a
tiny os for a berkeley mote variant.

Re: [9fans] Arduino programming on plan 9

[Skip Tavakkolian]

Arduino boards now include arm32 and ESP32 (Xtensa) processors in
addition to atmel AVR.  All of the differences are hidden by Arduino
IDE, which does a good job of plastering over things for these and
many other (not Arduino) boards, including RISC-V boards.

I would think that the most likely boards that could easily be
supported on Plan 9 would be the Pi Pico (arm) and Pico 2 (arm +
riscv) through 5c/ic modifications. Those boards show up as fat32
drives on USB and the binary can just be copied over (e.g. usbfat: &&
cp foo /n/sdUx.y).  I think SAMD21 boards like XIAO would work very
similarly.

The ESP MCUs can be easily flashed via serial.
The protocol is publicly documented:

For debugging, there is jtagfs that paurea (Gorka) made many moons
ago. Most boards have JTAG

Another obstacle, most of the driver libraries require C++ support
(e.g. https://github.com/adafruit/Adafruit_Sensor).

[Noam Preil]

Yeah, but most of them aren't too hard to replace, it's just flipping
registers and bit logic, and we have C++ code to reference for which
registers do what :)

I noticed a few directories were still GPL; they are now MIT.
