ch32v307 VS MicroPython

VCC-GND Studio is about to launch similar boards based on CH32V307.

But if you're looking for RISC-V + integrated PHY, take a look at WCH's CH32V307 - just add magnetics, termination and an RJ45 jack and you've got 10BaseT.

Yes, English datasheets can be found - along with code examples, board schematics etc - at the openwch/ch32v307 Github repo.

More realistically, I DO think there's value for a terminal server that's just an ethernet connection (even one that's ancient) with some amount of programmability that's connected to 80 GPIO pins, some of which may be serial ports. I could imagine testing 1-2 Raspberry Pi-class with a bed of nails style test jig that confirms that all the GPIO, JTAG, and such are at least toggleable by sending synchronized signals to the BeagleBone/VisionFive/ESP32-C3/ whatever to confirm that all the I/O pins survived the fine wires from the wafer to the package plus all intervening PCB vias and soldering and so on. (Maybe you can't test board X with another board X because there's a different number of inputs and outputs.)

looks to be IMAFC from the PDF on their github (https://github.com/openwch/ch32v307/blob/main/Datasheet/CH32V20x_30xDS0.PDF)

Just putting my hand up to say that MicroPython is awesome (and runs on the RP2040). https://micropython.org

Gah, I just ordered one on impulse [1]. I've wanted to build out a WiFi PDA for quite some time now and I like this hardware.

I'm quite liking the idea of running tulip MicroPython [2] on it, or going back to pure MicroPython [3] and writing some drivers. Apparently something like ampy can be used to upload/download Python files [4].

Threads could be quite exciting for running multiple programs at once [5], although I have no idea what it means for two programs to fight over GPIO! It does seem as though MicroPython can only utilise a single core [6].

If you really want to engage in the travesty that is shoehorning a high level scripting language into an environment that has 512 bytes of RAM and less clock cycles than an electric toothbrush, there is micropython.

There is some work to implement a common CAN interface in micropython but it's some way off yet: https://github.com/micropython/micropython/pull/13149

There's an iperf opkg pkg, or is it just netperf (which works with fluent)?

Needed for hobby project, maintained by very small team. Haven't decided on specific microcontroller. Needed for general bit-banging, speed and code size are not priorities.

So far have considered MicroPython [0] [1] and Lua [2] [3], but open for suggestions for others.

What are experiences?

Python is also a general-purpose programming language. It's typically used on desktop / laptop computers. But Micropython is a variant that can be used to program embedded devices.
