Re: Esp32 port

I am very happy to report that, after some discussion, Pycom will be joining forces with us on the ESP32 port! We will be merging our efforts and code and the core ESP32 port will be MIT licensed with contributions from Pycom. Here is their announcement (see their forum https://forum.pycom.io/topic/...

I'm using the LoPy, but it's also known to work on the SparkFun ESP32 Thing.

Re: Esp32 port

@marfis thanks for starting this topic. As it says in the README, this ESP32 port was sponsored by an Australian company Microbric. They were very keen to see an MIT-licensed port of MicroPython to this chip, so that they, and other people, can use it freely in their own products. The core of the po...

Re: Code breaking change to stm module

This was an unintended breaking-change. The constants stm.GPIO_BSRRL and stm.GPIO_BSRRH have been added back to the module (for F4 MCUs only). Although these constants will stick around, it's recommended to use just GPIO_BSRR, to conform with the datasheet of the microcontroller.

Re: WiPy 2/ESP32 specs and performance

I now have a LoPy board and have run some basic tests to see how the ESP32 compares with the ESP8266. I'm using the latest firmware from Pycom, 0.9.3.b2. It's hard to tell what version of uPy it is based on because the git hash doesn't correspond to anything in the main uPy repository. The time modu...

Re: Downloading 1GB of data with MicroPython ESP8266 port

I had a go with @pfalcon's test_dl.py script but didn't get very good results: after running for a few hours I only managed 1 full download of the 24mb file (SHA passed). Other tests either had ETIMEOUT or only downloaded part of the file and failed the SHA. It ran at about 6k/s which is pretty slow...

Re: const no longer a keyword

"const" was never a keyword in the strict sense of the lexer (eg "for" is a keyword). The recent changes to "const" usage are the following: ⋅  micropython.const(x) function was added, which just returns its argument. ⋅  all Python scripts in the mic...

Re: RFC: Moving forward with the WiPy/CC3200 port

Sounds OK, but in time it will leave the final release v1.8.6 undocumented. Or will a snapshot of the docs be available somewhere? The idea is that with the versioned docs that we currently have, you'll be able to refer to the docs for v1.8.6. And because of the magic of git, one can always checkou...

RFC: Moving forward with the WiPy/CC3200 port

Hello all WiPy/CC3200 users. The WiPy 1.0 is no longer in production, but there are still many of these boards out there, and there is also the generic CC3200 LAUNCHXL board and possibly other boards created around the CC3200 chip. So I would like to see the CC3200 MCU supported for a little bit lon...

Re: Embedding with frozen code

Frozen bytecode was designed so it could be the last step in the compilation phase, and nothing earlier depends on it. So, yes, you should be able to build the uPy library and then do frozen bytecode at the end (and if any of the frozen scripts change you should only need to rebuild frozen_mpy.c/o)....
