Re: ticks_diff not behaving

can't really explain it but just to note a couple of things: ticks_diff should return invalid values if the difference is higher than 2**29-1 (as described in the docs). From what I see in the repo this value is the same for all platforms (`MICROPY_PY_UTIME_TICKS_PERIOD`) and works as expected on th...

Re: hiding python code on the board

To make things a bit harder why not: 1) disable REPL (do not compile it into your FW) 2) disable debugger access (blowing JTAG fuse) 3) enable HW security features, such as readout protection 4) bytecompile as much as possible If JTAG lines remain enabled it's no problems to readout and reverse engi...

Re: Docker image

numerous points.. a lot of them you'll find on google. it isolates your cross dependencies. you can run an ubuntu image on osx similar like a VM but without the additional overhead of a full fledged VM. The dockerfile is also self-describing. if you ever need to reinstall your system, just use the d...

Re: Esp32 port

Please try out the port if you have an ESP32-based board and let us know of any issues. Note that if you use a Pycom board (eg LoPy) you'll need to select the antenna type for the wifi to work. See the esp32/README.md for some details on this. I tried it out tonight on my WiPy2.0 - I'm on OSX and I...

Esp32 port

Up to now I was not aware that there is a esp32 port in the official uPy repo: https://github.com/micropython/micropython-esp32 does anybody know how it compares to the pycom fork? It's partly sponsored by a company called microbric. Damien mentioned in the readme: If there is enough interest in the...

Re: Adafruit CircuitPython

Maybe the answer is the more the merrier but with limited resources it does feel like a missed opportunity to combine efforts v. separate initiatives well it has started already with pycom's forks of uPy and adafruit is now the next one. I feel it has something to do with the machine API and its en...
