Re: Espressif announces ESP32-S2

Espressif is planning on using TinyUSB in the ESP-IDF for the -S2 (https://github.com/hathach/tinyusb/pull/282) so adding basic support should be easier in MicroPython (which uses TinyUSB for SAMD and nRF) and CircuitPython (which uses TinyUSB for most ports.)

Re: Bluetooth `addr_type`?

My guess (haven't used it myself) is that it's an int value that matches the value in the BLE spec. Address types are usually "static public", "random static" (here is a Nordic post about it https://devzone.nordicsemi.com/f/nordic-q-a/2084/gap-address-types), or two others derived from the bonding k...

Re: How to invoke own method from C?

We recently ran this down in CircuitPython because we wanted native code to have access to the instance rather than just the native struct. (Our PixelBuf class calls `_transmit` on the subclass.) Here is the PR: https://github.com/adafruit/circuitpython/pull/2550 There was definitely work to make th...

Re: How to port Micropython to new Microcontroller

Ok, I'm now attempting to do it myself... But being a beginner working with GIT I'm having some difficulties. I forked the repo and created a new branch: https://github.com/st-arnold/micropython/tree/same54 Modified/added files under ports (basically just copied all D51 stuff to E54 as a template a...

Re: About MicroPython‘s trademark

My understanding is that the MicroPython trademark is governed under the Python trademark that is owned by the Python Software Foundation. (This is true for CircuitPython as well.) I'll mention this to other's here at Adafruit and would encourage you to reach out to the PSF as well.

Re: Need help with Makefile for ATMEL SAMV7

mattyt, let me know if I can answer any of your questions about SAMD. I'd be happy to see MicroPython support for the SAMD series.

Re: fast font rendering on graphical displays

Hi Matt and Zoltán, I'm curious about your use cases for text and in what way speed matters. Is it initial time to display a static value or rapidly changing values like a terminal while compiling? I'm working on text for CircuitPython at the moment and am thinking about it a lot. One thing I defini...

Re: How to port Micropython to new Microcontroller

baristajosh, CircuitPython (a fork of MicroPython) supports the SAMD51 which is very similar to the E54 I believe. So, I'd suggest starting there. Once you have CircuitPython going on the E54 you should have enough knowledge to backport SAMD support to MicroPython (which other folks would like too I...
