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...

Re: [nRF52] How to get rshell to work with an nRF52?

That sounds like it will work but I haven't done it that way myself. I've only done it with a JLink at this point. One other option would be to install the nRF UF2 bootloader first and then use the CircuitPython UF2 to install it. The bootloader's repo is here: https://github.com/adafruit/Adafruit_n...

Re: [nRF52] How to get rshell to work with an nRF52?

I noticed Mouser now has the nRF52840-Dongle in stock for $10. I've been waiting for a supported BLE MicroPython chip. Is rshell compatible? Are prebuilt binaries available? How does the MicroPython port compare to the CircuitPython port? (CircuitPython dev here.) At this point its pretty different...

Re: SAMD21 board..slow SPI?

Hi Mark,
Please post on the Adafruit CircuitPython forum here: https://forums.adafruit.com/viewforum.php?f=60

That's where we support CircuitPython.
Thanks!

Re: Installer Fail

Hi qstyk,
Please ask for CircuitPython support on the Adafruit forum here only: https://forums.adafruit.com/viewforum.php?f=60 and on Discord: https://adafru.it/discord.

Let's not bother the MicroPython folks with CircuitPython specifics.
Thanks!

Ah, thanks for the link! We really do need to clean up some of those obsolete docs. Much appreciated.

Re: How to convert a CCS811 CircuitPython to Micropython for ESP8266

FYI, it is documented here: https://circuitpython.readthedocs.io/projects/bus_device/en/latest/adafruit_bus_device/index.html#adafruit_bus_device.i2c_device.I2CDevice.readinto If start or end is provided, then the buffer will be sliced as if buf[start:end].
