Re: Porting to Nordic Semiconductor nRF52

Success! Once I bumbled my way through installing the right dependencies and adjusting the Makefile to deploy to the correct tty port on my machine, Micropython is now running on the Adafruit Feather nRF52 !! Great work Glenn! I'll supply more details shortly - and I'll try to write a README that wa...

Re: Porting to Nordic Semiconductor nRF52

Damn Glenn, you've been busy! I really don't have any breathing space until tomorrow evening but I'm going to try and generate a build in 'spare time' at work today... ;)

Seriously good work mate, I'm hoping to test it out soon.

Re: Porting to Nordic Semiconductor nRF52

Hi Glenn, If you haven't already got something up running, i will try to answer your comments and questions as best as i can. It would be great to get this board up running! I'm keen to get it running too! The repository name "nrf5_no_sdk" might also be a bit misleading. Softdevices are still used i...

Re: Porting to Nordic Semiconductor nRF52

OK, so my Adafruit nRF52 Feather arrived this week! Nice bit of kit. Looking at the Memory Map of the Feather as it's delivered, it seems that I have some work to port the nrf5 branch of Micropython to this device... I'm assuming that the Micropython build is larger than 156KB? If so, I'm going to h...

Re: Porting to Nordic Semiconductor nRF52

Thanks for the update Daniel and Glenn! That clarifies the situation a lot. Seems like you guys have been busy!

I think I will purchase one of the Feather nRF52 boards - I haven't had a heap of spare time lately but I'd like to think I could find a little bit of time to help with a port...

Re: Porting to Nordic Semiconductor nRF52

Just wondering about the status of the nRF52 port? It looks like it's active (I see commits as recent as within the past day) but I don't see a lot of discussion on the forums... For reference I'm looking at: https://github.com/tralamazza/micropython/tree/nrf5_no_sdk I also note that there's a 'nrf5...

Re: what filesystem used by micropython

Timely! I was just reading this interview with Damien: http://hackaday.com/2013/11/27/interview-with-damien-george-creator-of-the-micro-python-project/ where he mentioned that the MicroPython FAT implementation is closely based on FatFs by ChaN: http://elm-chan.org/fsw/ff/00index_e.html Just in case...

Re: Watchdog in ESP8266

I haven't personally used the WDT on the ESP8266 yet but was planning to...while researching how to use it I came across this issue: https://github.com/micropython/micropython/issues/2154 If I understand correctly, a 'standard' WDT (where you must 'feed' it within a specified timeout to avoid a rese...

Re: I2C implementation

Hi Robert, Yes, I2C is implemented with bit banging on the ESP8266 and I2C can be bound to any GPIO. The reason the Huzzah Feather labels particular pins as SDA and SCL is alluded to in the Feather Huzzah Pinout [1] - "In theory you can use any pins for I2C and SPI but to make it easier for people u...
