disable NFC on nrf52840

Hi all,

In mpconfig.h, I don't seem to find the constant enabling/disabling NFC on the nrf52840. I am specifically trying to compile for blyst, and would like to use the two pins assigned to NFC for other purposes.

I was able to build micropython with ulab for teensy 4.1 without too much trouble.
I know that this is a somewhat old post, but I was wondering, whether you would care to add your build instructions here https://github.com/v923z/micropython-builder, so that other would profit from it.

Re: Installation help with ulab

You can also download the (almost) latest micropython and ulab from https://github.com/v923z/micropython-builder. You can also find build scripts there that should just work.

Re: ESP32 firmwares with single/double precision and ulab module

I can load this firmware successfully. But this ulab is not full. https://gitlab.com/rcolistete/micropython-firmwares/-/tree/master/ESP32/v1.12_with_ulab/ulab_v0.54.0_2020-07-29/Generic_flash-4MB No, that is a very old version. But when I load this firmware, this error occurs. It seems successfully...

Re: ESP32 firmwares with single/double precision and ulab module

It is not quite clear, where the firmware came from, so it is a bit hard to comment on the issue. Have you read the relevant section of the readme: https://github.com/v923z/micropython-ulab/#esp32-based-boards? Also, is this issue related to ulab, or would you have the same problem, if you compiled ...

Re: ESP32 firmwares with single/double precision and ulab module

Unfortunately. Cant install. The documentation that I linked to is quite detailed. When you say you can't install it, what do you refer to? The toolchain, or the firmware, or something else? It is a bit hard to help, if the circumstances are not known... And cant see that anyone install it for esp3...

Re: accessing list dictionary from C

hi there, I'm just wondering how mp lists and dicts are accessed from within C. Background is that I want to accelerate some software by implementing native modules which is - to my mind - really an intersting thing but sadly not well described.. A whole section is devoted to this subject here: htt...

Re: MP 1.17 + ulab = too big for TinyPICO?

You can also try to reduce the number of dimensions, or remove functions that you don't need: https://micropython-ulab.readthedocs.io ... e-firmware You can really save a lot by including only what you need.
