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

What I‘ve figured is that the nRF port has the micro:bit FS enabled as default which only supports flat file hirarchies (no directories). Also, I see that os.listdir(‚.‘) reports an error about an argument given... both of which might relate to the problems you see. There is a small section in the r...

Re: [nRF52] Here is tested and working "proprietary" radio demo code

It doesn't rely upon nor use softdevice.

Re: [nRF2] Here is tested and working "proprietary" radio demo code

I‘m wondering how the softdevice coorporate with this... do you include it in your flash output at all?

And just a small thing: please rephrase the title of this thread so it reads correctly („nRF52“) - makes it a lot easier to search.

that is great, thanks!

Do you mind sharing this as a git gist or even as a git repo so that scanning through the code and making comments is easier?

Re: HDC1010 I2c with pyb1.1

scanning through the datasheet.. . that is a standard memory mapped i2c device. so you should be fine by using any of the i2c.memread/memwrite functions. start ln the repl, do a scan first. then try to read the device id. once that works, you should have no problems initiating the measurement functi...
