Re: PYBD WBUS connector

Now that we know what connectors mate to the D series I would like to know how to place these connectors on a PCB for the PYBD to mate to. I cannot find a drawing that shows the coordinate locations for the connectors. Anyone have a link?

Thanks

Extended Length Socket Pins

I would like to use the PyBoard in a project where I plug it into a board that I am designing. I would like to know of a part number or manufacture that makes extended versions of the rounded socket pins that come with the PyBoard. I want to keep the option of adding shields to the PyBoard so I don'...

Re: frequency counter

Dave,

Thanks for the suggestions. I will report back on my progress. Copy the 32-bit timer. Since I am measuring a known frequency and just tweaking to get better that 5ppm, a 16-bit would work, but 32-bit would be more robust and allow for testing with unknown frequencies.

Take care,

Rich

Re: frequency counter

Dave, I am doing something similar. My application is crystal calibration of a BLE radio. I can set up a 6MHz output on one of the radio IO pins to input to a pyboard as a clock input, hence, using the PYBOARD as a frequency counter gated by a one pulse per second (1pps) output from a GPS receiver. ...

Where's the source?

I would like to build MP for the Pyboard D. I have lots of code that I can only run if I "freeze" it as well as small changes I need to make for my environment. I don't see it in the main MP repo. Is it in plain sight or not yet available?

Thanks

NFC Tag, was Re: Porting to Nordic Semiconductor nRF52

Does anyone know if there has been any work in exposing the NFC type 4 tag interface of the nRF528240 within micropython?

Thanks

Re: Anyone working on a port to Nordics PCA10059 Dongle?

If anyone else views this thread and can make a suggestion, I am all ears. I copied the nrf/boards/pca10056 directory and made a pca10059 directory. I can build the package. Next, I ran: nrfutil pkg generate --debug-mode --hw-version 52 --sd-req 0xA9 --application build-pca10059/firmware.hex build-p...

Re: Anyone working on a port to Nordics PCA10059 Dongle?

NM. I started from scratch, followed the instructions again and all the build steps worked. Trying to target the PCA10059 board now. I think I started from an old clone.

Thanks to you both for answering my question.

Re: Anyone working on a port to Nordics PCA10059 Dongle?

Oh well. My boards came, but I am dead ending on how to build it. I followed the build instructions you provided a link to Peter. There is stuff missing, because when I go to build (following the example), I get fatal errors indicating nrfx.h is not available. I downloaded the drivers. Any suggestio...

Re: Anyone working on a port to Nordics PCA10059 Dongle?

I ordered both PCA10056 and PCA10059 boards so maybe I can see what needs to be done when the boards arrive. The nice thing about the PCA10059 is that it takes DFU image downloads over USB like the PYBoards.
