Re: Simple terminal (VT100) editor widget (and other widgets)

I know this is an old thread. I tried running picotui on micropython 1.11 without any luck. I am seeking a text based GUI for micropython embedded (not linux), specifically for the STM32 variant. Any information is appreciated.

Thanks

Getting RuntimeError: maximum recursion depth exceeded

I am running some code using the shell.py module In the cmd.py file there is the following line: argsresult = re.match("(\w+)+\s+(.+)", arg) Normally this does not cause a problem. I have the shell running in a separate thread and when I feed it "activityLED" or "abcdefghLED" I get the max recursion...

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

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.
