@ShawnHymel I like to create example projects after each chapter or session to help me understand and solidify what I just learned. This process also has the benefit of providing snapshots for a project that spans across chapters or sessions.

@MicrochipTech Thanks.

[John W Woolsey @JohnWWoolsey]

I was alerted today about an issue discovered in the MCP23017 I/O Expander chip by @MicrochipTech concerning use of the chip's GPA7 and/or GPB7 pins as inputs. The datasheet was changed to reflect that those pins should only be used as outputs.

Hopefully, a fix is in the works.

@Elektor @alranel @arduino Why did Arduino decide not to add an IMU to the Uno R4 WiFi? #elektorei

[John W Woolsey @JohnWWoolsey]

Purchased the new Arduino Uno R4 WiFi on release day from @arduino. Looking forward to some play time to test out all the new features.

I just published an update to the following @WoolseyWorkshop article that uses the latest Sphinx version and adds type information to source files.

Just posted a quick tip on @WoolseyWorkshop on how to document CircuitPython programs on your primary computer.

Today, I discovered that I can use the Sphinx autodoc_mock_imports option within the https://t.co/nY6adtmQPE file to mock those libraries.

I can now successfully generate Sphinx documentation for my CircuitPython programs on my Mac. I'm a happy camper!

[John W Woolsey @JohnWWoolsey]

I have always generated Sphinx based documentation for my #CircuitPython programs using Blinka on my Raspberry Pi board since the necessary Core Modules, e.g. board, digitalio, etc., are not available on my main computer.
