- PCB of a Zigbee plant watering sensor
This week I ran a poll asking engineers the IDE they use for C programming. I had been surprised by two things. The first one is the very low percentage using Eclipse. Only 10%. The second one is the very high percentage using VS Code: 53.2%. I hadn’t realised how VS Code became dominant.

Testing of Event-Driven Embedded Software with Python
In this presentation in two
parts
, Miro Samek demonstrates how replacing mocks
with spies and using a proper software tracing tool makes your testing easier and dynamic. Miro Samek is using his
company’s tools, but the point stands and several other tools on the market provide the same features. If the concepts
and differences between mocks and spies are blurry for you, I suggest reading the
TestDouble
article by Martin Fowler.
Tiny Tapeout 2 is open for submissions
Tiny Tapeout,
Matthew Venn
’s project, is probably the easiest way to get
your design manufactured on a real chip. The second run, currently opened, will close on Nov, the 14th at 18:00 CET.
You still have the weekend to submit your work and to see it integrated on a real chip.
