Arduino Python dependencies?

1

Hi All,

I was doing some ESP32 experiments the other day and I recall changing my Platformio.ini, as advised by the creator of a project.

I think it was the framework-arduinoespressif32-libs @ 5.4.0+sha.2f7dcd862a

shown below.

I got a bit lost and those experiments didn’t go well, so I’ve reverted back to my original project.

However, I’m now getting compiler errors, as below ….

PACKAGES:
 - framework-arduinoespressif32 @ 3.2.0
 - framework-arduinoespressif32-libs @ 5.4.0+sha.2f7dcd862a
 - tool-esptoolpy @ 4.8.9
 - tool-mkfatfs @ 2.0.1
 - tool-mklittlefs @ 3.2.0
 - tool-mkspiffs @ 2.230.0 (2.30)

My old project compiles OK, but the section above takes several seconds to get through and is becoming annoying now. Any way to get rid of whatever this is ?

Thank you

Does that happen with the latest

platform = https://github.com/pioarduino/platform-espressif32/releases/download/55.03.31/platform-espressif32.zip

too?

Hi Max,

I’m on an old Win 7 version, will that work ?

I guess I just replace platform = espressif32 ??

Trevor

Yes, you’d have to replace that line.

No Idea if Windows 7 (I hope at least 64-bit) will work, you have to try it out. You can revert to an older version anytime anyways.

HI Max,

Will not compile now …..

Resolving nodemcu-32s dependencies…
Git not found in PATH, please install Git.
Git is needed for Platform espressif32 to work.

Not seen this before

Git is a documented requirement of PIO Arduino.

Oh dear,

VSCode won’t load any of my projects now, hundreds of compile errors.

Going to start fresh with complete re-install from scratch.

So, in a few hours I’ve gone from getting on pretty well with several working ESP32 projects, to a situation now where Platformio just doesn’t work anymore.

I’ve done a complete re-install of VSCode. Even building projects that worked the other day, I get the following errors …

Any help please ?

Is this using an ancient Python version or what – that should not be happening. On the PlatformIO Core CLI, what’s the output of

pio system info

?

10

Hi Max, can’t find anything in PIO, also did a bit of Google, but still not sure how to get

“pio system info” ??

11

Hi Max, I tried to start a new project … “Project name, NodeMCU-32S, Arduino, my location. Got PIO erro box…

I’m up and running again !

A bit drastic but … I’ve gone from Win 7 to Win 10 on a new hard drive SSD, installed latest VSCode, Platformio, etc.

Might still try my old Win 7 SSD one day to see what happened.

One point, Win 10 doesn’t recognise the ESP32 as a Com port (does show up as a “device” in Device manager), but installing SP2101 drivers sorted that out.

Works OK now

Thank you Max for your time !

When interacting with an Arduino board from Python, the primary dependency is the pyserial library. This library provides the functionality to establish and manage serial communication between your Python script and the Arduino.
