Using pioasm in platformio projects

Here is somethig you might find useful: automatic pio assembly -> h file generation for platformio.
I have tested it on Linux only.

This is the state as of Nov 2022. The arduino core for RP2040 will most likely change in the future and make this method obsolete.

May 2025 Update.

The pioasm tool by earlephilhower has been removed from the official Platformio repository, thus installing it requires choosing the correct version (OS) from the releases and providing a direct link to the package.

Step 1:

Visit the tool release page:

* Not the most flash-wise efficient way, but convinient.

Trick to avoid sdcc (not supported keywords) errors in VScode
#ifndef _VSCODE_SDCC_H
#define _VSCODE_SDCC_H
/*
There is currently no support for sdcc syntax (Intellisense) in VScode.
These defines will limit the number of reported errors due to undecognized
sdcc keywords like __code, __at etc.
The trick is, when editing the code in VScode, the SDCC is not defined,
it happens only at compile time. So we can use the "#ifndef SDCC" condition
to redefine the sdcc keywords as empty and make the errors go away.
When compiling, the SDCC is defined and the below redefinitions will not be
