Platformio uses standard release packages and tools No need for custom littlefs script Remove pressure sensor noise variance user configuration (KF3 algorithm vestigial option for shaping overall response) Reorder partitions, littlefs now has 190kBytes available
This is the last release containing a build option for the KF3 algorithm, and some test code to dump sensor noise statistics. Future releases will only use the KF4 algorithm.
With the changes in Arduino component for ESP-IDF and changes in ESP-IDF, it's become difficult to get a combination of the two that will work together without compile errors. For example, my version of the Arduino respository did not compile with ESP-IF v 3.2.2 for me. And since I didn't upload the Arduino component files here (too many), it would be difficult :-) for anyone downloading the code to make it even compile.
So I decided to just tag this version for archival
v0.9 onwards will have the required Arduino component files included in this repository and will be associated with a specific ESP-IDF release e.g. v3.2.2
