sdkconfig for multiple projects with common code components
Posted: Thu Jun 27, 2024 7:37 am
I have roughly this setup.
The common_code folder contains various hardware drivers that are used by both Project_1 and Project_2. However, the GPIO configurations and some other parameters are different. The Kconfig in each component folder contains a “default” configuration.
This is an example of the Kconfig for the accelerometer component.
I had hoped to be able to open the sdkconfig in each project in the sdkconfig editor (Espressif IDE) and configure the specific settings.
However, when I build the project, the sdkconfig settings are overwritten by the Kconfig settings.
I could, of course, have a sdkconfig.default or so in each Project folder, but that would require this to be created/copied manually and
if a new setting is added to a component, all projects needs to have their sdkconfig.default files updated manually.
As it is now, it looks smooth, the component setting show up in sdkconfig. But sadly, it doesn’t work, as I cannot change the config, per project.
Any ideas how to accomplish this?
Did I miss something?
