Feature request: LDF scan for a new entry "mcu"
- [x] Feature Request. Start by telling us what problem you’re trying to solve. Often a solution already exists! Don’t send pull requests to implement new features without first getting our support. Sometimes we leave features out on purpose to keep the project small.
Configuration
Operating system: All
PlatformIO Version (platformio --version): latest development
Description of problem
Add a option to the LDF to scan for mcu in librarary.properties or in library.json
mcu is already a entry in Arduino ESP32 boards.txt
Esp32 has different mcu cores now (ESP32-C3 soon too) which needs different libraries.
At the moment there is no possibility to differentiate this or did i missed something?
Maybe as new command strict+ ?
It should be implemented in dev-platform. See https://github.com/espressif/arduino-esp32/blob/master/tools/platformio-build.py#L177
HI @Jason2866 ! Could you please provide an example of any library that needs this feature?
Hi @valeros
The ESPP3232-C3 is available. All libs which are compatible to core esp32 are used for the C3 too, as there is no possibility to handle the mcu variant with LDF.
We have some optimized libs which are mcu dependent ( xtensa vs. riscv) it would be nice not to litter the code
with many #ifdefs to take care of this. More elegant would be to have lib variants for every architecture
