Congratulations to the update and the new features!
I tried to install support for the “Blue Pill”-Board (STM32F103C) by adding http://dan.drown.org/stm32duino/package_STM32duino_index.json to the packages folder.
The board (Generic STM32F103C series) is shown in the device list.
After clicking on “download & install” the following error message appears:
Installing Arduino dependencies… Error: package stm32duino not found Could not determine platform dependencies
C:\Program Files\XOD IDE\resources\arduino-cli.exe --config-file=C:\Users\OPTIPL~1\AppData\Local\Temp\arduino-cliqTbLxj\.cli-config.yml core install stm32duino:STM32F1
failed with code 4
How can I fix this?
