Platformio databus class definition trouble

[Deadeye5589]

Hello,

I'm trying to use Platformio under Visual Studio Code to compile a RP2040 project that works with the Arduino IDE. But with Platformio I always get an error that I don't understand

error: expected type-specifier before 'Arduino_RPiPicoSPI' 
Arduino_DataBus *bus = new Arduino_RPiPicoSPI(12 /* DC */, 13 /* CS */, 10 /* SCK */, 11 /* MOSI */, UINT8_MAX /* MISO */, spi1 /* spi */);

Any idea what Platformio wants me to do with this type of error?

If the problem only occur in platformIO but no problem in Arduino IDE, then you should ask in platformIO community.

Ok I will try, but maybe you can answer me where the define TARGET_RP2040 is normally to be set from? It does not seem to be part of this libarary. There are if conditions checking this define in the source code but non that is actually setting it.

no idea, i am not using platform io

Well, I have the anwer. It's a bug in the RPi board definition by earlephilhower. The build flag is missing in Platformio. At the moment build_flags = -DTARGET_RP2040 must be added to the platformio.ini to make a project compileable.

Found the fault in the RPi Board definition
