Unable to build with arduino framework for CH32V003

Hi!

Thanks for the great work on this platform. I have some issues building using the arduino framework.
Installed according to https://pio-ch32v.readthedocs.io/en/latest/installation.html
Cloned the example repo and opened "blinky-arduino-ch32v003" in PIO.

Straight out of the box, I get an include error for "arduino.h".

#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (C:\Users\qdaniel\Documents\PlatformIO\Projects\ch32-pio-projects\blinky-arduino-ch32v003\src\main.cpp).C/C++(1696)
cannot open source file "pins_arduino.h" (dependency of "Arduino.h")C/C++(1696)

Tried building anyway. Got the following error:

In file included from C:\Users\qdaniel\.platformio\packages\framework-arduinoch32v003\cores\arduino\hal\wch-hal-i2c.c:1:
C:\Users\qdaniel\.platformio\packages\framework-arduinoch32v003\cores\arduino/Arduino.h:25:10: fatal error: pins_arduino.h: No such file or directory

Found "pins.arduino.h" and included it manually through build flags in platform.ini.

build_flags =
    -I"${platformio.packages_dir}/framework-arduinoch32v003/variants/CH32V003"

Tried building again and "ch32v003fun.h" was missing this time. Added it to the build flags and built again:

build_flags =
    -I"${platformio.packages_dir}/framework-arduinoch32v003/variants/CH32V003"
    -I"${platformio.packages_dir}/framework-arduinoch32v003/ch32v003fun/ch32v003fun"

No include errors anymore but seems to be a problem with the linking.

Checked "C:\Users\qdaniel.platformio\packages\framework-arduinoch32v003\cores\arduino\ch32v003fun\ch32v003fun-stack.ld:" and neither the linker script file nor the "ch32v003fun" folder exists for me. Not sure where to continue from here on.

I have tried reinstalling platform-ch32v and updating it along with PIO. Still same problem. Examples using none-os framework build and flash without any issues straight out of the box.

Ah, the "update branch" I did on the repo Community-PIO-CH32V/arduino-wch32v003@fdac06b broke it. Thanks for reporting the breakage, will fix asap.

However, there's also https://github.com/Community-PIO-CH32V/platform-ch32v/tree/develop/examples/blinky-arduino which uses the more official OpenWCH core. This one should work, but the generated binaries are a bit on the heavier side.

CI confirmed good run.

To get to a clean updated state, I would just recommend to

  1. Close VSCode
  2. Delete C:\Users\qdaniel\.platformio\packages\framework-arduinoch32v003
  3. Delete C:\Users\qdaniel\.platformio\platforms\ch32v
  4. Restart VSCode
  5. Build project again
