I’ve just started with Platform IO in Visual Studio Code, using the mbed framework and a STM32F103C board, and I’ve successfully compiled and uploaded a blink app via a ST-LINK clone. However, Visual Studio Code shows a compile error:
'mbed.h' file not found (1, 10)
Even though the app works, it’s quite distracting to have this spurious error highlighted in the Problems view and as red squiggly lines in the code. So what could be wrong with my installation?
The error occurs with every include file from the platformio directory, not just mbed.h
.
mbed.h
exists in /Users/abc/.platformio/packages/framework-mbed
and the directory is the first entry in the includePath section of c_cpp_properties.json
. Strangely enough, IntelliSense even propose mbed.h
if I type #include "mb
.
I probably need to mention that I’m using macOS High Sierra, the latest Visual Studio Code (1.27.2), PlatformIO 3.6.1a4. And I have used Visual Studio Code before for other, non-PlatformIO C/C++ projects.
The app code is as simple as it gets:
main.cpp
#include "mbed.h"
DigitalOut myled(PB_12);
int main()
{
while(1)
{
myled = 1;
wait(1.0);
myled = 0;
wait(0.2);
}
}
