I installed BSP_DISCO_F746NG, all dependency errors are resolved but one 1 header file

I am migrating to platformio, so I guess I missed something…

After I installed the BSP_DISCO_F746NG library all dependency errors are resolved but one:
cannot open source file “stm32746g_discovery_lcd.h”

My platformio.ini

platform = ststm32 
board = disco_f746ng
framework = mbed
lib_deps =

In main.ccp
#include <mbed.h>
#include “LCD_DISCO_F746NG.h”
#include “TS_DISCO_F746NG.h”

Does the project compile and this is just a VSCode Intellisense error? The header is definitely in the BSP_DISCO_F76NG library.


Also listed as a header in the PlatformIO library

If it’s a compilation error, can you show the full error message?

No it’s not just Intellisense . It really does not build:

Yesterday I’ve had a similar issue with BSP_DISCO_F769. @maxgerhardt, you’re post in another thread here pointed me in the right direction (thanks!): the library.json of that library does not include the “build” section, where the additional include search paths are specified. Manually adding the lines you’ve suggested (adapted for the actual devices present on the 769NI) did the trick, my project compiles now.

Maybe this helps, here, too?

Since I’m quite new to using platformio, this may be a silly question: where could one suggest a change of the library.json? Submit an issue against platformio-libmirror, since the file is probably autogenerated from ST’s mbed sources?
