Error: #error directive: "CMSIS Target not recognised" in "extras/mbed/cmsis.h", Line: 16, Col: 3

Hi!

I am quite new to this forum - I bought a Blue Pill based board...which seems to be emualting the Nucleo FB103RB board.

I saw the midiusb example in this forums cookbook - USBMIDI - Hello World and did compile it.

This code seems to be quite old - if updating the mbed class...a lot of errors shows up. If going back to an older version...most errors disapper.

However one error still remains - which makes it impossible to generate a execution bin file:

Error: #error directive: "CMSIS Target not recognised" in "extras/mbed/cmsis.h", Line: 16, Col: 3

The recommendation is in case to update everything...however this does not work at all and the error still remains...

Any great ideas are welcome.. I can't imagine that the USBMIDI support does not work any more for MBED Code......(or Is it this Nucleo board which is old...)

Best Regards

Anders

Hello Anders,

The code you are trying to compile seems to be outdated. The latest version would be:

https://os.mbed.com/users/samux/code/USBMIDI_HelloWorld/

However, I believe that code only works for the LPC1768, LPC11U24, FRDM-KL25Z. For the Nucleo-F103RB, I would recommend looking at this library:

Hope this helps!

Hi!

Sorry for a late reply - but You are right. Using the right library actually made the gode to complete without any errors.

I have now implemented the code on my blue pill board and it seems like it is executing on the platform. I have problems to get the internal USB port on the board to communicate....but I am guessing I need to connect a external USB connection to make it to fly.

Best regards

Anders
