Steps to Reproduce

1. create a new project. (BBC Microbit board, MBed framework)
2. add "lib_deps = microbit-dal" to platformio.ini
3. add "#include "MicroBitDisplay.h" to main.cpp (or any other microbit-dal header)

Actual Results

Expected Results

Successful compilation

If problems with PlatformIO Build System:

The content of platformio.ini:

[env:bbcmicrobit]
platform = nordicnrf51
board = bbcmicrobit
framework = mbed
lib_deps = microbit-dal

Source file to reproduce issue:

#include <mbed.h>
#include "MicroBitDisplay.h"

int main() {
  while(1) {
  }
}

Additional info

The microbit-dal library hasn't changed. It is still available in the registry. On my machine It is listed as installed in "PIO Home" along with "ble" and "ble-nrf51822"
I get the same behaviour from PIO on macOS (10.15.2)

I have exactly the same problem with a project with the ble" and "ble-nrf51822" libraries.
I would really need a solution, it stopped compiling with release 4.2.0 onward.
Before it was OK

Hey, I wonder if this will help you. I got it working for a Red Bear Nano v1, which uses the nRF51822 https://github.com/knud/RB_Nano_v1 steven On February 25, 2020 at 07:47:51, franzle (notifications@github.com) wrote: I have exactly the same problem with a project with the ble" and "ble-nrf51822" libraries.

Thanks for the report!

1. Upgrade PIO Core to the latest development version via pio upgrade --dev
2. Please remove .pio folder from a project
3. Start buidling project.

Does it work now?
2. re-run
