Blinky?

[AdySan]

Just got this setup according to the ReadMe. Based on the following output seems to be building and downloading ok. For a simple Blink.ino example, what PIN should I use? 13 doesnt seem to work, not sure how these nrf52 pins are mapped.

These don't work btw.

// LEDs
#define PIN_LED1                (17)
#define PIN_LED2                (18)

FWIW, the example hex files located here from SDK 11.0 work fine, so hardware is ok.

@AdySan check the back of the board, they are are actually connected to P0.17-20 which map to Arduino pin connectors D6-D9.

Yes, will test soon, wasn't sure how mappings work in this context. Will watch and learn, hopefully can contribute some day.

How do I work on the latest core? Looks like I'm not getting the latest changes from the core by placing it in hardware/nRF5 and updating it via git. I've also installed using Boards Manager. Do I need to rebuild the core somehow?
