Figure 5: Example of EVK-NINA-B1 target object
2.2.2.2.2 Pin mapping
Create a folder with the same name as the JSON object created in section 2.2.2.2.1. The folder should be
located in “\mbed-os\targets\TARGET_NORDIC\TARGET_NRF5\TARGET_MCU_NRF52832\”. For EVK-NINA-
B1, the folder will be called TARGET_EVK_NINA_B1.
In this new folder, there should be two files, device.h and PinNames.h.
1. device.h: This contains the
#include object.h as shown in Figure 6.
Figure 6: Example code for device.h
2.
PinNames.h: The PinNames.h file should declare and define a couple of enumerations to configure the
custom pin mapping. Figure 6 and Figure 7 show the contents of the PinNames.h file in the case of EVK-
NINA-B1.
