If my board does not have a PN7150 module embedded, can I use an external module having a PN7150 embedded?

Yes, it is possible. You must have in mind:

• Assure that the external module you are using is a functional one.
• Set the I2C address for your external module (hardware configuration. For more information go to PN7150 User Manual page 19). Then, you must define the physical address for PN7150_ADDR in your code.
• Identify the SDA and SCL pins in your host (MCU) and in your external PN7150 module to wire them with each other.
• Assign two GPIO pins to your MCU to work as IRQ and VEN. You must declare them as the physical pin number in PN7150_IRQ and PN7150_VEN, respectively to enable them when the execution requires it. You must identify the IRQ and VEN pins in your external PN7150 module to wire them to the respective pins in your MCU.

Is it possible to use the NDEF Tag Emulation?

The example of NDEF is still in the review process. In order to know the status and the latest actualizations, you can check the Pull Request here.

My question is not here 😶‍🌫️, or I would like to contribute to this library!
