Setup : I am trying to interface an E Paper Display with the nrf52832 chip.
The issue is that I have a EPD.lib file and an EPD.h which includes the methods to drive the E Paper Display. I've imported both the .h and the .lib file in the project, but I'm still unable to use the methods defined in the .h file. Is there a way this can be done using the .lib file or do I need to change it to some other format like .a?
Below is the code in my EPD.h file

* @brief Module for generating a pulse-width modulated output signal.
*
* @details This module provides a PWM implementation using timers, GPIOTE, and PPI.
*
* Resource usage:
* - 2 PPI channels per instance + 2 PPI channels per PWM channel.
* - 1 PPI group per instance.
* - 1 GPIOTE channel per PWM channel.
*
* For example, a PWM instance with two channels will consume 2+4 PPI channels, 1 PPI group, and 2 GPIOTE channels.
*
* The maximum number of PWM channels per instance is 2.
