Hi Suraj,
Embedded Wizard is based on some functions from NXP’s hardware abstraction layer which is an essential part of the NXP SDK (files starting with “fsl_”). This is an common method in modern MCU development, cause low level driver development take a lot of effort and is already done by NXP.
In some case, transferring information to the display, we do not use the predefined graphic writing methods.
Best regards,
Tim
