NFCEMU for solosky

Overview

Use ATMEGA328p microcontroller to realize the functions of NTAG215. Power supply mode 1: button battery power supply; mode 2: USB direct power supply.
Note that you need to use USB ISP to burn boot.
The programming software is progisp2.0. First, modify the programming fuse bit to the low value: 0xCE, the high value: 0xDE, the extension bit: 0xFF, and then save it;
then program the optiboot_flash, and only check the chip erase and program FLASH during the process. After burning, uncheck the chip erase and then burn firmware.hex;
refer to the attachment for the bill of materials and firmware, and refer to the production process https://www.bilibili.com/video/BV1SN4y1K7Un/
Finally, thank you to solosky for your guidance!

Can someone explain GAPI to me?
For example, the display driver in BSP supports GDI and DDRAW, and supports hardware 2D acceleration. Does GAPI bypass the display driver layer to directly operate the framebuffer? Does GAPI implement
