With power initialized, the next step is confirming the display works by printing basic text to the screen.
Implementation Guidance
– Use the TFT_eSPI library to control the display
– Make sure the display is properly initialized before attempting to write to it
– Print “Hello World” to the screen after boot to confirm the display pipeline is working end-to-end
– Experiment with text color, background color, and cursor position to get familiar with the library’s drawing functions

Recommended File Structure
power.h / power.cpp — AXP202 initialization and power rail control
display.h / display.cpp — TFT_eSPI display initialization and drawing functions
main.cpp — calls power and display initialization, then prints “Hello World”
