1. Introduction

The LCD driven in this article is 1.8 inches, and the controller is ST7735. It was previously ported to AT32F425, GD32L233, and CH582. This article ported it to N32L43x. Only the spi and gpio operation parts need to be ported, and the other parts remain unchanged.

Congratulations to the OP. Modular programming is indeed more efficient. However, I still suggest you restate it. After all, they are not from the same manufacturer.
