Wave 1.28 inch IPS Round LCD Display SPI

This is a 1.28” LCD Display Module with an input voltage of 3.3V ~ 5.5V, which is used to display colorful patterns and characters. The driver used in this LCD is GC9A01, with a resolution of 240RGB×240 dots and 129600 bytes of GRAM inside. This LCD supports 12-bits/16-bits/18-bits data bus by MCU interface, which are RGB444, RGB565, RGB666. This LCD uses a 4-line SPI interface for reducing the GPIOs used. If you are wondering which point is the first pixel of the screen (because the screen is round), you can understand it as a square screen with an inscribed circle drawn in it, and it only displays the content in this inscribed circle. The pixels in other locations are simply discarded (just like most round smartwatches on the market).
