SPI Explained - ESP 32 - 57,600 Pixels Only5Pins -- Electronics Explained Fast #4

In this video we break down how a tiny 1.28‑inch round TFT IPS display with 57,600 RGB pixels can run from just 5 microcontroller pins. We compare it to a classic four‑digit seven‑segment display that needs 12 pins just to drive 32 LEDs.

The secret is the display’s built‑in driver chip and the high‑speed Serial Peripheral Interface, which handles commands, pixel data, and timing. We walk through each pin—SCL, MOSI, DC, CS, and RST—explain what they do, and show how powering VCC also turns on the backlight.

Then we show how easy it is to initialise the driver in code and start pushing pixels for text, icons, gauges, and more.

This tiny round IPS screen delivers bright, smooth graphics with only a handful of wires. And in the next video, we’ll explain why a 0.96‑inch OLED only needs two GPIO pins.
