@@ -56,4 +56,14 @@ To clear the screen for new text you can use the following code:
```cpp ```cpp
tft.fillScreen(0x0000); //clear the screen tft.fillScreen(0x0000); //clear the screen
``` ```
## Wiring
You can connect the wires to any pin except the vcc and the ground. The vcc and ground need to be connected to the 3.3v and ground of the esp32. The other pins can be connected to any pin of the esp32.
