+# Raspberry Pi Pico + LCD
+
+MicroPython setup, wiring, drivers, and test scripts
+
+## 1. Install MicroPython on Raspberry Pi Pico
+
+1. Download the MicroPython UF2 for Pico:  
+   [https://micropython.org/download/rp2-pico](https://micropython.org/download/rp2-pico)
+2. Hold **BOOTSEL** while plugging in the Pico.
+3. Drag the `.uf2` file onto the Pico drive.
+4. Pico reboots into MicroPython.
+
+---
+
+## 2. Using Raspberry Pi Pico in Visual Studio Code (MicroPython)
+
+### Steps
+
+1. Connect Pico via USB
+2. Open Visual Studio Code
+3. Press **Ctrl + Shift + P**
+4. Select **Pico: Configure Project**
+5. Choose the correct COM port
+6. Open REPL
+7. Upload your `.py` files to the Pico
+8. Run scripts directly from Visual Studio Code or REPL
+
+---
+
+## 3. Wiring (Pico → LCD + Touch)

+## 4. Drivers
+
+### ILI9341 Display Driver
+
+Save as: **`ili9341.py`**
+
+**Source link:**  
+ [https://github.com/rdagger/micropython-ili9341](https://github.com/rdagger/micropython-ili9341)
+
+---
+
+### FT6336U Touch Driver
+
+Save as: **`uFT6336U.py`**
+
+**Source link:**  
+ [https://github.com/fantasticdonkey/uFT6336U](https://github.com/fantasticdonkey/uFT6336U)
+
+---
+
+## 5. Test Code
+
+1. Run **`demo_setup.bat`** from the `demos` folder to download the driver files.
+2. Connect the Pico to Visual Studio Code and upload **`ili9341.py`** and **`uFT6336U.py`** to the Pico.
+3. To test the LCD, open **`shapes_demo.py`**, upload it to the Pico, and run the current file. The display should show colored lines, rectangles, polygons, circles, and ellipses.
+4. To test the touchscreen, open **`touch_demo.py`**, upload it to the Pico, and run the current file. Touch coordinates should appear in the Visual Studio Code REPL.
