+==== Test Code ====
+\\
+We need two files to be able to test this project.
+  * 1. The Driver for the LCD.
+  * 2. A test Python script to write to the LCD.
+We need to put the driver in the lib folder on the Pico. If you don't have a lib folder you need to create one.
+\\
+\\
+{{ :lib-driver-test-text-2.4-lcd.png?300 |}}
+\\
+Above we can see the Pico drive, and there is a folder 'lib' with the driver st7789.py, then in the top level folder there is a test file called text-text-examply.py
+\\
+\\
+<color #ed1c24>**Please note, there has been some improvements in the driver since this page was started, the driver is now called st7789nf.py not st7789.py.**</color>
+\\
+  * You can download the driver {{ :st7789nf.zip |Here.}}
+  * You can download the test Python file {{ :screen-test.zip |Here.}}
+Once these are both saved to your Pico, you can open the test file in Thonny.
+\\
+\\
+{{ :thonny-test-python-run.png?700 |}}
+\\
+Now click the green play button, top left in Thonny, and the code should execute with zero errors.
+\\
+\\
+If you have wired your LCD up correctly, and have placed the driver and the test script in the right place, then you should see something similar to below.
+\\
+\\
+{{ :lcd-8-line-test-2.4-240-320-tenstar.jpeg?300 |}}
+\\
+Now you are ready to tackle any project on this wiki, or indeed your own project, that requires a nice LED.
