HD44780 LCD Display Timeout Error

Hello,

I'm trying to connect a HD44780 LCD Display to a Pico but get the below error. I use two 4.7K resistors but maybe have connected them incorrectly (3.3-SDA,3.3-SCL)?

I'm using the native Web IDE on Windows 10.

Many thanks

I2C1.setup({scl:B6, sda:B7});
var lcd = require("HD44780").connectI2C(I2C1);
lcd.print("Hello World!");
