  • 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!");
