HD44780 LCD Display Timeout Error

I just tried it out on my pico (pardon the contrast, but the Hello World is there)

However, I could only get it to work with I2C2

If I use I2C1 b6/b7 I get this error:

Uncaught InternalError: Timeout on I2C Write Transmit Mode 2

                              ^
Execution Interrupted

Here's the code I used to test with I2C2:

I2C2.setup({scl:B10, sda:B3});
var lcd = require("HD44780").connectI2C(I2C2);
lcd.print("Hello World!");
