Hi,
I would like to get a Teensy Audio Board working together with LCD screen running over I2C with a Serial Converter board (https://www.amazon.co.uk/gp/product/B00K67Y4CM/).
The LCD screen needs 5v so is there anything specific I need to do to get this working properly?
I have both 5v and 3.3v on my breadboard.
At the moment I am trying to run the Teensy3.0/3.1/LC I2C Scanner sketch but I am not getting any results on the serial monitor.
I have 4.7k pullup resistors on the SDA and SCL to 3.3v and 5v going to the screen.
I have tried the lcd without the teensy audio board and am getting the same problem... so I think I am asking about 2 separate issues - 1. getting the i2c to work, and 2. getting it to work with the audio board.
Thanks for any advice or help!
