LCD I2C Direct Connection #4

Hi Alan. I am trying to build your Music-Streaming-Box and wish to connect a 16x2 LCD display with I2C interface directly to the SDA and SCL terminals on the Pi. However, having followed your instructions I am unable to get any data to the display. Am I doing something wrong? regards

Bryan Allen

Hello Bryan, the code in this repo is for this specific LCD display: https://www.adafruit.com/product/181 and that uses SPI instead of I2C. So if you want to use I2C it is possible but you would have to use a different library and change the code accordingly. What model display are you using?

Hi Alan. It’s an HD44780 compatible display.BryanOn 22 May 2024, at 03:33, Alan Boris @.***> wrote: Hello Bryan, the code in this repo is for this specific LCD display: https://www.adafruit.com/product/181 and that uses SPI instead of I2C.

If your display already has I2C and you want to connect using that method, then you'll need to modify the code a bit to work with the particular library for your display. Alternatively, you might be able to attach a backpack like this: https://www.adafruit.com/product/292 and connect to the Pi via SPI so the code works as written.

Okay, thanks for your help, Alan. I will have a look and, hopefully, get it working.Regards BryanOn 24 May 2024, at 04:44, Alan Boris @.***> wrote: If your display already has I2C and you want to connect using that method, then you'll need to modify the code a bit to work with the particular library for your display.
