Hi All,
Be aware on the projects where I have used an I2C LCD I get a burst of noise in the receiver at display-update-time. While
the display is not being updated, the noise is low enough that 0.1 uV signals can be copied.
I suggest it would be worthwhile to use one of the freed-up digital pins to control an audio mute during the display update period.
