Hi,
Does anyone know about an LCD display with keypads using I2C.
Meaning that also the keypresses are communicated though I2C ?
Or if that isn't available, can someone suggest a separate 4-10 keypad that can be connected as i2c. And less polling the better..
There are some i2c backpacks that you can buy that support a LCD and a keypad.
ByVac makes a couple and you can find them on Ebay as well.

For the keypad have you considered using an IR remote?
