Hi All,

CEC 1.073 offers the opportunity to add up to 6 push buttons. However it is not clear to me if it is required to modify my LCD to I2C first, before I can enjoy this functionality.

You dont need to do any mods. The six resistor and buttons connect the encoder push switch.

Hi Philip,

Great! This is what I thought, but I was confused as the manual for v1072 on page 13 is saying you need to free up i/o pins before using the push buttons. Sighhhhh... software development is outpacing user manual development. The manual is very helpful though!

Ian’s explanation for the 100K is that you could add more switches later (e.g. with 51K and 27K) - but the same should work in the other direction too.?

Info is here?


Start at 15k-33k-56k-128k-220k-470k.
This will give you a good spread of ADC values, and reliable switching.
I dont know why you should start at 100k.
