MCP960x and TCA9548A use more then one multiplexer problem

[stefan.erni]

Hi to All

If I use one 8 Channel multiplexer and record the temperatur with the appdeveloper it's working nice.
If I touch a sensor the temparetur will increase. ( Temp is temp x100)

but if I add a second 8 Channel multiplexer and increase the number of sensor to 12, all channel are wrong even the first 8channel.
As if the MCP960 is wrong config.

Ok I found what i did wrong

I have to make an additional disableAll when I have finished reading. Then it works nice.
I suppose a disable channel would also work



All 12 channel are fine
