Very weird problem I am investigating.
Ch0 to Ch3 - everything is fine
Ch4 to Ch11 - doesn’t function
Ch12 to Ch15 - works fine, but their values are replicated to every 4th channel backwards;
For example - Ch15 high (4095 adc) will show same value (or nearly the same) for Ch11 and Ch7.
Ch14 will show same readings for Ch10 and Ch6.
Ch13 will show same readings for Ch9 and Ch5.
Ch12 will show same readings for Ch8 and Ch4.
Help is appreciated.
