Maybe you need more ADC chips . I dont know how to use gpio as as analog reading , As I understand , GPIO only get 2 level input 1 or 0 , and if your analog signal over 2 levels ,how to measure ? Another idea is use TDM switcher , maybe you can find some chip can do switch several ADC input and 1 or more digital output . I dont know if there is this kind of chip ,maybe
