Hello,
There are 32 sensors in my system and each sensor is connected to one GPIO. The analog signals from sensors will be fed into PSoC, amplified and converted into digital signals. But I only want to use one set of amplifier and ADC. So that one GPIO should be selected and feed to amplifier and ADC at a time.
I know that The GPIO pins are connected to analog resources through a series of analog routing buses joined by switches and muxes. The two primary analog routing buses are the Analog Global (AG) bus and Analog Mux (AMUX) bus.
But there is no multiplier component in Creator, I'm wondering in which way I can select GPIOs. Should I implement it in program part?
Thank you so much!

There are analog multiplexer components that will do the job you want to perform. Find them in the component catalog under Analog -> Analog MUX
