    ADC input multiplexing

    ashley.rodrigues

      I am using PSoc1 series Cy8c28452, I am using it to measure temperatue using a 'K' Type thermocouple. For Reference temp I am using a simple diode which is connect to Port P0.5.  the thermocuple Port pins are P0.0 and P0.1. I am using EzADC user module as I found it to be quite impressive, with offset calibration and corelated double sampling . My problem is  how do I multiplex the input of ADC between the diode (Room Temp0 and the Thermocouple output which is  thro' an Instrumention amp module.(INSAMP)
