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)
.

There is an AMUX component that could perform what you need, it would be very helpful for us (saving time) when you post your complete project here. To do so, use Designer -> File -> Archive Project (minimal) and attach the resulting file here.
