I am using PSoC4  CY8C4247AZI-M485 to measure 8 currents and i also want to measure a thermistor.  I can not seem to get PSoC to build this is there another way I can do this?

The Creator routing engine does not like single pin signals routed to two mux inputs. It "should" work but it doesn't
So, make two VT pin inputs, one for the low side of Vhi, and the other for the high side of Vlow. I had to do it
this way for a multiple thermistor scanner; it works.

Hi,

Could you please connect different pins to 8 and 9 channel for VT terminal and see if the routing is passing. PSoC will not have adequate routing resources to do the routing you have requested for.

Best Regards,

Hi,

Additionally check the following appnote for thermistor measurement examples.
