I m usng 29x66 chip psoc1 . i want to build an application for thermocouple k type. I am having trouble about how to route the external positive and negative analog signals of thermocouple to adc. I am confused regarding the analog section of 29x66.
I am using source meter of 1mv to 100mv to simulate the thermocouple. I used two pins to read the signal and with the help of PGA1 and PGA 2 with gain of 1 I tried to route the signals to external pins to check whether i am getting almost same voltage. i tried pushing 50mv signal but i am getting erratic results of external routed pins.
I think i am not able to route the external ground properly. I am confused and unaware about how to acheive this
