I have a 6 input analog multiplexer connected to a 12Bit SAR ADC on a PSoC5LP. I want to connect one of the Mux inputs to the internal analog ground of the PSoC5LP in order to get a 0V offset reading through the Mux. How can I achieve this.
I know I can use a pin connected to 0V on the outside, but the PCB is already made, so it is not an option.
Any suggestions how such a routing can be achieved will be welcome.
Best regards
Chris

Hi Odissey1
I should kick myself. I dragged the 1.024V ref in as I could not find anything else for Analog, but I never went into the properties!!
Thanks for your assistance.
Regards
Chris
