Hi gurus,

I am finding trouble with psoc1 in connecting the external analog ground with the physical ground of psoc. how to do this? I tried many things but i am missing something and am confused. I have used psoc creator but psoc designer is somewhat confusing to me mostly the anlog section. Please help

I want to connect the analog sensor to pin 0_2 and pin 0_3 where p0_3 in positive and p0_2 is negative(ground) respectively. I just dont know or i am uncapable of routing the external ground this leads to erratic result of adcinc.

I request you to kindly refer to AN2219 - PSoC® 1 Selecting Analog Ground and Reference.

Since our PSoC1 family is mature, and very little support is available, I request you to kindly consider our newest PSoC4 and PSoC6 families for your new designs.

Best regards,

Sampath Selvaraj
