How to assign another GPIO for ADC on PSoC63

[GaryLim]

In the basic ADC example (clean example from New Application), how can I change the default GPIO from P10_0 as defined by VPLUS_CHANNEL_0 to another GPIO? 

#define VPLUS_CHANNEL_0 (P10_0)

When I tried to reassign the GPIO for example to P9_2, the error message below is shown.

-----------------------------------------------------------
HAL: ADC using HAL
-----------------------------------------------------------

ADC initialization failed. Error: 67240192

In the Device Configurator, there is no initialization of P10_0 for the ADC. Is this hard coded somewhere?

Thanks

Hi @GaryLim ,

You should use analog pins rather than the GPIO pins. please try with Port10 pins i.e. from P10.0 to P10.7.
