STM32F103RGT6 - Confusion about adc pins

[fifi_22]

Hello.

I want to use ADC in my STM32F103RGT6 Uc, but I don't understand what pdf's says about where the pins are.

In this document We can see, that there are 3 ADC converters: ADC1, ADC2, ADC3.

However, reading further on page 29, I can see alternate functions for ADC3 for example on pins PF6-PF10. But then PC0 and PC1 is somehow ADC123_INXX. What does this mean? I also cannot find any pins with ADC0_INXX or ADC1_INXX alternate function... Are they somehow multiplexed?

Thanks for advice!

ADC123_INXX is shorthand for ADC1_INXX, ADC2_INXX and ADC3_INXX. It can be used for any of the 3 ADCs. It's confusing until you know what it means.
