Why NUCLEO-H753 ADC channel 12 is missing in CubeMX

Hi,

    Why NUCLEO-H753ZI ADC channel 12 is missing in CubeMX ?

     ADC channel 12 is in NUCLEO-H753ZI board CN9-9 connector.

     A few other ADC channels are also missing in CubeMX.

    Thanks,

How did you determine that CN9-9 is channel 12?

 

I was told that if a devices starts to smoke, put the smoke back in. I guess I never got all the smoke because the device never worked afterwards.
Don't worry, I won't byte.

In NUCLEO-H753ZI  schematics -    PC3 is connected to CN9-9, which is Channel 12 for ADC1, ADC2 - in the H753 users manual 

Well CN9-9 is PC2 not PC3.

The document clearly shows that only the TFBGA240 +25 package supports channel 12.

The Nucleo board has LQFP144 package.

CN9-9 is called "PC3" in the schematic, which is misleading, but it's actually the PC3_C pin, not the PC3 pin. That is the reason ADC1_CH12 is not available--because the chip doesn't have a PC3 pin.

"Well CN9-9 is PC2 not PC3." - Yes, PC2 is in CN9-9 according to the the schematics, , which is misleading as TDK replied. Thanks

Thanks

Ok, so you're mislead to believe it was PC2. But where in the users manual did you find PC2 has channel 12?
