I have 2 ADC_HandlerTypeDef objects came from 2 different channel of ADC1, and I have an ADC function, like this:

ADC_read(ADC_HandlerTypeDef ADC_Handler)

How can I use this function for 2 channels?

I tried this:

if (ADC_Handler == ADC_Handler_1)

{

...

}

if (ADC_Handler == ADC_Handler_2)

{

...

}

there was compile error for "==".

This method was too heavy, since the 2 objects were different in "ADC_Channel", I want to know how to get the channel number for the ADC_Handler argument.

What about this ?

I found a solution: define 1 handler, define an array with 2 elements, update the 2 elements once ADC, then shift in 2 ADC channels for 2 elements - each one for a channel.
