Using Cube-generated code...
I'm a little confused about the HAL_ADC functions to read the temperature and reference voltage channels. I can read the temperature with this simple code:
HAL_ADC_Start(&hadc);
HAL_ADC_PollForConversion(&hadc, 10);
cpuTemp = HAL_ADC_GetValue(&hadc);
However, it's not clear to me how to read the reference voltage, as well. The same ''hadc'' handle is set up to read both channels. Is it as simple as calling _PollForConversion again? Or do I need to actually set up a DMA operation with a 2-field buffer.
If anybody has some sample code that does this, I'd really appreciate it.
Thanks!
