Thats correct... so I have to start the conversion every time over again... and het the value after that conversion.... I have seen continuous conversions ADC on an STM32...
I will try to find a plausible solution.

Is that correct? If yes I think that is not possible because adc_receive() will refuse new data if FIFO is full.
