Maybe you could propose a modification on ADC upper-half driver to enable overwriting. So, if the FIFO is full the oldest value is replaced by the new one. This could be an option on the config system.
At this moment I am working on STM32L4 ADC driver. I am implementing the low level operations, based on STM32 ADC driver. Using low level operations you don't need to use the upper-half.
