About LCD drive voltage
Is it possible to set the LCD drive voltage to 4.5VDC in STM32L073?
When using a VA liquid crystal panel an LCD, it is said that it cannot be driven by 3.6VDC.

The datasheet of the STM32L073, Section 6.3.21 gives some information on this: the internal LCD reference voltage can be set to a voltage between 2.6V and 3.55V.
It is not possible for the STM32L073 to generate a drive voltage of 4.5V.
Good luck!
