The LDC-HALL-HMI-EVM has different operational modes that can be changed by pushing in on the magnetic dial in the center of the EVM. In all operational modes, the magnetic dial keeps the same functionality. The angle of the dial is split into twelve segments and reported on the circular ring of LEDs at the top right of the board. Pushing in on the dial signals the EVM to switch to the next operational mode. The only change between the operational modes is how the inductive touch button data is handled.
