Resonant frequency monitoring
L^C BOOT 72.6 KHz The first-time measured resonant frequency after
powering on for the circuit board of the power
supply port
New PEAK 67.8 The latest measured resonant frequency, the unit is
KHz
/4120 The period timer value in the internal IC of the
latest measured resonant frequency
Hi 69.3 Under the system set wireless power transmission,
the highest resonant frequency
Lo 66.1 Under the system set wireless power transmission,
the lowest resonant frequency
alignment 45% The current measured resonant frequency
Equal to the value of Lo, which shows that the coil
between RX and TX is the closest, the calculated
value is 99% , Equal to the value of Hi, which
shows that the coil between RX and TX is the
farthest, the calculated value is 0% , No wireless
power transmission will be conducted over this scope
PWMout/ 91.8 Driver output frequency
