Program Description
After this API is executed, a user-defined communication packet will be
transmitted.
Refer to the Communication Principle Description for the packet formats in detail.
The following table lists each API used by the charging base.
Command Name Functional Description
Demodulation Parse the communication data and confirm whether the toothbrush body ID is
consistent with the charging base ID
OCP_demo_trim Automatically calibrate the decoding level
PWM_ping_cycle Transmit control subroutine
time_init Timer initialisation
OCP_CAL OCP comparator circuit offset calibration
DELAY_10us 10µs delay subroutine
