Adaptive speed single-wire communications

A device comprising:

• an interface configured to couple to a single-wire bus and receive a communications signal from a second device through the single-wire bus;
• a receiver configured to receive a sensing signal from the second device through the single-wire bus and analyze one or more properties of the sensing signal, the one or more properties including at least one of a pulse width of the sensing signal and a duration between sequential pulses in the sensing signal;
• an adjustment circuit configured to adjust one or more communication parameters for communication with the second device based on the analyzed one or more properties of the sensing signal;
• and
• a transmitter configured to transmit a specific signal to the second device through the single-wire bus at an adjusted transmission speed based on the adjusted one or more communication parameters.

A non-transitory, computer-readable storage medium configured to store instructions, which, when executed by one or more processors, causes the one or more processors to perform operations comprising:

• receiving a sensing signal from a device through a single-wire bus;
• analyzing one or more properties of the received sensing signal, the one or more properties including at least one of a pulse width of the sensing signal and a duration between sequential pulses in the sensing signal;
• adjusting one or more communication parameters for single-wire communications with the device based on the analyzed one or more properties;
• and
• transmitting a specific signal to the device through the single-wire bus at an adjusted transmission speed based on the adjusted one or more communication parameters.
