Problems solved by technology
The USB data transmission line and the UART data transmission line in the prior art are all set separately. When detecting whether the UART transmission line is normal, it is necessary to pass the hardware bonding wire from the UART signal end (such as the data sending end and the data receiving end) on the motherboard. It is connected to the UART interface in the same way, and the terminal equipment needs to be disassembled when welding the wires. The operation is complicated and cumbersome, and requires professionals to operate. It not only takes a lot of time and labor costs, but also easily damages the equipment.

The invention relates to the field of terminal technology and discloses terminal equipment and a connector control method and device. The connector control device comprises a charging chip, a USB interface, a channel switching chip, a processor, a power management chip and a resistor; a voltage pin of the USB interface is connected to the input end of the charging chip, and the output end of the charging chip is connected to a first interrupt pin of the processor through the power management chip; the USB interface is connected to the processor through the channel switching chip; one end of the resistor is connected to a second interrupt pin of a UART signal end, and the other end of the resistor is grounded. The embodiment of the invention furthermore provides the connector control method and the terminal equipment. Compared with the prior art, the USB interface can be used to realize detection of a UART signal line, it is not needed to perform disassembling for hardware wire bonding, operation is simple, and it is beneficial for protecting equipment safety.
Description
technical field [0001] The present invention relates to the field of terminal technology, in particular to terminal equipment, a connector control method and device. Background technique [0002] The current terminal equipment generally has a USB interface and a Universal Asynchronous Receiver / Transmitter (Universal Asynchronous Receiver / Transmitter), which is usually called a UART. The USB data transmission line and the UART data transmission line in the prior art are all set separately. When detecting whether the UART transmission line is normal, it is necessary to pass the hardware bonding wire from the UART signal end (such as the data sending end and the data receiving end) on the motherboard. It is connected to the UART interface in the same way, and the terminal equipment needs to be disassembled when welding the wires. The operation is complicated and cumbersome, requiring professionals to operate, which not only takes a lot of time and labor costs, but also easily d...
