Embodiment 1

[0048] see figure 1 , figure 1 It is a schematic structural diagram of a voltage-adaptable UART-to-USB system provided by the embodiment of the present application. Depend on figure 1 It can be seen that the UART-to-USB system mainly includes four parts: a UART connector 1 , a voltage determination module 2 , a UART-to-USB module 3 and a USB connector 4 which are sequentially connected.

[0049] Wherein, the UART connector 1 is connected to the UART interface on the server board, and the USB connector 4 is connected to the USB interface of the external device of the server. The voltage determination module 2 is used to determine the working voltage of the UART on the current server board, and select the current working mode of the system according to the working voltage of the UART on the current server board. The UART-to-USB module 3 converts the UART signal from the UART interface into a USB signal, or converts the USB signal from the USB interface into a UART signal.

Abstract

The invention discloses a voltage-adaptive UART-to-USB system and method. The system comprises a UART connector, a voltage determination module, a UART-to-USB module and a USB connector, all of whichare sequentially connected. The method comprises the steps that first, the working voltage of a UART on a server board card is detected; second, the working mode of the UART-to-USB system is determined according to the working voltage of the UART on the server board card; and finally conversion of a UART signal to a USB signal is performed. The system is simple in structure and can adapt to multiple different voltages, therefore, the same system can be connected with different server board cards, communicating connection between a personal computer and the server board card is more convenient,and the system is beneficial for improving user experience.

Description

technical field [0001] The present application relates to the technical field of chip design, in particular to an adaptive voltage UART-to-USB system and method. Background technique [0002] The integrated microprocessor of the server or personal computer runs parallel data inside. These parallel data cannot be directly sent from the microprocessor to external devices, but are transmitted asynchronously through UART (Universal Asynchronous Receiver Transmitter, Universal Asynchronous Receiver Transmitter) . Specifically, through the UART, the parallel data inside the microprocessor can be converted into serial data and output to an external device, and the serial data from the external device can also be converted into bytes for use by devices inside the microprocessor. UART usually exists in the form of a UART interface. The integrated microprocessor of the server motherboard and other boards of the server is equipped with a UART interface, while a USB interface is common...
