The invention designs a method and a mechanism thereof for generating a random address code quickly and automatically, aiming at the problem that the address code must be manually changed when the production line produces a burning program, and the address code stored by the remote control in power off situation disappears. The mechanism comprises a remote controller housing, a built-in battery, areceiver, a driver, a PIC microcontroller, at least two push buttons, a flash memory, an indicator light, and a wireless transmitting circuit. The remote controller housing, the built-in battery, thereceiver, the driver, and the PIC microcontroller are electrically connected to the push buttons, the flash memory, the indicator light, and the wireless transmitting circuit. The at least two push buttons are electrically connected to the PIC microcontroller. The flash memory is electrically connected to the PIC microcontroller. The indicator light is electrically connected to the PIC microcontroller. The wireless transmitting circuit is electrically connected to the PIC microcontroller, and a built-in crystal oscillator is used for providing a clock signal to the PIC microcontroller and transmitting the wireless signal. The invention solves the problem that the address code must be manually changed when the production line produces the burning program, which improves the production efficiency, avoids the possibility of misoperation.

Method and mechanism thereof for generating random address code quickly and automatically

The invention discloses an MAC address writing method The MAC address of equipment can be stored in an NARAM at first; if the MAC address is stored in the NARAM of a host to be processed, network card connection does not need to be waited; but, after a network card is connected, the MAC address stored in the host is automatically written in the network card by utilization of a BIOS; because the MAC is stored in the NARAM in advance, a process of subsequently writing the MAC address in the network card can be automatically realized; simultaneously, a process of storing the MAC in the NARAM also can be automatically realized; therefore, the MAC address writing efficiency is increased; in addition, because the MAC address is stored in an NVRAM, after the network card is replaced, the MAC address in the NVRAM is re-written in the network card; and the MAC does not need to be burned again The embodiment of the invention further discloses an MAC address writing system, an MAC address writing device and a computer-readable storage medium, which also can realize the above technical effects

MAC address writing method, MAC address writing system, MAC address writing device and storage medium

The present application discloses a method, device and system for configuring a MAC address of an FPGA accelerator card, an accelerator card and a computer-readable storage medium. The method comprisethe following steps: receiving a MAC address configuration instruction, wherein a target MAC address is included in the MAC address configuration instruction; and writing the target MAC address intoa preset memory space according to the MAC address configuration instruction, so that an FPGA accelerator card loads the target MAC address by reading the preset memory space. This application saves the MAC address to be configured to the preset memory space, the FPGA accelerator card which needs to configure a MAC address reads the preset memory space to realize that loading of the target MAC address, that is, the present application separates the configuration of the MAC address from the loading process, eliminates the need to rely on the accelerator card-related engineering in the configuration, ensures that the recompilation of the accelerator card engineering does not affect the configuration of the MAC address, realizes the dynamic configuration of the MAC address, and facilitates the reconfiguration of the MAC address.

The present invention relates to a USB-Ethernet network card configuration method. The USB-Ethernet network card comprises a USB-Ethernet chip. The method comprises: arranging an MAC address storage area on the USB-Ethernet chip; generating a static state MAC address, wherein the static state MAC address is different from the inherent MAC address of the USB-Ethernet chip; storing the static state MAC address to the MAC address storage area and the MAC address register of the USB-Ethernet chip to take as the MAC address of the USB-Ethernet network card. The USB-Ethernet network card configuration method is configured to configure the MAC address of the USB-Ethernet network card with no need for configuration devices such as an external EEPROM chip and the like so as to facilitate saving product cost. The present invention provides a network device.

The invention discloses a method for setting IP (Internet Protocol) and MAC (Media Access Control) addresses based on an embedded system platform. The method comprises the steps of: a) selecting an idle sector from a nonvolatile memory of a target machine; s) writing an IP address and an MAC address from the selected idle sector; 3) modifying an interface function for acquiring the address in the driving layer of the target machine, and the function of the modified interface function is that the CPU (Central Processing Unit) of the target machine reads the IP address and the MAC address from the idle sector; 4) generating a target code by compiling and connecting modified codes and curing the target code in the nonvolatile memory; and 5) electrifying the target machine, initializing a network card and finishing the address set. According to the method, the technical problem that an existing method for setting the IP and MAC addresses can waste time and influence the life of large areas of the nonvolatile memory, the IP and MAC addresses of the network card of the target machine can be quickly modified, a mass of debug time can be saved, and the life of the nonvolatile memory of the target machine can be prolonged.
