IP address based on the MAC address. Router Query MethodIf you have the permission to log on to a vro (such as a home network), you can directly query the IP address assigned by the vro to the access control card on the vro management interface. 2.2 front-end controller card reading display and uploading Log on to the front-end access control panel. The IP address of the access control panel is the IP address (192.168.20.106 in this example) found i

Look at build 2015 in the middle of the night, basically heard 3, 4 times "Raspberry Pi", but always did not demonstrate win10 in the RPI above what kind of, so ... Try it yourself. First the pit is DISM: see an Ffu file, read the instructions, that is DISM directly deployed to the SD card. So is it possible to use LINUX+DD? Try it, no ... Then using win8.1 for DISM, found error 87, go back to look at the

Gpio Library core function, of course, is the operation of Gpio, Gpio is the "general input/Output" interface, such as lighting a LED, relays, or through the IIC SPI 1-wire and other protocols, read, write data, this is the use of Gpio, can say no gpio, Raspberry Pi can only be used as a small computer, with a gpio, it is upgraded to a controller. First of all, h

to scan the register for the interrupt number of the interrupt, and call the corresponding callback function if the interrupt occurs.1.for_each_set_bit (i, EDSR, + ) //cycle to find a bit in the EDSR that is 1 is interrupted 2.Generic_handle_irq (Gpio_to_irq (GPIO));//interrupt callback function that calls the interrupt vector (will be filled in when the driver requests an IRQ resource) GPIO_TO_IRQ (GPIO) is the interrupt vector number where the interrupt occurredThree • Interrupt
