Why does UART need FIFO? Modern CPUs run faster and faster. UART usually has a baud rate of less than 10 M. In the absence of FIFO, CPU time is consumed for each data filling to or from UART, this is a great waste. Therefore, the UART is configured with FIFO as the buffer for data sending and receiving on the hardware. Each time the CPU needs to fill in the data, it will fill in the uart tx fifo. Each time the CPU needs to get the data, the data will be retrieved from the uart

devices will have a total of 4 working states: Sleep (sleep mode): The node shuts down the send and receive modules for hibernation, thus minimizing energy consumption. Rx Idle (Receiving idle state): The node listens to the channel but does not actually receive the data frame. Rx (Receive status): The node hears the data frame and receives it. Tx (send status): The node sends a data f

connects the Docker container on one host to a virtual network bridge. The following highlights this pattern.Host mode Use –net=host to specify when using Docker runThe network used by Docker is actually the same as the host, and the IP card that is seen in the container is the IP on the host.

So we sort the $x$, $y $ coordinates and find their prefixes and can.We then enumerate each point to find the answer in this point meaning and update the minimum value of the
