Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
Example 1:
referring to fig. 1, in this embodiment, the apparatus is formed by a haisi 551 board card and an RK3288 board card, the haisi 551 board card is used as a controlled board to control and drive a secondary display screen, and the RK3288 board card is used as a main control board to control and drive a main display screen. The starting display of the secondary display screen is controlled by the main display screen RK3288 main control board.
And the RK3288 board card and the Haisi 551 board card reserve two IO ports respectively in the process of hardware design to be used for communication and synchronization between the RK3288 board card and the Haisi 551 board card. The respective IO ports are defined as input ports and output ports. The output IO port of the RK3288 board card is connected with the input IO port of the Haisi 551 board card, and the input IO port of the RK3288 board card is connected with the output port of the Haisi 551 board card.

Example 2
A method for synchronously turning on and turning off a double-screen advertising machine comprises a hardware design scheme and a software design scheme, wherein the hardware design scheme comprises the device for synchronously turning on and turning off the double-screen advertising machine in the embodiment 1.
The software design scheme is as follows:
starting up the process: as shown in fig. 2, the main control board and the controlled board are powered on simultaneously, the main control board enters the boot and kernel and is initialized and connected with two IO ports of the controlled board, an output IO port of the controlled board is used for notifying the secondary display screen, an input IO port of the controlled board is used for acquiring whether the secondary display screen is in a ready state, the output IO port is set to be at a high level (i.e., set to be high) after the initialization of the main control board is completed, the monitoring is performed to the input IO port connected with the controlled board, and once the input IO port of the controlled board is acquired to be at the high level, the initialization of the secondary display screen is completed, and then the display of the boot. And similarly, after being electrified, the auxiliary display screen enters the boot and the kernel and is initialized to be connected with the two IO ports of the main control board, and the input IO port of the main control board is used for acquiring and judging whether the main control board is ready. When the output IO port of the main control board becomes high level, which indicates that the main control board has been initialized, the auxiliary display screen is set to be high at the output IO port of the controlled board, and the startup logo is displayed at the same time. At this moment, the main control board also opens the display startup logo almost at the same time, and the experience of people is that the two display screens are started simultaneously.
Standby or shutdown flow: as shown in fig. 3, when the master control board receives a standby or shutdown signal of the remote controller, the output IO port of the master control board is set low, and the controlled board detects that the output IO port of the master control board is low, the output IO port of the low connection master control board is set to tell the master control board that i is ready to shutdown, and the screen is turned off to shutdown.
