Abstract
The utility model relates to a tobacco purchasing information screen which is characterized in that a microcontroller is included, the microcontroller is connected with a storage and a plurality of displaying modules, adjacent displaying modules are connected in series, the storage is a flash storage, and the storage is connected with the microcontroller through an SPI bus system. The tobacco purchasing information screen has the advantages that the displaying modules are connected in series, the microcontroller controls the independent displaying modules for displaying, the flash storage has nonvolatile performance, is large in storing capacity and can store various displaying codes conveniently.
Description
Technical field
The utility model relates to a kind of information screen, is meant a kind of tobacco purchasing information screen especially.
Background technology
The existing information screen that is used for tobacco purchasing extensively applies to the place of tobacco purchasing flow process, for which kind of flow process the tobacco leaf that allows the seller can understand oneself clear, rapidly is in, its importance is self-evident, and existing information screen adopts the demonstration of single display module substantially, and each display module all needs controller control one to one, cause the waste of resource, display window is less, and each display module can not independent displaying.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of display module more and tobacco purchasing information screen that can independent displaying.
The technical solution of the utility model is achieved in that a kind of tobacco purchasing information screen, it is characterized in that: comprise microcontroller, be connected with storer and several display modules on this microcontroller, adjacent display module adopts series system to connect, described storer adopts the flash storer, and described storer adopts the spi bus system to be connected with microcontroller.
By adopting technique scheme, each display module adopts serial connection, each independent displaying module of microprocessor controls shows, that flash storer wherein has is non-volatile, memory capacity is big, be convenient to store various code displaying, the spi bus system can be directly and the multiple standards peripheral components direct interface of each manufacturer production, and the usability height is convenient to promote.
The utility model further is set to: described microcontroller also is connected with host computer, and microcontroller is realized data transmission by UART unit and host computer.
By adopting technique scheme, reception data and the transmission data of using the UART unit to realize that data transmission can be separate are supported synchronously and asynchronous operation.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the theory diagram of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model discloses a kind of tobacco purchasing information screen, in the utility model specific embodiment, comprise microcontroller 1, be connected with storer 3 and several display modules 4 on this microcontroller 1, adjacent display module 4 adopts series system to connect, described storer 3 adopts the flash storer, described storer 3 adopts the spi bus system to be connected with microcontroller 1, wherein, the spi bus system is a kind of synchronous serial Peripheral Interface, it can make MCU and various peripherals communicate with exchange message with serial mode, and each shows mould, and 4 adopt serial connection, microcontroller 1 each independent displaying module 4 of control shows, flash storer wherein has non-volatile, memory capacity is big, is convenient to store various code displaying, and the spi bus system can be directly and the multiple standards peripheral components direct interface of each manufacturer production, the usability height is convenient to promote.
Wherein, adopt the mode of serial connection to connect between each display module 4, promptly each display module 4 joins end to end, and each display module circuit structure is identical.Can increase and decrease what of display module as required, each display module has promptly been determined explicit address according to the position that it connected, and is convenient to software in the required content of definite position display.
In the utility model specific embodiment, described microcontroller 1 also is connected with host computer 2, and microcontroller 1 is realized data transmission by UART unit and host computer 2, reception data and the transmission data of using the UART unit to realize that data transmission can be separate are supported synchronously and asynchronous operation.Wherein, UART is a full duplex universal synchronous/asynchronous serial transceiver module, and this interface is the serial communication device of a high flexible.
The software design of microprocessor is introduced embedded real-time operating system μ C/OS-II, the groundwork of μ C/OS-II operating system nucleus is that task (task) is managed and dispatches, the whole application system program is decomposed into a plurality of little tasks, the a plurality of tasks of system's concurrent running, thereby improve the utilization factor of processor, the execution speed of faster procedure, the real-time response of raising system.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
