The invention discloses a multi-interface embedded main board. The multi-interface embedded main board comprises a central processing module which is connected with a CAN controller, an RGB-to-LVDS chip, a digital video digital-to-analog converter, a PHY module and an FPGA chip, wherein the CAN controller is provided with at least two CAN interfaces connected with the outside, the RGB-to-LVDS chip is provided with an LVDS interface connected with the outside, the digital video digital-to-analog converter is provided with a VGA interface connected with the outside, the PHY module is provided with an Ethernet interface, and the FPGA chip is provided with an ISA slot. The multi-interface embedded main board has the advantages that multiple interfaces comprising a PCI interface, the VGA interface, the LVDS interface and the like are provided, and therefore the multi-interface embedded main board can be applied to wide fields.
Description
Technical field
The present invention relates to a kind of computer motherboard, particularly relate to a kind of many interfaces embedded main board.
Background technology
Current, single-chip computer control system has been widely used in the every field such as family, industry, but these embedded systems great majority or separately application, with extraneous communication main or by serial ports or other as 485, the special purpose interface such as CAN realizes.Development along with computer technology and network technology, network communication is increasingly general, the advantage of network communication is to utilize ripe procotol, can realize that teledata is mutual fast, so it is more and more important that equipment and the external world carry out communication by network, generally all by interface chip, realize equipment and extraneous connection, the interface on existing interface chip is too single, and application is very narrow.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of many interfaces embedded main board is provided, solve the very narrow drawback of prior art application.
Object of the present invention is achieved through the following technical solutions: many interfaces embedded main board, comprise a central processing module, in described central processing module, be connected with CAN controller, RGB turns LVDS chip, digital video digital to analog converter, PHY module and a fpga chip, on described CAN controller, be provided with at least two CAN interfaces that are connected with the external world, described RGB turns provides the LVDS interface being connected with the external world on LVDS chip, on described digital video digital to analog converter, provide the VGA being connected with external world interface, in described PHY module, be provided with Ethernet interface, on described FPGA, be provided with ISA slot.
In described central processing module, be also provided with RS232 debug serial port.
On described processor, be also connected with a real time clock module.
In described central processing module, be connected with state indicating module.
Described state indicating module is LED light.
In described central processing module, be also provided with a PCI bridge, on described PCI bridge, provide at least three pci interfaces.
The invention has the beneficial effects as follows: provide abundant interface, include pci interface, VGA interface, LVDS interface etc., make this device can be applied to field widely.
