Example Embodiment

[0043] Example 1

[0044] Such as image 3 As shown, this embodiment provides an LED offline control data processing device, which includes a storage module 11, a control module 12, and a data processing module 13. Preferably, the control module 12 communicates with each other through a serial peripheral interface SPI (Serial Peripheral Interface) The control terminal CMD of the storage module 11 is connected, and the control terminal of the data processing module 13 is connected through other communication methods (such as CPU parallel port mode) to realize the data communication function. The data processing module 13 is also connected with the data terminal of the storage module 11, and the control module 12 is used for Send control commands to the storage module 11 and the data processing module 13 to control the data processing module to read data from the storage module; the data processing module 13 is used to respond to the control signal of the control module 12 to read f...

Example Embodiment

[0048] Example 2

[0049]On the basis of Embodiment 1, the storage module 11 uses a removable storage card, such as an SD card, which is inserted into a fixed slot for fixing the storage card, and the control module 12 uses a microcontroller MCU (Micro Controller Unit), such as The AVR single-chip microcomputer and the data processing module 13 preferably use Field-Programmable Gate Array (Field-Programmable Gate Array) or Complex Programmable Logic Device (CPLD), for example, Stratix III series FPGA launched by Altera Corporation. The single-chip microcomputer is low in price, strong in control ability, FPGA data processing ability is strong, and the application is flexible. The two combine their strengths to achieve the goal of low cost and high performance.

Example Embodiment

[0050] Example 3

[0051] On the basis of embodiment 1, the offline control device of this embodiment further includes an input module (not shown in the figure), such as a handheld wireless input device, a wired input device, or a key input device, which is connected to the control module 12 Connected and used to input control commands to the control module 12, such as control commands for controlling playback content, playback speed, and playback mode.

[0052] In another example, the offline control data processing device of this embodiment may also include a display module (not shown in the figure), for example, a liquid crystal display, a digital tube display device, or an indicator light may be used to provide a platform for human-machine communication. The module 16 is connected with the control module 12 and is used to display system working status information.

[0053] As another example, in an offline control data processing device, the control module 12 and the data proc...
