Touch display device with module recognition and automatic configuration mechanism

Abstract

This invention relates to a touch display device with a module identification and automatic configuration mechanism, comprising a touch display module, a processor, and an expansion interface. When the processor detects an external device connected to the expansion interface, it receives the module identification information of the external device to determine its module type. The processor then loads the corresponding configuration data based on the module type to activate the external device. In this way, the processor can automatically identify the module type of the external device and automatically activate it without manual configuration, achieving a plug-and-play effect for the external device.

Claims

1. A touch display device with module identification and automatic configuration mechanism, comprising: A touch display module; a processor electrically connected to the touch display module; An expansion interface is electrically connected to the processor and powered to an external device. When the expansion interface is connected to the external device, the processor detects the external device connection and receives module identification information sent by the external device through the expansion interface. The processor determines a module type of the external device based on the module identification information, loads corresponding configuration data based on the module type, and enables the external device based on the loaded configuration data.

2. The touch display device with module identification and automatic configuration mechanism as described in claim 1, wherein, After the processor loads the configuration data, it first initializes the expansion interface and generates a control parameter, and then enables the external device according to the control parameter.

3. The touch display device with module identification and automatic configuration mechanism as described in claim 1, wherein, The expansion interface includes: a power supply port electrically connected to the processor and powered to the external device to supply power to the external device; a data transmission port electrically connected to the processor and powered to the external device to exchange data with the external device; and an identification signal port electrically connected to the processor and powered to the external device to receive module identification information sent by the external device.

4. The touch display device with module identification and automatic configuration mechanism as described in claim 3, wherein, The data transmission port can be a Universal Asynchronous Receiver / Transmitter (UART), a Sequential Peripheral Interface (SPI), an Integrated Bus (I2C), or a General Purpose Input / Output (GPIO).

5. The touch display device with module identification and automatic configuration mechanism as described in claim 1, wherein, The module identification information includes voltage level information, digital signal information, or communication response signal information.

6. The touch display device with module identification and automatic configuration mechanism as described in claim 1, wherein, The module identification information includes a module type, a function code, or parameter data.
