Abstract
A method and a device for improving debug time of a display apparatus are provided. The display apparatus includes an input signal connector for receiving an external input signal, an MCU, a bus and a plurality of units. The input signal connector is connected to the MCU via the bus, and the MCU is connected to the plurality of units via the bus. First, whether the MCU has entered the debug mode is detected; and when it is detected that the MCU has entered the debug mode, the bus switches to directly connect to the plurality of units in the display apparatus for allowing the external signal transmitted directly to the plurality of units for debugging.
Claims20
A debug method for a display apparatus, the display apparatus comprising an input signal connector for receiving an external input signal, an MCU, a bus, and a plurality of units, wherein the input signal connector is connected to the MCU via the bus, and the MCU is connected to the plurality of units via the bus, the debug method comprising:
- detecting whether the MCU has entered the debug mode;
- and
- switching to directly connecting to the plurality of units in the display apparatus for allowing the external signal transmitted directly to the plurality of units for debugging when the MCU enters the debug mode.
A display apparatus having a built-in debug function, comprising:
- an input signal connector, for receiving an external input signal;
- an MCU, coupled to the input signal connector via a bus for receiving the external input signal;
- a plurality of units, controlled by the MCU, comprising different functions, wherein the MCU is coupled to the units via the bus;
- and
- a switch, disposed between the input signal connector and the units, for switching the controlled connections thereof,
- wherein when it is detected that the MCU has entered a debug mode, the switch switches the bus to directly connect to the plurality of units so as to allow the external signal to directly transmit a control signal complying with a protocol of the bus for debugging.
