As shown in fig. 1, an LED lamp start control system of a soar motherboard includes a soar CPU11, a GD32 single chip 12, a not gate, an LED lamp 14, a resistor R1, and a tri-state level conversion chip 13; in this embodiment, the model of the tri-state level conversion chip 13 is RS8T245, and the model of the GD32 single chip 12 is GD32F 10X. In this embodiment, the GD32 single chip 12 is also responsible for controlling the start and stop of the main board for the soar, and also provides the 3.3VSB power supply in a normalized manner.
The GPIO pin of the soar CPU11 is connected to the input terminal of the tri-state level conversion chip 13, the GD32 single-chip microcomputer 12 is connected to the soar CPU11, and in this embodiment, the GD32 single-chip microcomputer 12 is connected to the soar CPU11 through a UART serial port.
A GPIO pin of the GD32 single chip microcomputer 12 is connected to an enable terminal of the tri-state level conversion chip 13, and another GPIO pin of the GD32 single chip microcomputer 12 is connected to an input terminal of the not gate through a resistor R1, in this embodiment, a resistance value of the resistor R1 is at least 100K, and preferably, the resistor R1 is a resistor R1 of 100K. The output end of the tri-state level conversion chip 13 is connected with the input end of the NOT gate, and the output end of the NOT gate is connected with the LED lamp 14. Before the soar processor is started, the GD32 single-chip microcomputer 12 controls the tri-state level conversion chip 13 to enter a high-impedance state, the state of the GPIO pin of the soar CPU11 is isolated by the tri-state level conversion chip 13, and therefore the LED lamp 14 cannot be in an unexpected state. When the FT CPU11 is operating normally,
a starting control method of an LED lamp of a Feiteng mainboard is based on an LED lamp starting control system of the Feiteng mainboard and comprises
In the process that the Feiteng CPU11 enters the system, when the enable end of the tri-state level conversion chip 13 receives a control level, the tri-state level conversion chip 13 outputs a high-resistance state, if another GPIO pin of the GD32 single chip microcomputer 12 outputs a low level, the LED lamp 14 is turned on, and if another GPIO pin of the GD32 single chip microcomputer 12 outputs a high level, the LED lamp 14 is turned off.
When the soar CPU11 enters the system, the soar CPU11 automatically runs scripts to adjust the GPIO state, and sends a signal to the GD32 single-chip microcomputer 12 through a UART serial port, the GD32 single-chip microcomputer 12 outputs a low level to the enable end of the tri-state level conversion chip 13 after receiving the signal, and then the control right of the LED lamp 14 is exchanged to the soar CPU 11.
The design key point of the invention is that the initial state of the LED lamp can be indirectly controlled by connecting the other GPIO pin of the GD32 singlechip with the input end of the NOT gate through a resistor R1, and particularly, the GPIO pin of the GD32 singlechip is connected with the enabling end of the tri-state level conversion chip, so that the LED lamp is prevented from generating an unexpected state in the process of entering a system by a Feiteng CPU, and the whole control method is simple.
