The intelligent controller operation principle that the present embodiment provides is as follows:
In use, after powering on to light source controller, main control module 1 initializes the present embodiment, initializes the initialization including the hardware such as system clock, interruption, peripheral hardware, GPIO, global variable.Then pass through communication module 10 to be attached with exterior PC main frame 11, PC main frame can pass through control software design corresponding to the present embodiment and realize the control to light source controller.The control software design that user can pass through on exterior PC main frame 11 inputs corresponding control instruction, such as the relevant parameter input that data communication mode, the brightness value of passage, different flash patterns, trigger mode and PWM cycle are arranged etc..Further, external trigger mode can also select the edge that sets out accordingly.
After main control module 1 receives the PWM instruction of user's input by communication module 10, data command is carried out data verification by main control module 1, and carry out decoding corresponding data, then by the data write depositor after resolving, corresponding intervalometer is utilized to export the PWM ripple of corresponding dutycycle to LED drive circuit.Thus realizing regulating the brightness of LED light source according to pwm signal.
Further, the present embodiment regulates the brightness of LED light source by controlling the dutycycle of output PWM ripple, and dutycycle is more big, and the brightness of LED light source is more big, otherwise then more little.In LED light source drive circuit, it is pwm signal that the briliancy of high-brightness LED driver QX5241 controls the input signal of input pin DIM, output pin DRV controls the Push And Release of MOSFET pipe, QX5241 opens the dutycycle in stage by the Duty ratio control MOSFET pipe of PWM, thus controlling the brightness value of LED light source.
