An LED control system includes a platform controller unit, a peripheral interface control chip connecting with the platform controller unit, and an LED unit connecting with the peripheral interface control chip. The platform controller unit outputs control instructions to the peripheral interface control chip. The control instructions outputted by the platform controller unit is transformed via programming the peripheral interface control chip, so that the on/off state of the LED unit as well as brightness and color of light emitted from the LED unit can be controlled by pulse signals output from the output ports of the peripheral interface control chip. |
