* [Please fill in during the registration stage ↓]
* * 1. More than ten years of experience in electronic product R&D, mainly engaged in hardware design (functional design, schematic design, PCB design, research device debugging, software function development, debugging. Embedding development).
* * 2. Three-channel RGB color light controller. The hardware design is simple (no more protection and other safety checks are added), and the main work is software design and control operation of the WINDOWS host computer.
* [Please fill in ↓ during the competition stage]
* * 1. Describe the project details
* 1. Project name: Three-channel RGB lantern controller, hardware, software, and host computer are all original.
* 2. Simple hardware circuit (no protection, amplification circuit):
* 1), 1 MCU;
* 2), 1 LDO;
* 3), 1 electrolytic capacitor;
* 4), 1 MICRO USB connector ;
* 5), 5 terminals;
* 6), 12 resistive components;
* 7), 1 LED display light;
* 8), 3 RGB light strips, which can be connected in series for display.
* 3. Mainly works on software design and host computer design.
*1), each channel can independently control brightness 0%, 30%, 60%, 100%.
*2), each channel can be divided into 6 groups and controlled individually.
*3), each group can have 6 working modes, the number of lamp beads, speed, display direction, and display color parameters can be controlled.
*4), working modes include: CPU temperature indication mode, static mode, rainbow mode, gradient mode, pulse mode, wave mode.
*5), the WINDOWS host computer communicates with the motherboard through USB.
*
* * 2. Describe the challenges faced by the project and the problems solved
* 1: Flexible control of the display of each RGB lantern,
*
* * 3. Describe the key points involved in the hardware and software parts of the project
* 1. Hardware : Determine the selection of three RGB color light pins, suitable for DMA TO PWM output.
