Design of STM32-based RGB lighting control system

The wave of the "internet celebrity" era has promoted the development of fill lights, photography lights, etc. To achieve better visual effects and precise lighting adjustments, a PWM-based RGB photography lighting control system with STM32 as the core is designed. The overall hardware platform architecture with the STM32G070 series chip as the core processor is described, and the hardware principle is introduced in detail from a modular perspective, followed by the PWM dimming principle and the software algorithm process. This system is portable across different operating systems, having strong timeliness and low power consumption. It can also communicate with a mobile phone APP through the Bluetooth protocol to achieve remote and accurate digital control of photographic illumination. It can run stably and be successfully applied to the product.
