Self-learning infrared remote controller based on STM32
Abstract：A low power consumption and high performance learning infrared remote controller is presented.. The working principle and software hardware of the remote controller are introduced, and the realization of infrared coding learning is described in detail.. The remote controller the principle of measuring the pulse width, with self-learning function, memory and learning infrared remote controller code, and stimulated emission, makes a remote device can replace a plurality of remote control home appliances of different, really improve the learning type remote controller of intelligent functions.
This design mainly uses the STM32 microcontroller as the core, integrated application of the microcontroller interrupt system, timer, timer and other knowledge, the advantages of infrared light. The basic principle of infrared control, the structure and control of infrared control is introduced, and then the circuit design and some related optoelectronic devices are introduced.. Then, the hardware design and the software design are the design of the software, which includes the upper computer and the lower computer.. Finally, debug and summarize. Finally, the compatibility of different infrared remote controller is solved.
