Abstract

The invention discloses an LED controller and belongs to the smart home field. The LED controller comprises a main control chip, a hardware watchdog circuit, a wireless receiving module, an LED driving circuit, a power source module and a memory; the output end of the wireless receiving module is electrically connected with the wireless receiving input end of the main control chip; the input end of the LED driving circuit is electrically connected with the PWM output end of the main control chip; the memory is electrically connected with the storage interface of the main control chip; the first output end of the hardware watchdog circuit is electrically connected with the reset port of the main control chip; and the count clearing input end of the hardware watchdog circuit is electricallyconnected with the timing output end of the main control chip. According to the LED controller of the invention, a hardware watchdog is adopted, so that the program of the main control chip can be prevented from going wrong; the MCU chip of the hardware watchdog can control an LED load when the main control chip fails; the memory stores various scene modules which can be conveniently selected by auser; and PWN signals are adopted to control the driving circuit, and therefore, the current of the LED load is stable.

Description

technical field [0001] The invention relates to the field of smart home, in particular to an LED controller. Background technique [0002] With the continuous development of Internet of Things technology in smart homes, more and more wireless technologies are applied to various electrical appliances. Wireless technology has many advantages such as low cost, low power consumption, and convenient control, while traditional home appliances often have the advantages of higher security, better reliability, and more in line with people's usage habits. Therefore, integrating advanced wireless technology into traditional home appliances will be more in line with consumers' usage habits and can greatly improve user experience. [0003] At present, the lighting control is mainly wired control, and the function is single. However, with the diversification of people's needs for lighting control and the inconvenience of existing products, the development of multifunctional, intelligent...
