Abstract

The invention discloses an LED controller, which relates to the field of smart home, comprising: a main control chip, a hardware watchdog circuit, a wireless receiving module, an LED drive circuit, a power supply module and a memory; the output terminal of the wireless receiving module and the main control chip The wireless receiving input end of the LED drive circuit is electrically connected to the PWM output end of the main control chip; the memory is electrically connected to the storage interface of the main control chip; the first output end of the hardware watchdog circuit is reset to the main control chip The ports are electrically connected, and the counting and clearing input end of the hardware watchdog circuit is electrically connected with the timing output end of the main control chip. The present invention adopts a hardware watchdog to avoid errors in the main control chip program; the MCU chip of the hardware watchdog can control the LED load when the main control chip fails; there are various scene modules stored in the memory, which is convenient for users to choose; The signal controls the driving circuit, and the LED load current 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...
