Function Introduction:

Application 1:

Digital tube display infrared remote control, can be controlled at the same time corresponding to the realization of digital tube display.

Application 2:

Vibration detection infrared remote control, hand-held remote control can achieve the light background lights and other functions

Scheme description:

HS6253 is used as the main control chip. HS6253 contains 4k*16bit OTP-ROM, integrates infrared emission circuit, PWM, timer and other resources, which can realize the functions of level change wake-up, digital tube display, vibration switch detection and so on. The following is the chip package diagram.

Function description:

Digital tube display infrared remote control

Press the button to control the code sending and digital tube display. When the button is pressed, the digital tube will light up at the same time, and the digital tube can display mode, timing, temperature and other data. If the button is pressed, the backlight will be extended.

Vibration detection infrared remote control

Pick up the remote control, the vibration switch will light up the backlight when it is vibrated, and press the key to delay the backlight lighting time. For example, if you pick up the remote control and feel vibration, the backlight will turn on for 5S and then off. If you keep it still, the backlight will go out after 5s. If you receive the signal of the vibration switch or press the key within 5S, please postpone it for 5s.
