MCU: NEC protocol infrared remote controller
NEC protocol infrared remote controller
The communication distance of home appliance remote controller is often not high, and the cost of infrared is much lower than other wireless devices, so infrared always occupies a place in the application of home appliance remote controller. There are many baseband communication protocols for the r ...
