Embodiment Construction
[0064] 1. Hardware design of wireless communication device for home appliances
[0065] The wireless communication device for home appliances includes a single-chip microcomputer control circuit and an independent radio frequency circuit. The processor of the microcontroller control circuit is ATMEGA32L, the operating voltage is 3.3V, and the crystal oscillator frequency is 4MHz. The processor in the wireless radio frequency circuit adopts nRF24L01, and the crystal oscillator frequency is 16MHz. The pin connection between the microcontroller control circuit and the radio frequency circuit is as follows:
[0066] The 43-pin (CE) of the MCU is connected to the 1-pin (CE) of the NRF24L01 chip; the 44-pin (CSN) of the MCU is connected to the 2-pin (CSN) of the NRF24L01 chip; the 1-pin (MOSI) of the MCU Connect with pin 4 (MOSI) of the NRF24L01 chip; pin 2 (MISO) of the microcontroller is connected with pin 5 (MISO) of the chip NRF24L01; pin 3 (SCK) of the microcontroller is conn...
