Solution

Huayun 2.4G remote control, using AD-RF01 and AD-RF02 SOC type wireless transceiver chip, this type of chip is 1 / 0 type, with OTP as the program storage basis, comes with 2.4G high-speed wireless transceiver chip microcontroller. The wireless transceiver chip operates in the 2.400-2.483GHz world-wide ISM band. It integrates functional modules such as RF transceivers, frequency generators, crystal oscillators, and modems, and supports one-to-many networking and communication modes with ACK. The transmit output power, working channel, and communication data rate can all be configured. It adopts GFSK communication mode, supports automatic response and automatic retransmission, and has its own scrambling code and CRC check function. Can be applied to wireless mouse and keyboard, TV and set-top box remote control, wireless game controller, active wireless tags, smart home and security systems, remote control toys and other fields.

 

The AD-RF01 has a built-in 2KW OTP program memory and 128 bytes of data memory. In addition, the AD-RF01 provides a 16-bit hardware counter, two 8-bit counters (Timer2, Timer3), and three 11-bit counters (PWMG0, PWMG1,PWMG2) can generate PWM. In addition, AD-RF01 also provides a hardware comparator and 1/2VDD bias voltage for driving LCD.
