Sound-collecting method for implementing ultrasonic tactile stick radio through integrated radio chip

The invention relates to the field of embedded technologies, in particular to a sound-collecting method for implementing an ultrasonic tactile stick radio through an integrated radio chip. The sound-collecting method for implementing the ultrasonic tactile stick radio through the integrated radio chip comprises the following steps: firstly, initializing an MCU (Microprogrammed Control Unit) through a program; setting a connection pin which is connected with a pin RST at high level; performing initialization setting on the chip; searching for channels by the program through a channel-searching function; during changing of chip parameters and channel searching, inquiring a state bit STC (completion of searching/adjustment) of a 0AH register needing to be inquired by the program, and judging whether or not parameter setting or channel searching is completed; calling a function for performing next searching every time after successful completion of channel searching. By adopting the sound-collecting method, the p
