Further, the chip is connected with at least one external chip through an external pin, and the method further comprises the following steps: the protocol selection unit sends a standard signal to a target external chip according to a current transmission channel and a target pin channel in the pins; the target pin channel is determined by sending channel confirmation information to the chip through a second user terminal connected with the chip, and the target external chip is any one of the external chips.
In this embodiment, the second user terminal may be understood as a computer device such as an upper computer, a PC-side computer, a mobile phone, and a tablet computer; the channel confirmation information may be understood as information for confirming which data transmission channel the channel for transmitting data with the external chip is.
The communication protocol conversion unit determines the current protocol conversion rule according to the target configuration information, the protocol selection unit determines the current transmission channel according to the target configuration information at the same time, the basic configuration is completed at this moment, and the received signal can be processed, the corresponding protocol conversion is carried out, and the signal is sent to the target external chip. However, at this time, the status bit of the configuration pin can be changed at will, and thus switching of communication between chips with different protocols is achieved, so that the external chip can be an external chip of different types. But the standard signal only needs to be transmitted to one of the external chips, and does not need to be transmitted to all types of external chips (even if the standard signal is transmitted, other external chips cannot correctly analyze the signal). At this time, after the protocol selection unit sends out the standard signal through the current transmission channel, the standard signal reaches the external chip through the next transmission channel, only the target external chip can successfully acquire the standard signal, and signals transmitted by other channels are useless, so that in order to avoid interference of other chips, the target pin channel can be determined, and only the target pin channel is used for sending when the standard signal is sent subsequently, and other pins are closed.
The second user terminal connected with the chip sends channel confirmation information to the chip, the channel confirmation information is also a radio frequency signal, the channel confirmation information is transmitted in a normal information transmission mode (namely, the channel confirmation information is transmitted to the protocol selection module through the modulation and demodulation module and the communication protocol conversion module), the protocol selection module sends the channel confirmation information outwards according to the current transmission channel, the channel confirmation information is transmitted to the external chip through an external pin connected with the external chip, only the target external chip in the external chip feeds back a response signal after receiving the channel confirmation information, and the second user terminal can determine a target pin channel and close other pins after receiving the fed back response signal. At this time, when the protocol selection unit transmits subsequent signals, the protocol selection unit transmits standard signals to the target external chip through the current transmission channel and the target pin channel. When the chips with other protocols need to be switched to communicate, the state bit of the pin is only needed to be reset, the steps of confirming the current protocol conversion rule, the current transmission channel and the target pin channel are sequentially executed, and then signal transmission is carried out, so that data interaction can be carried out on all external chips through a time-sharing communication method.
It should be noted that the steps described above may be interchanged in a particular order or sequence where permitted.
