It can be understood that the two processes of determining whether the control command of the processor is received through the interface control circuit 22 and determining whether the key command of the keyboard controller 25 is received are not conflicting, and may be performed simultaneously or according to a preset sequence.
Specifically, when determining whether the control instruction of the processor is received through the interface control circuit 22, it may be determined in real time whether the control instruction of the processor is received through the interface control circuit 22, or it may be determined according to a preset period, the frequency and the object of the determination and the like are not particularly limited in this application, the preset period and the preset time period and the like are preset values set in advance in the encoder 21 or the processor, and may be adjusted according to actual applications, and the specific setting manner and the content of the preset values such as the preset period and the preset time period and the like are not particularly limited in this application.
Considering that the radio frequency chip needs a processor for assistance when completing some complex functions, the processor connected with the radio frequency chip is additionally arranged, the encoder 21 controls other modules through a control instruction of the processor so as to realize more functions of the radio frequency chip, the function type and the application range of the radio frequency chip are expanded, and a worker can further control the radio frequency chip through the processor.
As a preferred embodiment, before determining whether a control instruction of the processor is received through the interface control circuit 22, the method further includes:
determining whether a manual calibration command for the processor is received via the interface control circuit 22;
if yes, controlling the radio frequency transceiver 24 to calibrate through the interface control circuit 22, and after receiving a calibration completion instruction of the radio frequency transceiver 24 through the interface control circuit 22, performing a step of judging whether a control instruction of the processor is received through the interface control circuit 22;
if not, the process proceeds to the step of determining whether a control command of the processor is received through the interface control circuit 22.
When a processor connected with the radio frequency chip exists, a worker can send a manual calibration instruction through the processor, and when the encoder 21 receives the manual calibration instruction of the processor through the interface control circuit 22, the interface control circuit 22 can control the radio frequency transceiver 24 to calibrate, so that the manual calibration process is completed. It can be understood that both the manual calibration process and the calibration process may be performed, or only one calibration process may be performed, and the specific implementation manner of the manual calibration process and the manual calibration instruction and the like are not particularly limited herein.
Specifically, when determining whether the artificial calibration instruction of the processor is received through the interface control circuit 22, it may be determined in real time whether the artificial calibration instruction of the processor is received through the interface control circuit 22, or it may be determined according to a preset period, the present application such as the determined frequency and the determined object is not particularly limited herein, the preset period and the preset time period are preset values set in advance in the encoder 21 or the processor, and may be adjusted according to actual applications, and the present application such as specific setting modes and contents of the preset values such as the preset period and the preset time period is not particularly limited herein.
Considering that when a processor connected with a radio frequency chip exists, a worker can complete manual calibration of the radio frequency transceiver 24 through the processor, judgment of the encoder 21 on a manual calibration instruction is increased, manual calibration is easy to achieve and convenient to control, parameter errors caused by external environments or internal devices can be effectively reduced along with the calibration process, accuracy and reliability of the radio frequency transceiving process are further improved, and safety of the radio frequency transceiving process is guaranteed.

the encoder 21 is used to implement the steps of the radio frequency transceiving method as described above.
It is understood that the specific parameter settings, material shapes, and the like of the rf chip are not particularly limited herein, and may be adjusted according to the actual application environment of the rf chip. The radio frequency chip provided by the invention can support a plurality of working modes, including a processor-controlled working mode and a Stand all mode (independent mode), and the whole radio frequency transceiving process can be completed without a processor in the Stand all mode.
Referring to fig. 5 and fig. 6, fig. 5 is a schematic flow chart of another radio frequency transceiving method according to the present invention; fig. 6 is a schematic flow chart of another radio frequency transceiving method provided by the present invention. Fig. 5 is a schematic flowchart of the rf chip in a processor-controlled operating mode, fig. 6 is a schematic flowchart of the rf chip in a Stand Alone mode, POWER ON and POWER OFF indicate POWER-ON and POWER-OFF of the rf chip, and Calibration refers to a Calibration process of the rf transceiver 24.
When the processor is in a control working mode, after the processor is powered on, the radio frequency chip reads (reads) the configuration information which is burned in advance from the NVM, and then enters an IDLE state to wait for a next instruction of the processor; after completing a series of Calibration, the rf chip may enter a TX (transmit) state or an RX (receive) state; after TX or RX is completed, the processor may control the rf chip to enter a Sleep state.
In the Stand Alone mode, after the power is on, the radio frequency chip reads the configuration information which is burned in advance from the NVM, and then enters an IDLE state for key detection. If no key action is detected, the radio frequency chip can enter a Sleep state; if the key action is detected, the radio frequency chip executes corresponding transmitting operation according to the key value, and can enter a Sleep state after the transmission is finished. In Sleep state, the radio frequency chip only retains the key wake-up function and a small amount of configuration information, and the consumed current is very low. Once the key wake-up module detects that a key action occurs, the radio frequency chip wakes up from the Sleep state, then reads information in the NVM, and enters the next key detection and transmission process.
