And the master unit being connected with PC；Wireless emulator destination end includes Target Board, and be connected with Target Board from unit.
As depicted in figs. 1 and 2, master unit includes：
One controller I；
One usb interface unit, including the USB peripheral being connected on controller I, and the USB being connected with USB peripheral are inserted
Seat, USB socket are connected with PC；
One wireless transmit/receive units I, is connected on controller I using 2.4GHz Radio, is used for and the correspondence from unit
Wireless transmit/receive units II carry out radio communication；
One UART debugging interface I, is connected on controller I；
One LED light, indicate master unit working condition.
Include from unit：
One controller II；
One JTAG/SWD debugging interface, is connected on controller II, for being connected with Target Board；

The wireless SOC NRF52840 of Nodic companies can be used in controller I and controller II, and the chip uses Cortex
M4 kernels, there is USB2.0 full speed interface, 48 GPIO and other conventional peripheral hardwares.
After master-slave unit establishes logic connection, using CMSIS-DAP agreements, the work(of emulator is completed in master-slave unit collaboration
Energy.For the IDE of compatible CMSIS-DAP agreements（IDE）, such as KEIL, it is not necessary to which software is modified, it is only necessary to
Emulator type is arranged to CMSIS-DAP in IDE settings, interface type is arranged to JTAG or SWD, and pair when clock rate
The parameters such as rate, which are configured, can directly use wireless emulator, and the method to set up of this type of information is set with existing emulator
Method is identical.
After said apparatus connection, master unit is connected to PC by USB socket, passes through with the simulation software in PC
USB interface is communicated, and is communicated by wireless Radio with from unit, is responsible for PC simulation softwares and the information from unit
Interaction；From unit by JTAG./SWD debugging interface straight cuttings on Target Board, communicated by wireless Radio with master unit,
It is responsible for the information exchange of CPU and master unit；The compatible existing wired emulator software of simulation software in PC.Master unit with from
By wirelessly being communicated between unit, the information exchange between PC simulation softwares and Target Board CPU is completed in collaboration.
End, which is debugged, when wireless emulator includes multiple pc machine, and wireless emulator destination end includes multiple Target Boards, and it is more
, it is necessary to the frequency range between master and slave unit when can arbitrarily carry out emulation testing between platform PC and multiple Target Boards as needed
