# Nu-Link2-Pro debugging and programming adapter
When using software development tools above, you may need an USB adapter.
We introduce you a new feature-rich Nu-Link2-Pro adapter here.

An overview picture of software tools, adapter and targets
### The firmware of Nu-Link2-Pro adapter
All Nu-Link2-Pro firmware binary files can be found [here](./Latest_NuLink_Firmware)
User can re-program Nu-Link2-Pro to another .bin file by the following instructions (Windows OS)
1. Press the button on Nu-Link2-Pro and plug in USB cable.
2. A "Nu-Link2-Pro" disk will show. (If you see disk name is "NuMicro MCU", it will upgrade target device firmware instead of Nu-Link2-Pro itself)
3. Drag and drop Nu-Link2-Pro firmware .bin file into the disk.
4. Re-plug the USB cable and it's done.
More options for NuLink2FW (configuration file NU_CFG.TXT)
1. When you upgrade the NuLink2FW.bin larger than version v7143, open NU_CFG.TXT file in pop-up "NuMicro MCU" disk, you will see some options in NU_CFG.TXT.
2. For example, you can see BRIDGE_MODE and CMSIS-DAP options.
* Set BRIDGE_MODE=1 then re-plug in USB cable, the pass-through bridge function of Nu-Link2-Pro will be enabled (The word Nu-Link2-Bridge will be used to represent the pass-through bridge application on Nu-Link2-Pro adapter). Nu-Link2-Bridge pass-through the data between VCOM port and I2C/SPI/RS485/CAN interfaces.
(You will see an "Nu-Link2-Bridge Virtual Com Port" in device manager.)
* Set BRIDGE_MODE=0 then re-plug in USB cable, an USB HID interface supports ISP Tool will be enabled. This USB HID interface doesn't pass through data, it communicates with ISPTool via HID_ISP, and offers I2C/SPI/RS485/CAN interfaces for ISPTool.
(You will see an USB HID interface [HID_ISP][VID:0x0416, PID:0x520*, interface:05] in device manager.)
* Set CMSIS-DAP=1 then re-plug in USB cable, it presents one more interface HID_CMSIS-DAP, this is handy if you want to use CMSIS-DAP protocol.
(You will see an USB HID interface [HID_CMSIS-DAP][VID:0x0416, PID:0x520*, interface:06] in device manager.)
