NAssistant is mainly used for reading and writing function configuration, firmware update, real-time waveform, 2D and 3D trajectory, attitude and other data visualization for products, data recording , replay and export, auxiliary debugging, etc.

Attention: If the host computer cannot find the serial port or the serial port is occupied, check whether the serial port driver is installed or whether the driver is working normal.

Windows

Program installation: Windows_64bit

Serial Driver: CP210X_Windows         CH343_Windows

Note: Since there are two versions of the product, generally both drivers need to be installed.

Possible problems:

  • If the error “Missing MSVC***.dll file” is reported when opening the software. It might because that the computer lacks the corresponding runtime components of Microsoft. Select the corresponding number of bits in the system to download and install.
    Visual C++ Redistributable for Visual Studio 2017 ,  if the above installation fails or the display is successful but the dll file is still missing when opening the NAssistant program, try to install KB2999226 Patch, note, please select the corresponding version of the computer system patch, please refer to the blog about api-ms-win-crt-runtimel1-1-0.dllmissing solution
  • Open the software and report an error “because Qt***.dll cannot be found…” Please check whether the installation file is blocked by 360 and other security software silently. Please exit the security software and install again

Ubuntu

Program installation: Ubuntu_64bit

Serial Driver:

https://github.com/WCHSoftGroup/ch343ser_linux

Linux_3.x.x_4.x.x_VCP_Driver_Source_CP210x

  • If the ttyUSB port cannot be recognized after the module is connected to the Linux system, you need to install the CH343 driver.
  • Under Linux, the cp210x serial port driver is usually built in, but it supports up to 2000000 baud rate. If it is not necessary, it is recommended to use the built-in driver directly. If you need to support a higher baud rate, you can download our modified one Driver package When compiling and installing, and replacing the original driver, be sure to make a backup and operate with caution. If you encounter the driver signature problem “Required key not available”, please refer to the solution link
  • It is usually required to open the serial port permission for the first use, refer to Fix serial port permission denied errors on Linux

MacOs

Program installation: MacOs

Serial Driver:

http://www.wch.cn/downloads/CH34XSER_MAC_ZIP.html

Mac_OSX_VCP_Driver_CP210x

  • After installing the above two drivers, the software can query the corresponding port of the device (if it cannot be queried, try to restart the computer), usually containing “tty. SLAB”, since multiple ports appear under MacOs, which currently needs to be selected manually
