Waveform 2015 Questions

What is WaveForms?
WaveForms is the user interface for the Analog Discovery 2. It is a custom toolset that allows users access to the full functionality of the Analog Discovery 2. Compatible with Mac, Windows and Linux, it provides any engineer with a portable oscilloscope, waveform generator, power supplies, data logger, logic analyzer, pattern generator, static I/O, network analyzer, spectrum analyzer, and script editor. It is the same software interface that is used with the Digital Discovery and Electronics Explorer boards.

What do I do if my Analog Discovery isn't detected?
如果未检测到您的模拟发现2，则可以遵循多个步骤进行故障排除：
  1. 确保您使用的电缆是与模拟发现2提供的电缆，并可以提供足够的电源和数据。
  2. Make sure that the Digilent FTDI driver was installed.
  3. 如果您在Mac上操作系统，尝试断开您的模拟发现2并重新启动Mac。
  4. Check out这个论坛线程on troubleshooting.
  5. Post on theDigilent Forum.

If you are on操作系统-X 10.14莫哈韦或更高版本：

  1. 删除文件digilentftdidriver.kext。
  2. 断开设备的连接。
  3. 重新开始操作系统-X。
  4. 重新连接设备。
  5. Start WaveForms. The device should now be detected.
  6. If the device is still not detected, please contact Digilent support.
I tried to use the Linux package install for Debian or Ubuntu and it failed! What do I do?
Install these packages from the terminal:
$ cd Downloads $ sudo dpkg -i digilent.adept.runtime... $ sudo dpkg -i digilent.waveforms...
