  1. Hi, We have a measurement setup with multiple Analog Discovery 2 units hooked up to a single Linux computer. The AD2 units are used by separate processes. If multiple processes have opened AD2 devices, and one of them terminates without explicitly calling 'FDwfDeviceClose' (e.g. due to a hard KILL signal), that device remains unavailable, i.e., FDwfEnumDeviceIsOpened() returns 1 in its pfIsUsed parameter, even though the device is not in use anymore. The only way I found to make such a device available for use again is to terminate all other programs that control an AD2 dev
  2. Hi, I'm trying to capture a 400kHz I2C waveform for a second or two using the logic analyzer function. Because the AD2 buffer size is small I am using record mode. When I do this with the default device configuration in the device manager (option 1 16x4k for Logic) I get the error "Samples were lost! Reduce sample rate". If I reduce the buffer dize and the sample rate I can change the message to "Samples could be lost! Reduce sample rate". My understanding is that I should be able to operate at 1-2MHz and that it's the USB bandwidth in conjunction with the buffer size that is the
