It is suggested to perform the Zero offset calibration and to use this instrument after few minutes that is on, when the temperature stabilize.Code: - The C compiler identification is GNU 5.4.0 - The CXX compiler identification is GNU 5.4.0 - Check for working C compiler: /usr/bin/cc - Check for working C compiler: /usr/bin/cc - works - Detecting C compiler ABI info - Detecting C compiler ABI info - done - Detecting C compile features - Detecting C compile features - done - Check for working CXX compiler: /usr/bin/c++ - Check for working CXX compiler: /usr/bin/c++ - works - Detecting CXX compiler ABI info - Detecting CXX compiler ABI info - done - Detecting CXX compile features - Detecting CXX compile features - done CMake Error at openhantek/CMakeLists.txt:3 (find_package): By not providing 'FindQt5Widgets.cmake' in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by 'Qt5Widgets', but CMake did not find one. It drops fast after the device is turned on (even around 50mV on a scale of +-20V). Zero offset on ADC is strongly temperature dependent.Voltage Selector: the most reliable voltage selection is +/-20V, lower hardware voltages present strong non-linearity which make useless the full ADC range of the device (for example +/-500mV range is linear just in the range +500mV -> -80mV.Acquisition: on each scan acquire 4000 bytes (2000 samples) from 2 buffers (2000 samples each buffer).Drop down to 1.2MS/s if enable 2 channels. Sample rate: maximum measured 2.4MS/s if just 1 channel is enabled.

A6 03 (acquire 64 bytes, 32 samples of 12 bits each, repeated 60 times get 2000 samples).A6 02 (acquire 64 bytes, 32 samples of 12 bits each, repeated 60 times get 2000 samples).Start of waiting cycle for data to be ready into the buffers F3 -> hardware ping (required to send regularly also when acquisition is stoped, otherwise the hardware disconnect).C1 00 00 for Channel 1, rising slope, C1 01 01 for Channel 2, falling slope) C1 -> set trigger source and slope (ie.AC 07 D0 00 03 42 00 03 42 set highest sampling rate for 2 channels enabled = 1.2MS/s) A2 -> set voltage level for each channel (ie.

AA -> set which channel to enable (ie.

A0 -> set number of channel enabled (ie.

Need to continuously send commands to the OUT Endpoint, and for each command receive the result from the IN Endpoint (both Endpoints can transfer max 64 bytes).The device got logically disconnected automatically if not receive any command after 7 seconds.
