The red led kept blinking and windows software freezed if I connected the scope over usb.
So I tried to connect to my old PC which already had drivers and software on.
Same thing happened here, software would freeze if I connected scope to computer so it was not a driver problem.
I have found on some forum (lost it now) that it is firmware problem and that I should delete the log file in the DSOs system.
Yes. When I start the DSO software it freezes before it gets to show main window. If I unplug usb, then then app resumes to load normally.If, like biot says, the blinking red LED indicates that the firmware is loaded, does that mean that it starts to blink when you start the DSO software? I assume that the firmware is uploaded by the DSO software.
If I replug usb the app freezes again.
Thank you for explanation. Could it be that if I do connect to DSO trough UART that I could see "something" to help me fix it?
If you look at arduino. It does not have an OS but if you load a sketch that supports serial communication then you can "talk" to arduino via UART...
Or am I completely wrong?
InitializeVariables
'Open Device
Result = sdSearchDevice(DeviceIndex) 'Device found, Result=1
If Result = 0 Then
MsgBox ("DSO not found!")
End
End If
MainForm.Visible = True
'initialize hardware
Result = sdGetLevel(DeviceIndex, level(0)) 'Device index is 0
Result = sdSetTriggerAndSampleRate(DeviceIndex, TriggerSlope, ETS, Controlstate, PulseTrigger, PulseTriggerMode, PulseWidth) 'Stops responding !
Result = sdSetFilt(DeviceIndex, FiltAndTrigger)
Result = sdSetVoltageAndCoupling(DeviceIndex, Ch1Voltage, Ch2Voltage, Ch1_ACDC, Ch2_ACDC, Controlstate)
Result = sdSetOffset(DeviceIndex, levers, Ch1Voltage, Ch2Voltage, TriggerSource, level(0))
Result = sdCaptureStart(DeviceIndex)
Result = sdTriggerEnabled(deivceindex)
Initialization = False
MainForm.GetDataLoop.Enabled = True

Just to clarify the red blinking led. Led blinks red all the time when DSO has power (via usb).
This does not change in any way when I run the DSO software or SDK example.
If I remember correctly when the scope was working ok, you could hear a click of relay in DSO when you started the PC software and the led turned green.
