It can happen that under some conditions daqIDEA crashes and thus the daqIDEA window disappears. This is more likely to happen with the older winIDEA versions as described below.
daqIDEA is a winIDEA tool written in Python. It requires winIDEA SDK and some other Python modules in order to function properly. For this reason, the portable winIDEA installation copy contains a Python distribution with the required modules. Changing the internal Python setup can cause daqIDEA to malfunction and even crash rendering it useless.
If, for example, you start experiencing problems with daqIDEA, you may try to
make a clean winIDEA installation:
1. Create a new empty installation folder.
2. Install a new winIDEA in the prepared installation folder from the previous step.
If daqIDEA starts working when using newly installed winIDEA, this means that the previous installation has very likely been compromised in this way.
3. (optional) Check the version of the used Python winIDEA SDK. It must match the used winIDEA version. The previously described two-step procedure already includes the correction of this discrepancy if it occurs.
Demo Mode is disabled by default in winIDEA. When enabled, daqIDEA data acquisition does not work!
In the older winIDEA versions, starting daqIDEA data acquisition during Demo Mode enabled can cause daqIDEA to crash. In the newer winIDEA versions, the error message will pop up as a reminder when this is tried, and daqIDEA data acquisition will not start under this condition. The solution here is to disable Demo Mode.
Using older winIDEA versions can cause daqIDEA crashes with specific devices (like NXP MPC5554) under specific conditions. This was fixed with winIDEA version 9.21.37. Migration to that version of winIDEA or newer will solve this kind of daqIDEA crash.
