v5.2.0 Changelog

Near Infrared Camera:

• Add live configuration when streaming
• Add many new IR settings (de-noise, led intensity, strobe lights, etc)
• Change custom IR sensor registers
• Auto exposure mode (This is done manually, so it's experimental. Expect bugs).

User Calibration Editing:

• Add Accelerometer/Gyroscope user calibration editing
• Add Stick device factory parameters editing. Helps when you have drifting issues, that can't be fixed by calibrating the stick. Just raise the deadzone value.

Debugging / Troubleshooting:

• Add 2 command line options:
• -d: Dumps the communication packets into a log text file
• -f: Forces the app to not check for connection again. Helps in some cases that the app reports that the controller was disconnected.

Others:

• Organize the IR/Playground/Calibration panels a little better
• Many bugfixes and optimizationsbugfixes/optimizations

Prerequisites:
