Version check!

Starting with version 2020.4, a version check is implemented in the PClient. Only if the major and minor version of the used development version and PClient version are the same, the project will be loaded. Otherwise a red warning screen will be shown that informs of the version discrepancy.


Important disclaimer!

Please note that for i.MX6 devices, installing the OS 2.x will prohibit a downgrade back to OS 1.x!

Once an OS 2.x is installed, there is currently no way to downgrade back to OS 1.x!


Limitations in the demo version

The demo version is limited to the creation of up to 2 pages and up to 5 user-defined variables.

Additional pages or variables cannot be created.

If a project is opened that exceeds one of these limitations, the project can not be downloaded to the device.

Read here how to get a license!


Known issues

- GIF files can only be used as Image to Display for Picture Graphic objects, but not as background, needle, border etc. images

- For devices with multi touch, buttons should not be put too close together, especially for contrary functionalities (up/down or plus/minus). With distances < 1.5 cm a second press can sometimes not be recognized as such but will instead be registered as a false coordinate for the first finger, resulting in an unwanted release for the first button.

- Properties of objects should not excessively be changed before the modifications were actually seen on the screen. This is especially relevant with i.MX 35 devices and string properties like Image to Display.
