Qt 5.8 with QtSerialBus released

[A.Hartmann]

Qt 5.8 Beta was released last friday [1] and now officially contains the QtSerialBus module.

QtSerialBus allows easy CAN bus access from within Qt applications.

Peak CAN bus adapters are supported by the PCAN-Basic-API under Windows (USB and PCI devices), and by SocketCAN under Linux. A simple GUI and a console example are included to try out the features.

Please try this beta and report all issues to the Qt bug tracker [2]
Thanks.

Hi,

and last week Qt 5.8 final was released [1].

The new QtSerialBus module [2] makes it much easier to access CAN hardware from for Qt programs.

Hello,

I am having a problem with the Qt CAN example, it runs perfectly on windows and I am able to send and receive messages. On Linux I i installed the PCAN driver and tested it and it works, but when I use the Qt CAN example I always have an error when connecting to the peak can device: "A PCAN Channel has not been initialized yet or the initialization process has failed" or sometimes this error:" An operation is not allowed due to the current configuration ".

Can someone please tell me what could be the problem? (I am a rookie)

Thanks in advance

Hi rachedrech,

We lately had a report about this issue and the problem is resolved in Qt 5.9.3. Please consider updating.
