SPARQ v0.5.1 Release

Features

• Linux version now available with some limitations:
  • Multi viewport not supported
  • Currently no proper serial port device filtering
  • Linux serial port library is untested

Other Changes

• ImGuiNotify popups are no longer using multi viewports for linux compatibility. This means they are now always rendered in the bottom corner of the application window and not in the bottom corner of the monitor.

Performance

• Receive thread now sleeps if no serial port is open

Fixes

• Fixed serial port bug where baud rate was always 115200 no matter the user selection

SPARQ v0.4.2 Release

• Fix for a bug in the receive loop that made it impossible to catch up parsing messages if more than one message was in the buffer. This resulted in lost messages for receive speeds higher than a few dozen Hertz.
• Receive thread sleeps now happen at fixed intervals which improves maximum message receive rate
• Parsing of the two byte long message length in the header is now endianess aware so that the sender does not have to swap bytes

• Implementation of thread safe serial port access
• Detection of device disconnect to automatically close the port
