Pololu Maestro QMI driver was updated so that it can be used also with Pololu instruments that are in the default UART mode, by using a special "uart:..." transport string. For this we need
boardandbusiomodules fromadafruit-blinkapackage, which are imported as "lazy imports". The latter is imported through newqmi_uartmodule, which has an extension of thebusio.UARTclass so that it is compatible withQMI_Transportclasses to use with the special transport string, and to use the same read-write calls.During the course of this refactoring and extension, also the
psutilpackage was updated such that it would not work anymore inqmi_proc.py. This is due to moving the_snicaddrinternal variable in the package. Theqmi_proc.pywas adapted such that it checks the version number ofpsutiland selects followingly the correct location of the_snicaddr.
