Hello Filip :-)
Is polling possible? That is if it is possible to tell whether interface
already finished commandd execution? Why did you choose 100us? If there are
command that can take longer than 100us you will have the same problem
again. Furthermore you will slow down execution of faster commands that
way. Polling seems to be the best solution in that case and you will always
get the result as soon as it is possible :-)
Best regards,
Tomek
