Hi,
Thank you for your answers.
I know RTEMS and MarteOS and they are great projects.
But I want to use the stuff those guys have put in the kernel main
line :
https://www.osadl.org/HOWTOs.howtos.0.html
It may not be the most accurate or performance may be lower than with
other solutions but I think it would match my needs for now.
Of course, if I can run Ada and get something "real time".
Otherwise, my project is quite useless.
