I can do that but Linux is not an ROS afaik. Even though i dont have
strict timing requirements , its like a sensor on i2c(producer) and
then another consumer tasks which not
only feeds on this data but also tell the i2c sensor by sending some
commands to it.

I will explore this.I was thinking if i can use Posix thread to have
two tasks one reading sensors and another sending commands to it.But
then again i am confused
if using a posix thread full fills the requirement of RTOS. The reason
I want to use RTOS is , I am porting a Microcontroller code using RTOS
(free RTOS) to Linux and
afaik FreeRTOS doesnt work on Linux.

This is interesting , do you have something to share?
