Hardware in Loop Simulation with pixhawk board using Embedded Coder for Px4 toolboxes : The base rate of the Simulink model 0 millisecond is less than 1 millisecond

I am trying to do Hardware in Loop Simulation with pixhawk board using Embedded Coder for Px4 toolboxes. I am getting the following error in my Simulink model:

The base rate of the Simulink model 0 millisecond is less than 1 millisecond. This is not supported by the PX4 Autopilot since the tick rate of NuttX OS is 1 millisecond.

To fix this error, change sample times of blocks in the Simulink model which is causing the base rate to be 0millisecond.

How do I resolve the issue?

Thanks,

Sajith

Hi Sajith Kk,

I encountered this issue. I am trying hardware in the loop with simscape multibody. Did you solve this problem ?

Hi @Sajith Kk@Osman Hökerek, I also encountered this problem. Do you have any solutions? Thank you

I got the same error when simulating. Please have a look if there is a signal builder or some block which is having continuous time rate. Also in the configuration settings -- Code Generation -- Interface -- Uncheck the Continuous Time option if it is checked. This can help to solve the problem.

I agree with Purav's suggestion. Please makesure that the base sampletime of your model is greater or equal to 1 millisecond.
