Have a simple question, we’re using FreeRTOS in a school project in wich we’re programming a robot with one master and different slaves like the main control and the sensor and actuator controls. I’m designing the main control of the robot and looking for a way to implement a critial stop through a “panic button”. I want to do it with a messageque to the task wich is responseble for sending the messages to the slaves. But because it’s a critical event and anther event could have the communication resource I want to send a messege through a messagecue with a “high” priority to the “critical stop” message.
Is it possible in RTOS to set a certain (higher) priority to a single message within a messageque? I can’t seems to find such call in the information section of the FreeRTOS.org page.
Could anyone answer this question and tell me what i have to call. Or present me an altered code of FreeRTOS wich can do this, if you have such code?
Tnx a lot for your time in advance.
