I want to read value in RAM with given address and length of data. I have read several RTE API's and I think there is no API provide my needs. I hope there is API like Rte_Ram_read(address,length) or something else. I found API for access PerInstanceMemory or InterRunnableVariable, but they didn't work like what I want.
My question, Is there any API like what I want? or I have to create that by myself? or is there any advice for me?
The question is why do you want to do that?
The idea of a software component is that it is independent of the hardware and self-contained. To communicate with other components you should use ports. To communicate with runnables you should use InterRunnableVariable or PerInstanceMemory.
What's the use case behind reading something from RAM? Where does the data come from?
