Raspberry pi 2B+ ros indigo
Hi guys I am running ros indigo on my raspberry pi 2b+. I created robot driver for my arm manipulator which is implementation of 3 processes. Main process is service and communicates via usb-serial interface/rs232. 2nd proces is servis which generate messages for main procesess and controlling them and do some basic commutations and the last one is joint_states topic which is communicating with main proces via servis and publishing joint_states. Firstly i had this program on my computer and it could easily publish joint states every 80 ms. But after compilation on raspberry pi . I takes 400 ms to publish joint states of my 6 -dof manipulator and I am not talking about any other control. Is it normally so slow or am I doing something wrong. Can you give me some hints ? Thank you for any advice. Is any there problem with socket communication and publishing topics on raspberry? because it is really so slow
Thanky you for your answers
