Using the rosserial_stm32( library, I am trying to publishing a message(std_msgs/UInt32) on the /chatter topic at a rate of 5Hz. The message gets published at a rate 20% lower as seen from the screenshot below. When estimating the time of execution, I found the time taken for each loop to be around 236ms which is roughly 4.2Hz. image description

I am also getting a Lost Sync with Device error very frequently (once every 2 minutes) as the code hangs. Any pointers to solutions? Thanks!

Turns out I had set up the system clock incorrectly on the STMCubeMX software. Works quite well now! Closing the thread.
