My Asctec Pelican has an atomboard with two UART ports (/dev/ttyUSB0,/dev/ttyUSB1). One of them is used by the HLP and now I want to use the other one for my laser range finder. Can I just connect the device directly to UART1. Is there anything I should be careful about? I dot not want to damage any part, so I need to make sure everything is fine, Thank you very much.
However, when I plugged it into Pelican using the USB port, it can not be recognized by the ftdi_sio driver. I mean I thought it would be assigned the port /dev/ttyUSB2.
After I add the device ID to " /sys/bus/usb-serial/drivers/ftdi_sio/new_id ", it appears as /dev/ttyUSB2.
But I observed a huge delay in the sensor readings using the ROS driver. Another problem is that the device is not identified again after a reboot.
Is there anyway to fix the problem?
I did not try to use the UART1 port because I am not sure of the safety in doing so.
