Hi,

i just tried to use the given examples and get the following stacktrace:

pi@raspberrypi:~/PTZ-Camera-Controller/pyCode $ sudo python FocuserExample.py Traceback (most recent call last): File "FocuserExample.py", line 233, in main() File "FocuserExample.py", line 225, in main curses.wrapper(draw_menu,camera) File "/usr/lib/python2.7/curses/wrapper.py", line 43, in wrapper return func(stdscr, *args, **kwds) File "FocuserExample.py", line 206, in draw_menu RenderMiddleText(stdscr,k,focuser) File "FocuserExample.py", line 84, in RenderMiddleText focus_value = "Focus : {}".format(focuser.get(Focuser.OPT_FOCUS))[:width-1] File "/home/pi/PTZ-Camera-Controller/pyCode/Focuser.py", line 120, in get self.waitingForFree() File "/home/pi/PTZ-Camera-Controller/pyCode/Focuser.py", line 69, in waitingForFree while self.isBusy() and count < (5 / 0.01): File "/home/pi/PTZ-Camera-Controller/pyCode/Focuser.py", line 65, in isBusy return self.read(self.CHIP_I2C_ADDR,self.BUSY_REG_ADDR) != 0 File "/home/pi/PTZ-Camera-Controller/pyCode/Focuser.py", line 56, in read value = self.bus.read_word_data(chip_addr,reg_addr) IOError: [Errno 121] Remote I/O error`

I'm using a Raspberry Pi Model 3 B with Rasbian OS 10 Buster.

Hope you can help me solving this problem.
