Hi
I am still working on my application including a linear actuator. In short, I want to move the linear actuator outwards or inwards based on a sensor input. This I am doing in a loop where I am regularly updating the speed and direction based on the new sensor data.
The problem is that the program sometimes freezes and this always happens with an error message down to the SOLO. I encountered the following error now a few times:
^CTraceback (most recent call last): File "tilt.py", line 222, in <module> tilt_back() File "tilt.py", line 207, in tilt_back __solo_driver.set_direction(1) # direction File "/home/pi/.local/lib/python3.7/site-packages/SoloPy/solo_motor_controller.py", line 182, in set_direction return self.__exec_cmd(cmd) File "/home/pi/.local/lib/python3.7/site-packages/SoloPy/solo_motor_controller.py", line 25, in __exec_cmd while ser.in_waiting: File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 467, in in_waiting s = fcntl.ioctl(self.fd, TIOCINQ, TIOCM_zero_str) KeyboardInterrupt
Sometimes this error happens on __solo_driver.set_speed_reference() and it seems to me that there is a problem in reading or writing to the device.
I am glad for any help.
Kind regards,
