Load kernel module before use

ingenic-motor is a command line tool to be able to send commands to the motor.ko camera module. By default this module is not loaded and so it is necessary to enter the following commands:

modprobe motor hmaxstep=2540 vmaxstep=720 hst1=52 hst2=53 hst3=57 hst4=51 vst1=59 vst2=61 vst3=62 vst4=63

To automate this process during boot, add the line motor hmaxstep=2540 vmaxstep=720 hst1=52 hst2=53 hst3=57 hst4=51 vst1=59 vst2=61 vst3=62 vst4=63 to /etc/modules.

Module Configuration

  • hstX: Horizontal motor phase GPIO pins.
  • vstX: Vertical motor phase GPIO pins.
  • hmaxstep and vmaxstep: Specify the maximum number of steps your hardware can handle. Note that the maximum steps for the horizontal and vertical motors are passed as arguments when inserting the motor module.

Examples for Wyze Pan Cam v3

  1. connect to the camera via ssh
ssh [email protected]
  1. load the kernel module:

check if the motor module is loaded:

lsmod

if any of them are on the list then unload them first:

rmmod motor

load the modules with parameters (you may need to experiment with the hmaxstep and vmaxstep values for your specific camera):

insmod /path/to/motor.ko hmaxstep=2130 vmaxstep=1600
  1. testing

By passing the -S command line argument, the current status and x,y parameters will be returned:

ingenic-motor -S

it will look like this:

Max X Steps 2130.
Max Y Steps 1600.
Status Move: 0.
X Steps 1065.
Y Steps 800.
Speed 900.

Note: Seems like 900 is the maximum speed of the kernel module, hence why it can't be set further than that value.

Command line options

Usage : ingenic-motor
         -d Direction step.
         -s Speed step (default 900).
         -x X position/step (default 0).
         -y Y position/step (default 0).
         -r reset to default pos.
         -j return json string xpos,ypos,status,speed.
         -i return json string for all camera parameters
         -S show status

Examples

  • go to mid position of X and Y (assuming max X steps 2130 and max y steps 1600):
ingenic-motor -d h -x 1065 -y 800
  • go to position of begining of X and Y
ingenic-motor -d h -x 0 -y 0
  • go to x 1065 and y 0
ingenic-motor -d h -x 1992 -y 0
  • get camera details as json string
ingenic-motor -i
  • stop the motors
ingenic-motor -d s
  • reset the motors (to the center)
ingenic-motor -r
