Ingenic PTZ Configuration Guide

Ensure your Buildroot configuration includes the Ingenic motors package. In your defconfig, verify the following line is present and enabled:

BR2_PACKAGE_INGENIC_MOTORS_T31=y

Loading the Module

Load the motor module with the following command ( adjust the GPIOs as needed for your hardware, see Module Configuration ):

modprobe sample_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 sample_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.

Controlling the Motors

Use the t31-kmotor command-line utility for motor control.

Note on GPIO Handling

• Be aware that depending on the specific GPIOs your hardware uses for motor control, you might experience limited or non-functional movement due to broken GPIO handling on the Ingenic platform.
• This issue may be addressed in future updates.
