      Q:

      Is the address on the i2c bus of the ov9281 camera module still 0xc0? Or has this address changed perhaps?

      A:

      The address for i2c bus of OV9281 is 0x60,and it won’t change.

      Q:

      Is it possible to use an external 21hz clock to trig the acquisition of a sequence of 21 frames on the Arducam OV9281 MIPI 1MP Monochrome Global Shutter Camera Module for Raspberry Pi?

      A:

      Yes, here is the demo for your reference:

      Q:

      Would it be possible to receive the source code to modify the library for internal purpose? ( Antonio Doncel)

      A:

      We don’t offer the driver source code, we provide the sensor API. You can view specific functions in arducam_mipicamera.h

      int arducam_write_sensor_reg(CAMERA_INSTANCE camera_instance, uint16_t address, uint16_t value);

      int arducam_read_sensor_reg(CAMERA_INSTANCE camera_instance, uint16_t address, uint16_t *value);

      Q:

      We got this Camera from the Amazon but not able to get it to work, we followed all the instructions. (About the software problem)( Nikhil Gaikwad)

      A:

      Since it takes more time for PNG encoding, our default time is not enough to end the encoding, so it returns timeout. I have optimized and updated the MIPI_Camera library, please download the latest library test

      https://github.com/ArduCAM/MIPI_Camera.git. You could try to modify the encoding time and open capture.c.

      Q:

      Does 16MP ArduCam IMX298 and 18MP ArduCam CMOS AR1820HS

      can be connected directly to RPI CSI connector?

      Does these cameras support hardware trigger?

      A:

      Both of the cameras can be connected to RPI CSI connector directly .

      However, they don’t support external trigger feature at the present.

      You could use Arducam USB 2.0 shield Rev.E (SKU: B0175) ,which can work with the cameras for external trigger.
