Re: [Paparazzi-devel] Digital_cam module / DC_SHOT overflow

[Felix Ruess]

Hi,

I'm wondering why this limit is in there at all...
Also this should then be adjusted in the DC_INFO message as well, where the dc_buffer is transmitted as int8 instead of uint16.

@Christophe, any comments on that?

Cheers, Felix

You are right
I increased the IMAGE_BUFFER to high value and the problem not occur anymore.

Change the value in yout airframe file:

  <modules>
   <load name="openlog.xml"/>
    <load name="nav_catapult.xml"/>
    <load name="digital_cam.xml">
      <define name="DC_SHUTTER_LED" value="CAM_SWITCH_LED"/> <!--CAM_SWITCH_LED-->
      <define name="DC_PUSH" value="LED_OFF" />
      <define name="DC_RELEASE" value="LED_ON" />
      <define name="DC_IMAGE_BUFFER" value="16535"/>
    </load>

Subject: [Paparazzi-devel] Digital_cam module / DC_SHOT overflow

Dear all,

I noticed an issue with the DC_SHOT photo number increment: photo number is okay until 255 photos have been taken, then it sticks to 255 in the DC_SHOT message.

I think we should increase the default value of DC_IMAGE_BUFFER (which is 255) in dc.h (Digital_cam module).

dc.c:

  if (dc_buffer < DC_IMAGE_BUFFER) {

    dc_buffer++;

    dc_photo_nr++;

    photo_nr = dc_photo_nr;

  }

Do you agree with that ? 

Regards,

Mitchell
