ppm-grab#

PPM-grab can be used to store raw images on the MMC card that can be used with the virtual-cam for testing algorithms.

Setting Up PPM-grab:

  • You will need the following:

    • CMUcam3, with power and a serial cable

    • MMC or SD card

    • MMC/SD card reader on your PC

  • Format the Memory Card using the FAT filesystem

    • DO NOT USE FAT32 which is the Windows Default

  • Flash the ppm-grab.hex firmware file onto the CMUcam

    • Go to the cc3/projects/ppm-grab directory

    • Type “make” to build the application

  • Turn off your CMUcam3 and bring it to the area that you want to monitor

  • Insert the MMC card and turn the CMUcam3 on

    • After 1 second, press the button on the CMUcam3 to take a picture

    • Make sure the led toggles after each press

      • if the led doesn’t toggle, look at the serial output of the camera to see if an error is reported
