Description

Instructions on how to disable sensor driver and get images from image sensor (for MT9F002 sensor)


Instructions

pre (editing files on the boot SD card)

  • Remove 10389 board if installed (otherwise will have to rewrite eeprom)
  • To load bitstream for MT9F002 appropriate changes need to be made to:
    • (not necessary, can skip) device tree
set sensors to mt9f002 in elphel393-detect_sensors,sensors entry
    • /etc/elphel393/default_10389.xml for setup w/o 10389 or 10389's eeprom otherwise write MT9F002 as application
Application name must be already added to /usr/local/autocampars.php
  • Disable driver
root@elphel393~# touch /etc/elphel393/disable_driver
# then reboot

init

  • start python session:
root@elphel393~# cd /usr/local/verilog/; test_mcntrl.py @hargs-after
  • init (if the driver is not disabled the i2c writes will not work):

Example: other window sizes

  • Download and run mt9f002_window_generator.py
  • Then edit the code snippets for 1600x1200 according to the new window size
  • If getting raw sensor data 8-bit and 16-bit the membridge buffer is 4MB, so calculate accordingly:
for 8-bit : WxH < 4M
for 16-bit: WxH < 2M
If not then - the buffer is circular which will result in overwriting of the beginning of the image
