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):
setup_all_sensors True None 0x1 False 4384 3280 write_sensor_i2c 0 1 0 0x31c08000 # hispi timing write_sensor_i2c 0 1 0 0x030600b4 # pll multiplier write_sensor_i2c 0 1 0 0x31c68400 # hispi control status write_sensor_i2c 0 1 0 0x306e9280 # datapath select write_sensor_i2c 0 1 0 0x301a001c # reset and start streaming hispi_phases_adjust 0 write_sensor_i2c 0 1 0 0x301a001c # reset and start streaming setup_all_sensors True None 0x1 False 4384 3280 compressor_control all None None None None None 2 program_gamma all 0 0.57 0.04 write_sensor_i2c 0 1 0 0x3028000a # global gain write_sensor_i2c 0 1 0 0x302c000d # some gain write_sensor_i2c 0 1 0 0x302e0010 # some gain write_sensor_i2c 0 1 0 0x30120080 # coarse exposure jpeg_acquire_write #write_sensor_i2c 0 1 0 0x301a0018 # put to standby

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
