+#!/usr/bin/env python

+'''
+  Generates window settings for driverless mode
+
+  For:
+      * mt9f002
+      * disabled sensor driver
+      * vact_delay=2, compressor_margin=0
+
+  Instructions:
+  * disable sensor driver (to enable back, remove 'disable_driver' file):
+    root@elphel393~# touch /etc/elphel393/disable_driver
+    reboot
+  * run python
+    root@elphel393~# cd /usr/local/verilog/; test_mcntrl.py @hargs-after
+  * from test_mcntrl.py session run
+  ** enable sensor, remove reset, adjust cable phases
