Oh yes!!! thank srsa_4c for obsolete set_blacklight.
Not much time to make a progress.
I try to fullfill
code_get.txt by ixus160 reference port. In
filewrite.c may be have some mistake. CHDKPTP can't remote shoot. It crash my ixus175 immediately.
I can take a RAW with 29MB file size but it's only save RAW by quick press shootfull and not save RAW by shoothalf+shootfull. Is it normal.
And try to turnoff LCD display by set_lcd_display. It's just turnoff LCD until next capture.
Regards.
