I did not program the FT232 but FT2232, maybe it sould be similar, it was like: -init libftdi and create context -connect to usb device to context -if you want to talk to specific context you need to create a context for this port (not quite sure if this is a feature or bug in libftdi) -set bitbang mode, select input/output mask and default state for outputs -set port pins / get port pins -close device/deinit libftdi There are few examples on this on libftdi svn repository. I have tried bitbang and MPSSE mode, however mpsse produces strange timintg, so I have to work more on my code - when its done I will share it to that repository :-) Best regards, Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
