Hi all, i'm currently working on spuuort for a few cards from ids-imaging (www.ids-imaging.de).
These are 1/2/4 Chips cards based on Bt878's. The have a few digital input/output pins for security applications. I have assigned the following card - number and defines for the card types: card 0x68 (106) IDS-Falcon ( 1 chip, no i/o pins ) card 0x69 (105) IDS Falcon Plus ( 1 chip, 8 I/O pins ) card 0x6a (106) IDS Falcon Duo ( 2 Chips, 12 Input/8 Output pins ) card 0x6b (107) IDS Falcon Quattro ( 4 Chips, 12 Input/8 Output pins ) card 0x6c (108) IDS Eagle ( 4 Chips, Sync generators, ? I/O pins ) or in C ;): #define BTTV_IDS_FALCON 0x68 #define BTTV_IDS_FALCON_PLUS 0x69 #define BTTV_IDS_FALCON_DUO 0x6a #define BTTV_IDS_FALCON_QUATTRO 0x6b #define BTTV_IDS_EAGLE2 0x6c I need some ioctl's for the I/O handling, and an ioctl for waiting on special events ( sync, some input ports etc. ). What do u think about the ioctls? Are they worth to use global ioctl's, or just private one's for this dirver? I think that there could be more cards which support digital I/O, and it would be nice to have a unique handling of them :). My suggestions is, that there should be the following ioctls for this: VIDIOC_IO_SETINPUTMASK (int mask) VIDIOC_IO_SETOUTPUTMASK (int mask) eventually the corresponding GET ioctls also :). for handling a mask of I/O pins, so we could take the other ioctl's always from bit 0 upwards ... VIDIOC_IO_SETOUTPUT ( int output ) VIDIOC_IO_GETINPUT ( int input ) for setting / getting the values of the pins. VIDIOC_WAITFOREVENT ( int event ) to wait for events. I need the following events (think these bit's should be or'ed together) : BIT_EVENT_ODDFIELD 0x01 BIT_EVENT_EVENFIELD 0x02 BIT_EVENT_FRAME 0x04 BIT_EVENT_INPUT 0x08 BIT_EVENT_OUTPUT 0x10 BIT_EVENT_GETSYNC 0x20 BIT_EVENT_LOSTSYNC 0x40 The last point is, i want to enable some filters on the bt848 - bt878. Are there currently ioctls for this? And last but not least, plz. help me because of the ioctl values - i'm a total newby in asigning these numbers :). What do u think about that?
