The following example shows how to set up the card for Multiple Recording in standard mode.
The following example shows how to set up the card for Multiple Recording in FIFO mode.
spcm_dwSetParam_i32 (hDrv, SPC_CARDMODE, SPC_REC_STD_MULTI); // Enables Standard Multiple Recording
spcm_dwSetParam_i64 (hDrv, SPC_SEGMENTSIZE, 1024); // Set the segment size to 1024 samples
spcm_dwSetParam_i64 (hDrv, SPC_POSTTRIGGER, 768); // Set the posttrigger to 768 samples and therefore
// the pretrigger will be 256 samples
spcm_dwSetParam_i64 (hDrv, SPC_MEMSIZE, 4096); // Set the total memsize for recording to 4096 samples
// so that actually four segments will be recorded
spcm_dwSetParam_i32 (hDrv, SPC_TRIG_EXT0_MODE, SPC_TM_POS); // Set triggermode to ext. TTL mode (rising edge)
spcm_dwSetParam_i32 (hDrv, SPC_TRIG_ORMASK, SPC_TMASK_EXT0); // and enable it within the trigger OR-mask
spcm_dwSetParam_i32 (hDrv, SPC_CARDMODE, SPC_REC_FIFO_MULTI); // Enables FIFO Multiple Recording
spcm_dwSetParam_i64 (hDrv, SPC_SEGMENTSIZE, 2048); // Set the segment size to 2048 samples
spcm_dwSetParam_i64 (hDrv, SPC_POSTTRIGGER, 1920); // Set the posttrigger to 1920 samples and therefore
// the pretrigger will be 128 samples
spcm_dwSetParam_i64 (hDrv, SPC_LOOPS 256); // 256 segments will be recorded
spcm_dwSetParam_i32 (hDrv, SPC_TRIG_EXT0_MODE, SPC_TM_NEG); // Set triggermode to ext. TTL mode (falling edge)
spcm_dwSetParam_i32 (hDrv, SPC_TRIG_ORMASK, SPC_TMASK_EXT0); // and enable it within the trigger OR-mask
