void appEnterLLC_SYNC_2VRFM ( void   ) 

set up LLCV2_INIT buffer and enter mode.

Buffer set up as 4K block at offset 0

  • this overwrites settings from initV2Stats(), initV2Stats is therefore redundant.

static u32 card_sync_2v_WaitDmaDone ( struct Card card  )  [static]
int runSYNC_2VRFM ( struct TestDescription td,
int  soft_clock 

runs the test SYNC_2V mode.


  • (1) Clear the latch timer
  • (2) Set a local memory target address and arm the capture
  • (3) Poll for counter running (hardware counter starts on external gate)
  • (4) Iterate for required number of samples:
  • (5) [optionally send a soft clock command] trigger an acquisition
  • (6) Wait for DMA Done - at this point data is available in target mem. A "real" control application is probably getting most of its calcs done here rather than simply polling
  • (7) [Get the latch (sample) and current uSec counters from the boards - only if interested]
  • (8) Check the process has not stopped (external gate high)
  • (b) write data to host side buffer(LLCV2_AO_HSBS)
  • (b.1) take the incoming value on feedback_channel and propagate to all DACS. default is to assume HAWG on DAC0 (so feedback_channel better be 0 !), but td->update_dacs makes a better test.
  • (b.15) special case where we are DRIVING the initial DAC signal from host side.
  • (b.2) simple feedforward case - just drive all DACS from AWG pattern.
