Function Documentation

static void doApplicationWork216 ( struct TestDescription td,
u32  offset 
) [static]
int runSCM216 ( struct TestDescription td  ) 

runs the test SCM mode, ACQ216 only. PSEUDO-CODE:

  • (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)
  • (9) [optionally update the target address - else it gets overwritten]
