keyword=roll-out of new ADC18 code
At last I roll out the new version of the 18-bit ADC
software which is supposed to solve the problem of oversampling
and should have only one "bad" ADC18 in the start of the run
(unless there is system-wide deadtime, then there may be others).
The backup versions are happex3_ts_ok5.crl and hapAdcLib_ok2.c.
The boot scripts still setup the ADC18, but that's ignored
actually because the ADC18 is reset in download. (We should
leave this, however, in case we need to roll back.) I modified
the CRL so that there is a 4 sec pause after reset to let the
device settle. Then I program in download (but not in prestart).
This includes gain settings, pedestals, DAC pattern, etc.
The timing board is still setup in Prestart as before.
Took a few runs, so far looks ok. I will monitor it for the
next few days.
