keyword=new ADC18 code issues
Two issues with the new ADC18 code
1) Sometimes (but it's not reproducible) the ADCs gets stuck
in a mode where base = peak = 0 forever. I may have fixed
this, however, by deleted adc18_softreset in partrig.
2) New kind of glitch: During one run the pedestal shifted
massively and the ADCs became noisier (fig 1). This affected
all the channels of both ADCs in ROC23, but none in ROC26
for this run. Still scratching my head on this one. It did
not happen with the old code.
To remind you, the new code has the repaired logic which (allegedly)
is better and fixes oversampling. I won't give up on it until
Monday, but we can roll back if necessary.
