Hi Dale, OK, thanks for the clarification. The first 2 cycles only gave a code of 0 hex. After that, it was fine. I connected a DC level to channel 0, and those first 2 reads now contain what looks...
View ArticleForum Post: RE: ADS8638: data invalid for first couple of reads, then OK
I forgot to ask - is the default channel sequencing mode at power up "auto" or "manual"? And if we are in "manual" mode, based on what you have written above, am I correct in thinking that if we want...
