Greetings all. I'm hoping you can help me. I'm pulling my hair out at the
lack of documentation for the TS-ADC24. I'm using the board with a TS-5400 (I
know this group is for TS-7000 series but I don't know where else to turn!!).
I've managed to make some progress despite the frustrating lack of supporting
documentation. I figured it likely that you all might have some experience
with this board and could help me figure it out...
First of all, nowhere in the "Getting Started" sheet provided by TS, does it
explain which channels the removable screw terminals are associated with.
They're labeled a1-a4 and b1-b4 on each side. Any ideas?
Secondly, in the doc, for the ADCCFG register I have 4 choices for Global
Analog Input Range and they are 0 to +Vref, 0 to +2Vref, 0 to +2Vref, and 0 to
+2Vref. But it seems to be that really is just two options! What is the
difference between the 3 0 to +2Vref options? I want the input range to be 0
to 5v.
The biggest issue I'm having is converting the data I get from the ADC FIFO to
a voltage reading. When I connect one of the channels to a 0v, I never get a 0
reading. I've seen a few comments that the data may be in two's complement
format or some other non-normal format. Any suggestions from this?
Thank you VERY much for any help you can give and/or point me towards.
Lee
