Thanks for your reply. The code you listed is similar to what I have been running with the single thermocouple amplifier, however with the multiplexer, the code I listed isnt working as expected. Data is writing to the SD file but all values are 0.00 =(
This is probably because the values are 0.00. The only fileprint I see is floatTemp and the only time I see it assigned anything is on an "else" line, so who knows if the loop ever gets there? While I understood the end result is float, it is not clear that you are printing the same data to both destinations, or even if that is your intention. Right now, it looks like it isn't Clearly, there is nothing wrong with the SD or the recording process, and if you can see what you expect to see on the monitor, there can't be anything seriously wrong.
It would help if all the serial prints were brought together, followed by all the fileprints.
Your code to name the file by todays date can also be done with the sprintf function as follows.....
I thought you had a problem with date as filename. I think I have seen that code before but I have never tried it.
