  • Hi William, Thanks so much for confirming this. Ideally we could run in analog mode and read the voltage values from the z accel channel instead of an analog pin. I don't see where there's a single place in the firmware to do this, though showi…
  • FYI: An analog thermocouple amplifier (AD8495) worked best for this application, where the highest degree of temporal resolution is required.
  • Thanks again for your help. I'll let you know how it goes.
  • That's true. However, this particular application requires temperature (as a proxy for airflow) measurement from different locations within the nasal cavity. This might differ from chest strap output right after swallowing, which is the period we're…
  • Ok. Thanks William.
  • I'm going to try the way that involves a lot of work. Is there sample code on reading from and SPI device through the OpenBCI platform?
  • I noticed that, but the issue is that I need to position it in the nose to measure faint changes in respiration. The thermocouple is a good sensor for this purpose. I really appreciate your comments. Very useful.
  • I don't want a lot of work. Is there a way to get the temperature readings from the arduino into the data file collected by the Cyton? One possibility might be to use a DAC breakout on the Arduino and feed the voltage signal into an analog channe…
  • Thanks so much WIlliam. I'm using a Max31855 thermocouple-to-digital converter, which works well on my arduino. I can't quite get it to work on the Cyton board. The converter has the following pins, which I've connected to the Cyton board in thi…
