Ok I'm on 2.9.5. I'll update. I figured that the module you wrote was low level stuff but apparently I don't know what does what. C > On Jun 30, 2016, at 7:34 PM, Paul W Panish wrote: > > It looks like Paul submitted my changes in v2.9p6. Support for the > MAX31850

It looks like Paul submitted my changes in v2.9p6. Support for the MAX31850 was added in v2.9p2. Not sure what you're saying beyond this, and I haven't worked with the scratchpad registers. When I modified this code I basically performed a dump of the data available in the ow_1820.c module to

In what rev were these made? I'm on 2.9 I believe and neither make sense. What is the possibility that scratchpad gets read wrong? I have no visibility into the code but the faults I am observing are suspect, considering everything reads fine using tmex. > On Jun 30, 2016, at 3:58 AM, Paul

Sure, sorry I can't be of more help at the moment. To be clear, with the changes I made, which were done empirically, I was able to read the hot junction thermocouple temperature using the "temperature" access string on the MAX31850 development board I had purchased. It also read properly

DS9490R yields similar results. This time only a ground short is observed. Again, this seemed to read fine into a DS9490R using the TMEX API through LabVIEW. Looking at the two datasheets, there is no way to avoid device-dependent code. There need to be three distinct values: temperature,
