  • ok I haven’t submitted code in github but there is always a first time. Currently my computer where the code resides is down. So once it is up I will submit some.

  • ok now I think I understand the problem. the Teensy3.1 int type are 4 bytes so I changed the int and unsigned int to int16_t and uint16_t. I have made the changes and testing further. I can share once I am done testing, let me know.

  • Well I will keep looking since I know one problem is the double type is different in the Teensy 3.1 than on the Uno etc. which really is equivalent to float for Uno’s etc. I will run your code on Teensy with the debug print statements turned on. It may be in the calibration routines.

  • I purchased one of these recently and they work fine. I hooked it up and used with Arduino UNO and everything seemed reasonable using the SFE_BMP180 library. but when I tried the same code on a Teensy 3.1 I get completely out of range values for all the parameters read. Yet I can use a library for the BMP85 by http://www.i2cdevlib.com/devices/bmp085#source and get good results. trying to figure what could be different. between the Teensy and the UNO that give such drastically different results using your code library any thoughts?

  • I download the software for this and played with it in demo mode. I also did the same with the Salea Logic system. Prefer the logic interface on the Salea and the MSO19 logic levels are limited to 3.3volts and below so if using a PIC at higher voltages would be a problem.

No public wish lists :(
