BME280 pressure reading wrong

[jlehman]

I am using the BME280 to get temp, pressure and humidity in demand mode 1/sec. I have over sampling for each parameter set to 1. Temp and humidity  work. The pressure should be around 1020 but comes back around 630. Sometimes I get the correct value but most of the  time it is stuck in the 630s. Any idea what I am doing wrong? I am using the 64 bit compensation functions from the data sheet.

Thanks

Found my problem.  The write function was using an uninitialized stack value, causing random values to be sent to the control registers of the BMS280.
