[lsm303agr] How to get temperature sensor value correctly?

It is always 0 to get the value of OUT_TEMP_L_A (0Ch), OUT_TEMP_H_A (0Dh).Before reading OUT_TEMP_L_A (0Ch), OUT_TEMP_H_A (0Dh), check the values of TEMP_CFG_REG_A (1Fh), CTRL_REG4_A (23h) and STATUS_REG_AUX_A (07h) as bellow:TEMP_CFG_REG_A (1Fh): 0x...

LPS22HH not responding to pressure changes

I'm testing the LPS22HH on the MKI192-V1 eval board. At normal atmospheric pressure it reports about 1013 hPa, which is what I expect, and it fluctuates over time by a few hPa. It also reports a reasonable temperature value, so I know the I2C interfa...
