Software customization and real-time debug
The STEVAL-MKI111V1 demonstration board can be fully adapted to the container the user
intends to test. The firmware included in the demonstration board kit is provided as open
source. The demonstration board can be connected to an ST debugging tool with SWIM
interface in order to read in real-time the signals coming from the MEMS sensor.
Pressure signal
The pressure read by the MEMS sensor is stored in a variable which is constantly updated
in an infinite loop. To avoid oscillations and reduce the error introduced by false readings,
the variable holds an average pressure value, which is obtained out of 8 raw readings
coming from the MEMS sensor. Pressure readings are expressed as absolute values.
Pressure signal: Average_Pressure
Temperature signal
The temperature read by the MEMS sensor is stored in a variable which is constantly
updated in an infinite loop. To avoid oscillations and reduce the error introduced by false
readings, the variable holds an average temperature value, which is obtained out of 8 raw
readings coming from the MEMS sensor. Temperature readings are expressed as 2’s
complement numbers.
Pressure signal: Average_Temperature
