Example of SPI Reading of Coefficients
These are MPL115A1 SPI commands to read coefficients, execute Pressure and Temperature conversions, and to read Pressure
and Temperature data. The sequence of the commands for the interaction is given as an example to operate the MPL115A1.
Utilizing this gathered data, an example of the calculating the Compensated Pressure reading is given in floating point notation.
SPI Commands (simplified for communication)
Command to Write “Convert Pressure and Temperature” = 0x24
Command to Read “Pressure ADC High byte” = 0x80
Command to Read “Pressure ADC Low byte” = 0x82
Command to Read “Temperature ADC High byte” = 0x84
Command to Read “Temperature ADC Low byte” = 0x86
Command to Read “Coefficient data byte 1 High byte” = 0x88
Read Coefficients:
[CS=0], [0x88], [0x00], [0x8A], [0x00], [0x8C], [0x00], [0x8E], [0x00], [0x90], [0x00], [0x92], [0x00], [0x94], [0x00], [0x96], [0x00],
[0x00], [CS=1]
Start Pressure and Temperature Conversion, Read raw Pressure:
[CS=0], [0x24], [0x00], [CS=1], [3 ms Delay]
[CS=0], [0x80], [0x00], [0x82], [0x00], [0x84], [0x00,] [0x86], [0x00], [0x00], [CS=1]
NOTE: Extra [0x00] at the end of each sequence to output the last data byte on the slave side of the SPI.
