Part Number:LMP91000
I am using the LMP91000EVM connected to a Raspberry Pi microcontroller, to read H2S gas concentration. This is for a senior design project at LeTourneau University.
I have successfully set the I2C registers to configure the board, and I have read the SPI output from the board successfully to the Pi. At the bottom of this email is what I am reading as the output from the board.
I am unsure how to interpret this data, as it seems to typically be interpreted by the LMP9xxxx Sensor AFE Development Sofware/Hardware Platform on a laptop. However, since I am using the Pi to read the data directly, I am curious how to interpret the data. Is the output a hexadecimal code, representing concentration? If not, what processing is done to the SPI output of the LMP91000EVM to calculate concentration?
Thank you, and I look forward to hearing from you soon.
Example output:

[2, '\x00N']
[2, '\x00K']
[2, '\x00G']
[2, '\x00G']
[2, '\x00J']
