    BME688 Parallel Mode Parameters

    BME688 Parallel Mode Parameters

    Hi!

    I'm working on a project involving an array of BME688 sensors and I can't use the provided BME68x API code. I'm currently having issues collecting the gas sensing data and was hoping someone could look over the parameters I'm using. Perhaps, I have an error in how I calculate or read my data. I collect data about every 100ms. I'm hoping to add more heater profiles once I get one working. Also, there is a significant current draw once I set the sensors to parallel mode. Thanks for any help!

    osrs_t = 0b001

    osrs_p = 0b010

    osrs_h = 0b100

    iir_filter = 0

    nb_conv = 0b001

    gas_wait_shared = 18

    gas_wait_0 = 20

    res_heat_0 = 193

    Hello cweaver,

    Could you directly run the example code and see the gas resistance value?

    I can't. I have an intermediary controller that helps communicate between a Raspberry Pi and 32 I2C buses.

    Hello cweaver,

    I couldn't understand how do you get sensor data as you couldn't run BME688 example code?
