BME680 – Air quality sensor

[viki2000]

In Flowcode 7 there is a component for the BME280 Bosh sensor.
Now we have Flowcode 8 and Bosch has also a new sensor BME680, which adds air quality measurement.

On the link above, if you go at "Downloads" and then "Further application boards", there are enough examples and boards to be seen.

For example here is Adafruit breakout board with the BME680 sensor and also Arduino code:

Can you develop a component for the new BME680 sensor?

Hello,

I've made a start and got quite far but then looking at the Adafruit example code they are reading a number of "calibration" registers that are simply not mentioned at all in the device datasheet.

I'll park it for now and have another look when I have more time to try and understand what's required to get meaningful values out of the sensor. I might also take a look at the Arduino code for comparison. Aha no it uses the same Adafruit library

I do not know if noticed the links recommended by Bosh directly, where we can see different breakout boards and the afferent code/library. Maybe that helps to debug further:
1) Here is from BlueDot:
A) An example based on Arduino and Adafruit library:
https://www.bluedot.space/sensor-boards/bme680/
B) An example based on ESP8266:
https://www.bluedot.space/tutorials/air ... he-bme680/
In the middle of the page there is “Integrating the BSEC Library to the Arduino IDE” and you can download the library “BlueDot_BME680_ESP8266.zip”

2) Here is from MikroElektronika:

And the library is here:

3) Here is from Tindie:

At the bottom of the webpage ypu may see documentation and software/libarary.

It is now over 1 year…
Any chance to work on BME680 and have it as standard component in Flowcode?

[viki2000]

Now is 2 years later.
Is this sensor included now in Flowcode 9?

I wrote a basic component - see viewtopic.php?t=22246
There wasn't much interest so left as was - but should work on AVR or PiC (but not MCUs that use i2c transaction mode (Arm and ESP32 amongst others)
If there is interest I could alter it to use transactions.

Try it and see if you can get it to work
