BME688 development kit firmware compilation issue

[fritz]

Hallo,

trying to compile firmware for the 8x dev kit as described in:

https://github.com/BoschSensortec/Bosch-BSEC2-Library/blob/master/examples/bme68x_demo_sample/Quick_...

but running in the compilation issue:   

    Sketch uses 1375781 bytes (104%) of program storage space. Maximum is 1310720 bytes.

    Global variables use 62800 bytes (19%) of dynamic memory, leaving 264880 bytes for local variables. Maximum is 327680 bytes.
    Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
    Error compiling for board Adafruit ESP32 Feather.

Obviously, we are running out of the available HW resources.

Any suggestions?

Hi fritz, 

Did you try to use our recommend version of library, not latest library. 

Latest libraries have more size, and it causes out of size issue. 

Thank you.

Hello Minhwan,

yes, I've used the recomended versions of the libraries as mentioned on the projects GIT readme page:

• ArduinoJson (tested for 6.19.4 by Benoit Blanchon)

• RTClib (tested for 2.0.3 by Adafruit)

• SdFat (tested for 2.1.2 by Bill Greiman)

and ended up with 104% of program storage space.

Sketch uses 1375781 bytes (104%) of program storage space.

There is only one newer version of mentioned libs available: RTClib verson 2.1.1.
Using this doesn't contribute to the overall program size significantly: +112 bytes

Sketch uses 1375893 bytes (104%) of program storage space.

BR's,

Hi Fritz, 

Then, it should work. 

Could you check which board did you set? 

It should be "Adafruit ESP32 Feather" in ESP32 Arduino. 

Thank you.

Hello,

yes, "Adafruit ESP32 Feather" board is selected as a target platform.
