BME688 BSEC update problem

[Zaki13]

hello

i have developed a custom board using ATSAMD21G18A as MCU  and connected to a BME688 sensor.

i used the BSEC example provided by bosh for arduino and modified it to meet our MCU ( changes in SPI functions and delay ).

the problem is that when starting the application the bsecCallback function is called only once and after that no call is performed.

i used the cortexM0+ as library.

is there any modification to do to the Arduino example to avoid this problem ?

thanks.

Hello Zaki13,

Did you refer and run BSEC Arduino example on github?
https://github.com/BoschSensortec/BSEC-Arduino-library/tree/master/examples

hello

thanks for your message.

i fixed the problem, it was related to SPI timming.

now the BSEC callback is called during 53 seconds and then stops updating for about 1min40s , and starts again for 53 seconds.

is there any explation on this behaviour.

Regards.

Hi again

du to availlability of Microcontrollers this days, i want to use this one  : PIC32MM0128GPM036.

is this component compatible with one of the BSEC libraries provided.

Regards.
