BMI270 initialization without config file

[ReseD]

Hello,

I just would like to be sure that is it possible to read the raw acceleration data from the sensor via SPI using drdy interrupt without uploading the config file shown in here: https://github.com/BoschSensortec/BMI270-Sensor-API/blob/master/bmi270.c ?

The issue is that the file wastes my limited memory.

I really would like to get an answer to this question, too, as we have the BMI270 connected to a very small PIC and 8kBytes is huge in this case. So any updates?

regards,

Martin

Update: tried Initialisation of sensor as described in Quick Start Guide of datasheet, just without download of Config File. Result is, that sensor does not put out any acceleration data. So seems the sensor does not work without download of config file. Please correct me, if I am wrong.

Hi guys,

The BMI270 must be loaded with firmware. For your application, you can use the BMI270 Maximum FIFO version(https://github.com/boschsensortec/BMI270-Sensor-API/blob/master/bmi270_maximum_fifo.c) which has minimum firmware.

Hi,

The sensor generates drdy interrupts with the minimum firmware. I didn't check the acceleration data yet, but hopefully it is also okay

有没有其他方法可以减少内存使用量？
