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.
Solved! Go to Solution.
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?
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.
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.
