Hi,
I am trying to capture data from the IIS3DWB sensor at its maximum rate and save it into a buffer of length 8192 (due to internal RAM limitations). I'm using SPI with DMA to interface with the sensor. However, I'm not able to capture the data correctly — the X-axis shows incorrect values, while the Y and Z axes remain constant. I tested with another sensor, but the issue persists. The FIFO is configured to stream mode. I haven't detected any buffer overflows. I'm attaching the code and a CSV file for reference.
SETTINGS: SPI clock-8MHz, iis3dwb stores data in FIFO in continuous mode with 26.67k ODR , 3-axis mode is used, timestamp batch to FIFO is on, BDU is on, 16G range mode is on, IRQ pin -not connected, using polling mode.
can anyone give me solution.
Thanks
