LIS2DW12TR weird artifacts (or maybe incorrect processing of data???) Hello,
I am working on interfacing with a LIS2DW12TR sensor over I2C. I currently am able to read/write registers, and am working on processing the data coming out of the fifo. I currently have the following:
int read_LIS2DW12TR_buffer(int x[32], int y[32], int z[32]) {
static const struct i2c_dt_spec dev_i2c = I2C_DT_SPEC_GET(I2C_NODE_LIS2DW12TR);
uint8_t reg = LIS2DW12_OUT_X_L; // Start reading from the X-axis low byte
uint8_t data[32 * 3]; // 32 samples, each with 3 axes (X, Y, Z)
int ret = i2c_write_read_dt(&dev_i2c, &reg, sizeof(reg), data, sizeof(data));
if (ret < 0) {
LOG_ERR("Failed to read from LIS2DW12TR sensor: %d", ret);
return ret;
}
// Process the data into x, y, z arrays
for (int i = 0; i < 32; i++) {
x[i] = (data[i * 3] | (data[i * 3 + 1] << 8)); // X-axis
y[i] = (data[i * 3 + 2] | (data[i * 3 + 3] << 8)); // Y-axis
z[i] = (data[i * 3 + 4] | (data[i * 3 + 5] << 8)); // Z-axis
}
// print first values for debugging
