Hello ST Friends,
Here we are using H3LIS331DL in our product, using SPI interface. Below is the schematic.
and related code is below.
/* Check device ID */
static uint8_t whoamI, tData;
whoamI = 0;
h3lis331dl_device_id_get(&dev_ctx_xl, &whoamI);
user_printf("\r\nh3lis331dl whoamI: 0x%x\r\n", whoamI);
//REG1
tData = 0x27; //0010 0111

//REG2
tData = 0x00; //0000 0000

static uint8_t tx_buffer[64];

user_printf("ACC: %s\r\n", tx_buffer);
}
and below is the UART output, seems the register are all configured successfully.

But the ACC XYZ result seems abnormal.
we also captured the waveform as below.
WhoAmI read out.
REG config.
XYZ read out.
And we just put the board steady on the table, but the XYZ vaule is abnormal in this condition.
Do you have any suggestion on this, thank you.
YAN.
