ASM330LHHXG1 does not take the DRDY flag to high

[eds]

I am trying to get data from ASM330LLHXG1 so first, I decided to try the self test code provided by ST to see whether I can make the sensor work, until the reading of status register it was going okay but no matter how long I wait the status register data ready flag for both gyro, accelerometer, and temperature are all zero. The code is stuck at while(!drdy) :

/* Check device ID */

asm330lhhxg1_device_id_get(&dev_ctx, &whoamI);

if (whoamI != ASM330LHHXG1_ID)

while(1);

/* Restore default configuration */

asm330lhhxg1_reset_set(&dev_ctx, PROPERTY_ENABLE);

do {

asm330lhhxg1_reset_get(&dev_ctx, &rst);

} while (rst);

/* Disable I3C interface */

asm330lhhxg1_i3c_disable_set(&dev_ctx, ASM330LHHXG1_I3C_DISABLE);

/* Enable Block Data Update */

asm330lhhxg1_block_data_update_set(&dev_ctx, PROPERTY_ENABLE);

/* Accelerometer Self Test */

/* Set Output Data Rate */

asm330lhhxg1_xl_data_rate_set(&dev_ctx, ASM330LHHXG1_XL_ODR_52Hz);

/* Set full scale */

asm330lhhxg1_xl_full_scale_set(&dev_ctx, ASM330LHHXG1_4g);

/* Wait stable output */

platform_delay(100);

/* Check if new value available */

do {

asm330lhhxg1_xl_flag_data_ready_get(&dev_ctx, &drdy);

} while(!drdy);

Hi @eds ,

If you want to implement the self test you can start from our official example on Github.

Let me know if it works!
