vl6180x is always busy in single shot reading mode

After sending 'single shot reading mode' command (sending 0x01 to register 0x0018), I check 'RESULT_INTERRUPT_STATUS_GPIO' register at 0x04F and always read 0x00 that means it is busy.

I replaced vl6180x with a new one but problem still continues.

I do not have any problem in reading/writing from/to vl6180x registers. Initial values are standard values given in application notes.

Anybody comments on this problem ?

thanks in advance

Hi Cem kar

I have the same problem.

Initialization and Defaul setting acording to app notes,,

Starting Single shot mode

Polling for INTERRUPT_STATUS_GPIO = 0x04

Logging RESULT_RANGE_STATUS

No data in result.

All communication in I2C is OK. I can write and read to alle registers.

All help is apriciated.

I have a problem reading /writing from vl6180x using i2c.

if(HAL_I2C_Master_Transmit(&hi2c1,0x52,0x00,1,100) ==HAL_OK){

HAL_GPIO_WritePin(GPIOC, GPIO_PIN_8, GPIO_PIN_SET);

HAL_Delay(10);

}

This don't set to GPIOC8.
