Use of the VL53L0X with the nucleo-H7A3ZI-Q ( STM32H7A3ZIT6QU)

[Dg.1]

For a project i need to add the sensor VL53L0X to a program, i've found the Library for the sensor ( STSW-IMG005 ) i can compil the program with no error , but don't work , i'm pretty sure it's from the adaptation from the library to my STM32, if you have a similar case or can help me it will be appreciated !

Hi Associate

I suspect it was due to I2C function was not ported correctly, you can use below code do a I2C read/write function test to see if the I2C link is working fine. 

// . byte read/write test

VL53L0X_write_byte(0x52, 0x04, 0x5A);

VL53L0X_read_byte(0x52, 0x04, &byteData);

if( 0x5A != byteData )

{

// error

}

// . word read/write test

VL53L0X_write_word(0x52, 0x04, 0x5AA5);

VL53L0X_read_word(0x52, 0x04, &wordData);

if( 0x5AA5 != wordData ) // cut 1.1

{

// error

}

// . dword read/write test

VL53L0X_write_dword(0x52, 0x04, 0x5AA5AA55);

VL53L0X_read_dword(0x52, 0x04, &dwordData);

if( 0x5AA5AA55 != dwordData )

{

// error

}
