I2C of VL53L1

[vishnusf]

HI,

I am using VL53L1 sat board, can i configure I2C of the sensor to 1MHz? How should i do it? Could u please guide me on this matter?

Thank you

First we have two VL53L1 parts, and they are sligthly different as to which code they run. 

But either way when you download the API code, there will be examples. 

In main.c of the examples there is a bit of code:

* I2C1 init function */

static void MX_I2C1_Init(void)

{

  hi2c1.Instance = I2C1;

  hi2c1.Init.ClockSpeed = 100000;

  hi2c1.Init.DutyCycle = I2C_DUTYCYCLE_2;

  hi2c1.Init.OwnAddress1 = 0;

  hi2c1.Init.AddressingMode = I2C_ADDRESSINGMODE_7BIT;

  hi2c1.Init.DualAddressMode = I2C_DUALADDRESS_DISABLE;

  hi2c1.Init.OwnAddress2 = 0;

  hi2c1.Init.GeneralCallMode = I2C_GENERALCALL_DISABLE;

  hi2c1.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE;

  if (HAL_I2C_Init(&hi2c1) != HAL_OK)

  {

    Error_Handler();

  }

}

Just change that:

hi2c1.Init.ClockSpeed = 100000;

to:

hi2c1.Init.ClockSpeed = 1000000;

It's just the one line.
