I connect mpu6050 to i2c3 and make a project with stm32cube and enable i2c3.

but cant detect sensor. for(i=0 ; i<255 ; i++)     {         test = HAL_I2C_IsDeviceReady(&hi2c3,i,10,100);         if(test == HAL_OK)             break;     } return always HAL_BUSY  my board is stm32f4discovery #i-can''t-help-you-with-that

please answer me

Do you think you've provided enough circuit or software details for anyone to replicate your experiment?

my answer is why when i want to read or write from i2c bus , all HAL_I2c_...  function return me HAL_BUSY.

I enable I2c 3 in stm32f4cube and make project in keil. I connect SDA and SCL pin to MPU6050 sensor. I test this hardware with another program an it work property. My problem in HAL_DRIVER

Hi! Try to add some delay between your cycles.

It is from function ''HAL_I2C_IsDeviceReady'' description:

This function is used with Memory devices.

Posted on January 19, 2015 at 10:19 I try delay . but not work. I see a simple code to use sensor with Hal memory write function. This program must be check all i2c address on port and return if exist
