I would like to know how to configure RCC on my evaluation Board STM32L552E-EV.

[DYann.1]

I connect my I2C but when I connect an oscilloscope I have nothing on the clock signal. So probably I misconfigured my clock. Could you give me the information? Thanks in advance.

In this picture below I've a warning, do you know how to remove this warning please ?

Thank you for your helps.

I'll try it tomorrow. Thank you for your patience.

Hello,

I come back again, after having listened to your advice, I do not encounter any warnings or errors.

After, this step how can I check if my clock is running correctly on my evaluation board? For example, can I test the HAL delay function ?

I just to check this step before continuing to configure the I2C and then SAI.

Thank you for your helps

I also configure I2C and no warning and no errors.

After configuring the RCC, I2C and SAI I still have an error at the I2C level

 

Something is wrong but I don't know where it could come from

Transmits in master mode an amount of data in blocking mode:

HAL_I2C_Master_Transmit(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t *pData, uint16_t Size,uint32_t Timeout)

• hi2c Pointer to a I2C_HandleTypeDef structure that contains the configuration information for the specified I2C.
• DevAddress Target device address: The device 7 bits address value in datasheet must be shifted to the left before calling the interface
• pData Pointer to data buffer
• Size Amount of data to be sent
• Timeout Timeout duration

Hi,

All is correct after me. Do you have a working example for me to check the I2C communication ?

[Foued_KH]

You can refer to the I2C WIKI : Getting started with I2C - stm32mcu

Also  you can refer to the CubeFW to find the I2C examples : STM32Cube\Repository\STM32Cube_FW_L5_V1.4.0\Projects\

Hi,

I know what i's I2C and how does it work. Someting tells me this is the evaluation board clock configuration. The I2C clock is a derivative of the main clock, that why in my previous message I would like to test the function Delay.

I'll see the example but after me it does not exist on this evaluation board, let me check this information.

That confirm my thoughts :

[DYann.1]

I can locate the error inside the function

And the error is that this point

I don't know the signification of this error. Do you have any idea ?
