Hello, I would like to make the Grove - 16 Channel PWM Driver (PCA9685) work with an STM32F429I-DISC1 board. Can you help me?

I would like to do this to control LED strips, however, I have a problem because no matter how hard I try using the HAL_I2C_Master, it doesn't work.

Do you find the solution? Because i have the same problem, i use a PCA9685 with the adress 0x7f, and the i2c connection don't work. I test my connection with the HAL status.
