Hi Huy,

Are you asking what calling those functions with an argument of 0x44 does?

Thanks,

Yes, why we must send 0x44 and data to I2C in function I2CWrite?

Hi Huy,

That seems to be the Data address for the LEDs.

Thanks,

Hi Gerardo,
Where we find this information? Have another address?
Thanks for your answer.

Hi Huy,

I'm going to have your question moved to a different forums as it's not a TI-RTOS question, they should be able to explain this further.

Thanks,
Gerardo
