I2C problems with communication

[miker1423]

Hello, I'm trying to use your project but I constantly getting errors, none of them make sense to me... Do you encountered such errors? and how you solved them?

One of the errors is the next one: "The system cannot find the file specified. Slave address was not acknowledged,", the strange part is that all the other commands executed successfully, that usually happens when I execute the "Display Off Command (0xAE)".
