I2C library with the PIC18F46K22 and MCP4728

[Goblin039]

Hello, I am trying to use I2C library with the PIC18F46K22 and MCP4728, but it isn't work
I need to use Multi-Write Command.


I2C2_Init(100000) ;
I2C2_Start() ; // Start returns 0, no error
I2C2_Wr(0xC0) ; // Send Address, returns 2 - error
I2C2_Wr(0x50) ; // Send Command Multi-Write, chanell A, update out, returns 2 - error
I2C2_Wr(0x0F) ; // Send Command + Data, returns 2 - error
I2C2_Wr(0x00) ; // Send Data, returns 2 - error
I2C2_Stop() ;

What is my mistake?

With best regards, Goblin

Hi,

You can see how we implemented the communication between MCP4728 and MCU here :
