I2C Connectivity on SABRE

[Jochi119]

I wanted to run a basic Python script to communicate with a MPL3115A2 chip on the I2C3 line from the I.MX6Q. Can anyone give me a basic example on how to do this? I am running Ubuntu on the SABRE SDB.

Hi Joseph

suggest to look at attached file and below appnote with SW examples

AN4519 AN4519, Data Manipulation and Basic Settings of the MPL3115A2

Hello igor,

Sorry for my ignorance when it comes to this. I'm new at using this processor with Linux.  Do I need a .h file for this mpl3115.c file?  I see on the app note that they have sample code, but they refer to many functions that I don't see.  Example Below: Where can I find where IIC_Start() is defined?

  IICC_TX = 1; // Transmit Mode

  IIC_Start(); // Send Start

  IIC_CycleWrite(address); // Send IIC "Write" Address

  IIC_CycleWrite(reg); // Send Register

  IIC_CycleWrite(val); // Send Value

  IIC_Stop(); // Send Stop

Thanks,

Joseph
