I2C Connectivity on SABRE

Jochi119 — Fri, 03 Apr 2015 03:16:54 GMT

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.

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
