I2C Driver

[RomanLehmann]

Where i can get a I2C-Driver for the i.mx53 QSB?

[RomanLehmann]

Is it possible to send something to the VGA I2C Bus like this: echo "Test" > ttyS0 But instead of ttyS0 to use the VGA I2C. If it would work like this it would enough for me. I just want to send some bits over the VGA-Port and to see this with my I2C tracer. Anyone a Idea?

I have a USB to I2C Tracer http://www.avitresearch.co.uk/i2c_bus_products.htm Now I wont to send something over the I2C-Bus at the VGA Port and to see with the Tracer if there is comes the same Massage that I send.

The installation and usage procedure are in the link I sent you earlier.

I haven´t understood your last question regarding I2C and VGA port.

Can you tell me how to install and to use this tool or were i can find a instruction.

An other question is.

How can I send something over the I2C-Bus so that I can measure the signal on the VGA-Port?

If you use a FSL kernel the I2C driver is located at:

drivers/i2c/busses/mxc_i2c.c

On a mainline kernel the I2C driver is located at:

drivers/i2c/busses/i2c-imx.c

You can use this i2c utility in userspace to test I2C:

My Job is to test the I2C-Bus. 

I just want to send something over the I2C Bus and measuring the signals with an oscilloscope. I need to do this for my final examination. But at the time i don't know how to do this.

Maybe you got an Idea.
