i2c

Litefire

sorry to sound hopeless, but i'm new starting out with i2c, and need a little help with my motor controller...

can someone give me some sample code to read and then to write to a register on this controller: http://www.robot-electronics.co.uk/htm/md23tech.htm?

I looked at some of the objects... but a lot of it just looks like gobbledygook cause i don't know what the terms mean.

Thanks for any help...

Have a look at the MCP23016Object.spin file in the I2C functions archive. This is a similar device that has a set of 8-bit registers addressable with an 8-bit register address.

Post a list of the terms you don't understand or what you think they mean and we'll try to explain them for you.

There is also a MD22 motor controller example - which I believe is similar to the MD23 from robot-electronics

On the robot-electronics examples page, I also have Javalin Stamp and there is basic stamp examples which might help.

Mike,
How/where can I find the <I2C funcions archive>

If you go to the Propeller page of the Parallax website, you'll see a link to the Propeller Object Exchange (ww1.parallax.com/Default.aspx?tabid=65). This is a library of contributions by Parallax and Propeller users including the I2C functions library which has the example I mentioned as well as others.
