The interface exists in both the Serializer firmware (see User Guide -> i2c), as well as in the Serializer .NET Library (see Example under Namespace.RoboticsConnection.Serializer.Sensors -> I2CDevice class).  So, you can use it from your own custom app, Hyperterm, or from the .NET library.

We added this so that customers wouldn't have to wait on us to add/improve I2C interfaces in the Serializer firmware and/or .NET library.  Also, because it's generic, we keep the size of the firmware down.

Best Regards,

In the Serializer user guide the sintaxis for de i2c command is:

i2c <r|w> <addr> [data]

where <addr > is de direction of the device.

I am not able to connect, so I have same questions;

1. When I want to read, have I to use the read direction of the device?

2. When I want to write I use the direction of the device, the direction of the register in the device that I want to write, and the data that I want to write in the register. How can I use the generic command to send the 3 parameters that I need (device direction, register direction and data to write in the register)?

Tank you very much

So, for the MD22 (with a default address of 0xB0 (176 decimal)), you send serial commands similar to these to control it.

       i2c w 176 [data bytes]     // To write data

       i2c r 176 [data bytes]      // To read data

Are you sending the bytes yourself over the serial port?  If you use the Serializer .NET Library, you can utilize the Generic I2C object within it, and control your MD22 with code similar to this:

There are also examples in the Serializer User Guide for sending commands over the serial port (like first example above), instead of using our Libraries.
