Connii – I2C Fast Mode Interface for USB, Single Master
Connii is a small, compact, easy-to-use solution for a PC driven I2C transmitter and receiver. The I2C interface works as an I2C single master device.
This singlemaster behaviour is the main difference between this product and Connii MM 2.0, which is a multimaster. If you expect your application to have more than one I2C master on one bus, or if there will be an I2C slave stretching the bus, Connii MM 2.0 is your choice.
The unit is connected to a PC via a standard USB port. Both I2C modes standard (100 kbit/s) and fast (400 kbit/s) can be selected as speed of operation. The device has two connectors – a standard USB plugin and a PS/2 connector for your I2C bus.
In case you are looking for a more sophisticated I2C USB interface please check Tracii XL 2.0, the sole I2C interface supporting the I2C high speed mode.
The product comes with the most advanced I2C software package on the market, it is featured by the telos I2C Framework and runs under the sophisticated I2C Studio. Labview VIs are included running different I2C modes.
All the software is for free, there are no hidden fees!
