The USB-ISS module is an enhanced version of our low cost USB-I2C module, offering additional functionality at the same low price. Communication to I2C, SPI and serial buses as well as digital I/O control and analog inputs.
Extra features over the USB-I2C are:
Support I2C at 20khz-1mhz
I2C + I/O
SPI mode
Serial mode (polled port)
I2C direct - build your own I2C sequence from discrete functions like I2C start
Bootloader - any future updates can be added
3.3v operation
Mounting holes on PCB
Examples:
Linux
Linux GCC - Various examples
Linux with Mono and Xbuild (C#) - Read the range and light values back from an SRF08
Mac
Xcode - Read the range and light values back from an SRF08
Microsoft Windows
