LPT to I2C SE Professional
LPT to I2C SE Professional is a general purpose I2C interface tool that allows a user to communicate with any I2C slave devices. LPT-to-I2C SE includes the LPT-based host adapter hardware and Windows based software that is compatible with Windows 98SE, ME, 2000, XP, XP64, Vista, and Vista64, and Windows 7.
The LPT to I2C SE I2C Interface adapter operates over an extended voltage range of 0.9V to 5.5V. We have also added one output and one input pin. These can be configured as general purpose input and output pins but we have also integrated the output to act as a trigger (Low, High, Pulse High, Pulse Low) within the LPT-to-I2C SE software and the I2C dll. The triggers are ideal for debugging purposes since they can be inserted into an i2c message and can trigger a scope at a specific point in the message.
The LPT to I2C Adapter has also has IO/trigger functions. Download a demonstration copy of the software. Note that the demo version does not install the device drivers so it is not functional. You can also download a copy of Software User’s Manual to see how simple it is to begin generating I2C messages.
The DLL contains over 35 functions; from low-level functions (WriteBit() and ReadBit()) to complex functions (I2CWriteArrayDB()). Users who need to test their devices/systems for all types of error conditions (for example, sending an incomplete byte) will find this tool extremely useful.
