Features:
- Easily connects to most I2C chips
- Prototyping area as well as TSSOP and SSOP pads
- 5 or 3.3 volt compatible
- Uses the ESPI 7474 circuit for reliable operation
The EI2C card must be paired with the "ei2c" peripheral and driver. The board includes an open-drain driver to accommodate the Spartan-3E which does not support open-drain outputs.
Hardware:
The schematic of the EI2C are shown below. The Eagle schematic and board
files are available here: ei2c.sch and here ei2c.brd.
