-Epimetheus (or Epi for short) is a general purpose input/output board that sits on the Atlas bus.

 Early days as yet but the following block diagram explains the concept:
 The design will use a CPLD  written by Steve KA6S consisting of an I2C slave, I2C master (from OpenCores), and a micro-coded Wishbone Master that is capable of sending messages over the I2C Master.

 The I2C Slave is used to program all on-chip resources including uploading the Wishbone Master Microcode, and initializing the device control registers and I2C master.

 Any ideas/suggestions/requests for other I/O that we can put on the board?

-The design will use a CPLD that contains an I2C slave written by Steve KA6S. This will respond to multiple I2C address ranges so all the inputs and outputs can be individually addressed.

 The use of a CPLD rather than a uP should result in an EMC quieter solution. The 200MHz cross point switch is intended for use with VHF/UHF/SHF transverters so that the various IFs can be switched around. The switches are intended to handle a few 10?s of mW so can be used to switch low level HF/2m etc drive around.
