|
*SPIETBOX** is a board developped around an FPGA SPARTAN-3 in order to
|
|
|
processing TTL and SSI encoders.
|
|
|
processing TTL and SSI encoders.
|
|
|
The board is design to work in stand alone or connected to a
|
|
|
*SPICONTROLLER** through the SPI interface.
|

|
|
The I/ of the board:
|
|
|
|
|
|
