SPIETBOX
(SPI Encodeur ToolBox)
Description
SPIETBOX* is a board developped around an FPGA SPARTAN-3 in order to
processing TTL and SSI encoders.
The board is design to work in stand alone or connected to a
SPICONTROLLER* through the SPI
interface.
Features:
- > 4 Output TTL
- > 1 TTL input 50 Ohms
- > 2 Soleil standard encoder input
- > 2 Soleil standard encoder output
- > Auxiliary port: 4TTL Output / 4 TTL Input
- > Power supply led
- > Status led
- > Reset push buton
- > 8 Switch: Board configuration
At the moment it can embed the following process:
* Adding 2 TTL Encoders (For eccentricity compensation of a mechanical
axis
* Level Conversion RS422 to TTL
* Duplicate encoder signal
* Triggers generation from encoder signal
* Protocol transfer
Quadrature to PULSE and DIR signals
SSI 12 Bits to SSI 25 Bits (ControlBox)
