## Supported Boards
- Arty A7-35T (with two PMODs for microSD cards and VGA output)
- Nexys A7 (planned)
## Supported FPGA Boards
### Arty-A7-35T
At the moment, the only supported board is the Digilent Arty-A7-35T.
Two Pmods are used for a complete system:
- the Digilent MicroSD Pmod at the JA connector
- the Digilent VGA Pmod at the JB and JC connectors
As the Arty-A7-35T is no longer in production, it should be easy to
use the Arty-A7-100T instead, but this has not been tested yet.
Other boards under consideration are the Digilent Nexys-A7 and the Olimex GateMateA1-EVB.
## Pascal Language
- Wirth Pascal
