Hello, I would like to request some help for some students that work on an Altera Stratix EP1S25 developpement board. They try to deal with the Conversion Numeric/Analog , so they wrote programs on VHDL where they declare a bit vector with a certain value, and send it to the CNA to see the values on the output. But... no matter the value they use, they always have zero volt on the outputs However, I think they were very careful with the pins numbers assignements of the components on the board.
And it seems they have the same kind of problem with the CAN (receiving a simple voltage, and transfer it directly to the outputs via the Stratix).
Can someone please help them (and me, by the way ?). I'm just searching for some VHDL code to test the CNA and CAN conversions.
Many thanks, Regards, A. Abellard
