Subject: convert to LVCMOS33 as it should be for 3v3
X-Git-Url: http://git.rot13.org/?p=trilby-hat-fpga;a=commitdiff_plain;h=6481d028f829c99117bea6831e85c71c939ce0bf

convert to LVCMOS33 as it should be for 3v3

Original project seems to be using LVCMOS25 and I really
don't know why, since VCC is 3v3
