![]() I am sure my keyboard controller works fine, as I tried it outindividually, shifter looks fine as well( I also tried this one on FPGA but without slowing the clock down, but nevertheless I was able to see the last scancode I entered), I haven't thought of any way/method to try out 7 segment controller, but that seems fine too. ![]() I am thinking that I have problems with clock, but seeing nothing on the display makes me think some part of the device is malfunctioning. I defined an 64bit std_logic_vector that can hold up to 8 scancodes, and then parsed the 4 MSBmost bytes of this vector, and directed them to seven segment controller, that muxes the inputs and decides which seven segment will be enabled. Now it is properly compiling and the RTL schematic seems true, but unfortunately I used a rather non-innovative way to shift the scancodes. Actually I am seeing digits on physical display (BASYS2 FPGA) and it is shifting as well, but I can not see them together, the last key I pressed is shown on display. Seven Segment Font Free for Personal Use PREVIEW DOWNLOAD :: Font Characters :: Font Files :: Font Info :: Font Preview Use the text generator tool below to preview Seven Segment font, and create appealing text graphics with different colors and hundreds of text effects. I can not resolve the problemĪfter deciding VHDL is having a hard time shifting indexes of arrays, I decided to change my shifter module. Seven Segment Decoder is a component that converts scancodes to gtoa (SEGMENTS). I am near to end in my project but stuck at some point.
