Hello,
I am using Nexys 2 board and VHDL language, I've already designed the vga controller 640x480, the PS2 interface for the keyboard,i am using a RAM block with 12-bit address and 8-bit of data
and a font rom. I know that RAM does not support reset, i have a reset btn that resets the counters for the lines that i want to write the keyboard's characters. The problem is that by pressing the reset btn along with the counters i need to clear the previous characters from the display.
if i'am correct i need to send to the specific ram addresses the character 'space'.
...
...
any ideas how to clear the line of characters by pressing the bnt?
thanx

Code VHDL - [expand] 1 2 3 ram_addr_2 <= (pixel_y(9 downto 4)) & (pixel_x(8 downto 3)); -- the address that goes to the ram block rom_addr_out <= char_addr & row_addr; -- the font's address
