VEEK MT - i2c_touch_config in VHDL

It might have something to do with the LED_test process not being synchronous. You put clock_50 in the senstivity list, but you didnt follow the template:

process(clk)
begin
  if rising_edge(clk) then
    --do sync stuff
  end if;
end process;

Thanks for your quick response.

did you testbench this?

No. I don't really know what i am supposed to test.
