Based on one cyclone series FPGA produced by A ltera, an accurate schedule and a smi ple pe riphery a re ach ieved. T he key and UART con tro l the m ode of VGA signals output. T he LCD d isp lays the sty le of current signa.l The whole N ios system has exce llences of PLC and M CU. U sing FPGA to design a VGA interface can send the data directly onto the screen for d isp lay, which cuts down the process of PC, thus qu icken ing the speed of da ta pro cess and sav ing the expense of the hardwa re.
