摘　　要：介绍了一种基于LabVIEW与FPGA的LED汉字显示屏,其利用LabVIEW软件灵活、简便地从计算机的汉字库中提取汉字字模并转换为供FPGA直接调用的十六进制字模数据。通过在LabVIEW中进行图像信息扫描的方式得到任意汉字的字模,然后经串口传递给FPGA控制显示汉字。该方法的字模由上位机生成,省去了建立字模库步骤,简化了显示过程,实用性较强。This paper presents a LED characters display based on LabVIEW and FPGA. By using the flexible LabVIEW software, it extracts Chinese characters from computer and converts them into hexadecimal font data which are directly adopted by FPGA. Through image scanning in LabVIEW information, the Chinese characters font can be got randomly. Then it transfers to the FPGA to control and display characters by a serial port. The word-model of this method is generated by PC generation, which saves the font library established steps, simplifies the display of practical stronger.
