基于FPGA器件设计的可以任意设定的LED数码管显示接口可根据显示需求,硬件实现二进制码到其他进制码的转换输出,无需MCU软件控制,速度快,能很好的应用于高速测量显示领域。另外,A/D采样值到电压值的转换,由FPGA内部构造的硬件电路计算完成,无需查表,可大大节省硬件资源开销,设计简单,具有很高的实用价值。 FPGA-based design of the device can be arbitrarily set the LED digital display interface can be based on the display requirements, the hardware binary code to other binary conversion output, without MCU software control, fast, and can be well applied to high-speed measurement display field. In addition, the A / D sampling value to the voltage conversion, completed by the hardware circuit built in FPGA completed without checking the table, which can greatly save the hardware resource overhead, simple design, with high practical value.
