基于FPGA器件的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,能很好地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,实用价值较高。 FPGA-based LED digital tube display interface, according to display requirements, the hardware binary code to other binary conversion output, without the need for MCU software control, fast, can be well used in high-speed measurement display. In addition, the conversion of A / D sample value to voltage value is completed by the hardware circuit built in the FPGA, eliminating the need of look-up table, which can greatly save hardware resource overhead, simple design and high practical value.
