LED矩阵显示器代替LCD显示器

嗨比安卡，
MAX 6952是一款有趣的芯片，可驱动多达四个LED矩阵器件。
您可以将其接线并通过S3E Starter板右下侧的小型6针连接器进行连接。
它仅使用简单的3线接口。
也许您需要为LED添加外部电源。
另一种解决方案是根本不使用这样的控制器。
你有一个可以完成这项工作的FPGA。
;-)
但是你需要更多的针脚。
Digilent为FX2连接器提供廉价的开发扩展板。
如有必要，将显示器和一些线路驱动器放在上面，然后就完成了。
对于第一种解决方案，您需要实现一些3线接口和一些控制FSM以使MAX的寄存器正确编程。
也许Picoblaze会很有用。
对于第二种解决方案，您还可以考虑使用Picoblaze来提高灵活性，但也可以使用一些专用逻辑。
这取决于您希望使用的其他硬件的接口类型。 
如果您要实施秒表教程，那么根据本教程的要求模拟7段兼容端口会很不错。
但是，恕我直言，如果你设法完成上述任何一种解决方案，你就不需要再做教程了。
那时你已经超越了那个。 
有一个很好的综合

Hi Bianka,
The MAX 6952 is an interesting chip, which can drive up to four LED matrix devices.
You can wire it up and connect it via the small 6 pin connectors on the lower right side of the S3E Starter board.
It uses only a simple 3-wire interface. Maybe you ned to add an external power source for the LEDs.
 
Another solution would be not to use such a controller at all. You have an FPGA that can do the job. ;-)
But then you need much more pins. Digilent offers a cheap development expansion Board for the FX2 connector.
Put the displays on it and some line drivers if necessary, and you're done.
 
For the first solution you need to implement some 3-wire Interface plus some controlling FSM to get the registers of the MAX programmed right.
Maybe a Picoblaze would be useful.
 
For the second solution, you can also consider to use a Picoblaze for flexibility, but some dedicated logic would do it as well.
It depends on the kind of interface to the rest of your hardware you wish to use.
 
If you are going to implement the stopwatch tutorial it would be nice to have emulated 7-segment compatible ports as required by the tutorial.
But,IMHO, if you manage to finish either of the above solutions there's no need for you to do the tutorial anymore. At that time you are already beyond that.
   
 Have a nice synthesis

您是在谈论7段LED还是矩阵LED显示屏？
如果您正在寻找仅限数字显示器，例如便宜的20世纪80年代数字手表或时钟，那么谷歌“七段显示器vhdl”，你应该被淹没的例子。
这是Spartan 3设计板上的一个例子。

Are you talking about a 7 segment LED or a matrix LED display? If you are looking for the numbers only display, like a cheap 1980s digital watch or clock, Then Google "seven segment display vhdl" and you should be inundated with examples.
here is an example on a Spartan 3 design board.
