How Building a DPLCM To Learn About FPGAs Turned To Be A Possible Business

First of all, yes, what is a DPLCM? At least I had to look this up. Now, I can tell you that DPLCM stands for Digital Audio Peak Level and Correlation Meter. At this point we have covered the most difficult part.

This tutorial is so well explained, the author even tells you why he started this project, that all you need is to follow along. The DPLCM from this design can display the correct value of a single audio sample because it considers each sample on an individual basis.

This design is composed of three modules: the I/O board, the FPGA and the LED board. All the schematics are provided as well as different options to consider before selecting the boards.

At the core of this project you´ll find the FPGA, for which you will need VHDL and also you can learn about the theory behind this peak level meter. The code is provided as well, in case you were wondering.

At the end we find the funny part. Some DIY instructions for those who like the smell of the solder rather than go online and buy the boards!

Oh, I almost forget. This guy is looking for collaborators for a possible commercialization, so be quick about reading the post and getting in touch if you want.
