New Tutorial – PWM outputs on Papilio FPGA

In this tutorial you will learn how to use the PWM outputs of your Papilio FPGA board. For this particular step-by-step article, we have connected a button LED Wing to Wing slot AL. Basically you will be able to write a sketch that uses a PWM on any pin.

We have only used 6 pins of the 48 available! Imagine what you could control with 48 pins…

You can create your own circuit according to your goals, but in this tutorial we use the pre-existing one.

Using the flex pins adds extra freedom to move around with the code.

This is a very easy to understand tutorial but yet it is powerful on its content. Make sure you don´t miss this and overall, watch the video and enjoy the blinking lights!

New Tutorial – Draw a circuit with Commodore 64 SID audio chip!

In our ongoing quest to make using an FPGA as simple as drawing up a schematic we have a new tutorial ready. Using the Papilio Schematic Library you can draw up a circuit that has a Commodore 64 SID chip connected to a ZPUino Soft Processor, without learning any VHDL or Verilog! Just drag and drop components like the SID chip, a DeltaSigma DAC, an audio splitter, and the hardware to connect it to your speakers.

Its fun and easy to do and just think of all the possibilities! What about multiple SID chips connected inside the FPGA without the need to tear apart old Commodore’s or do any soldering. The tools are now in your hands to make electronics on a chip designs using the Papilio FPGA board and the Papilio Schematic Library.

Check out the new tutorial over at the Gadget Factory Learn website. Or take a look at the full walkthrough video:

New Tutorial – Draw a soft processor with ten serial ports using Papilio Schematic Library.

Happy Friday, we have something new for you to take a look at over the weekend. Continuing on with our series of tutorials about the Papilio Schematic Library we have the next one ready. How to add an extra serial port to the ZPUino is a recurring question in the forums, so we thought we would take it to the extreme and show how to add ten serial ports to the ZPUino! Even better, since we use the Papilio Schematic Library we can just drag and drop them in the schematic editor, no VHDL necessary. So take some time to look at the new tutorial on the Gadget Factory Learn website.

There is also a walk-through video if you prefer to watch the process:
