Stepper
Hamster puts together a nice tutorial with code about driving a stepper motor with an FPGA. Driving a stepper motor using an external driver board is a bit tricky when using a microcontroller. With an FPGA it is a piece of cake! via hamsterworks.co.nz

Direct Digital Synthesis (DDS) Explained by [Bil Herd]
Bil Herd, the designer of the Commodore 128, talks about DDS (Direct Digital Synthesis) on a CPLD. There is some excellent information here that is very applicable to the Papilio FPGA. Maybe we can even adopt this project to DesignLab. “One of the acronyms you may hear thrown around is DDS which stands for Direct…

Free E-Book: Adam Taylor’s MicroZed Chronicles
Free e-book for the ZYNQ FPGA, while this won’t help with the Papilio it is good information for those thinking about getting into the ZYNQ FPGA’s. This free e-book teaches all about working with the Zynq SoC FPGA, all the way from the “Hello World” basics to asymmetric multiprocessing and the addition of several real-time…

Cx: A New Language for Hardware Design & Verification
Here is another new language for high level hardware description. We haven’t used it but this article has a clear description of why a hardware description language that goes further then VHDL or Verilog is needed. via www.eetimes.com Cx (formerly C~) is a new language for hardware design and verification that is at an…

Hamster’s HDMI Input Project
Take a look at this forum project that Hamster is working on – HDMI input! Watch as he generates video pulls it into a Papilio, then converts it to VGA output. Very cool. 🙂 https://www.youtube.com/watch?v=AvHPYmEQb04 I hit a brick wall on this for a couple of days – it locked correctly but no HSYNC or…

Propeller 1 Open Source
This is a little bit of old news by now, but it’s still super cool. Parallax has open sourced their Propeller 1 Verilog code! This means you can have a Propeller 1 on your FPGA board. 🙂 The only downside is that it is quite large – in order to implement all 8 properller cores…
