Nowadays, you may be fed up of Star Wars jokes, baits and so on. I am sorry, I could not resist the temptation.
Anyway, this time, at least, was not a joke nor a lie. Today´s article brings the real truth to you. If you want to build your own robot, as simple as you want it to be, the first step should be to learn about controlling a DC motor! Now it does not sound as funny as watching the results achieved by the Dark Side´s Army. You may be wrong because this tutorial is everything but boring.
Very easy to read, this step-by-step article presents all you need to learn to properly understand how to control a DC motor just with your FPGA (yes you can use your Papilio). All you need is outlined and well explained (the code needed is given…). There are also some easy to understand physics explanations so you will get to understand the real ins of this project.
Do not miss this tutorial and be ready to get hired by The Dark Side!
This tutorial shows, step-by-step, how to turn your Arduino UNO into a 6 channel SUMP.
This logic analyzer is able to sample signals with a speed varying between 4 MHz and 10 kHz. Best results are obtained below 1 MHz. Above this mark, there is too much of a lag between the trigger detection and the sample start.
Alex designs an HDMI Wing and a custom PCB that lets him connect his salvaged LVDS laptop monitor to the HDMI Wing on his Papilio Plus. Next we need to get this working on the soon to come Papilio Pro!
Finally! PCB goodness in them mails. Feels like xmas.
First off I assembled the super easy Papilio HDMI wing, You can see different views of it in the insets as well as how it fits on the Pap board. It is technically not an 8 bit wing nor a standard 16 bit wing but a kind of modified 16 bit wing as it straddles two 8 bit wing slots due to the requirement for differential pins. The row of 4 pins with the missing pin connects to power and ground, the next row of 8 pins connects to the standard 8 bit wing and finally the last row of 4 pins connects to the adjacent 8 bit wing’s pins to get to the differential pair’s other pins which are not available on any 8 bit wing alone.
NTSC/PAL TV and audio output using 14 resistors and a low pass audio filter. This design can be built in a couple minutes using parts from Radio Shack. Open Source VHDL code and EAGLE PCB design files are available.
