Mapping of Pins on the Dagu Spider Motor Controller

I made a mapping of the Dagu Spider Motor Controller pins. The cells in red are what you see on the board itself. Other info has been placed adjacent to those cells for easy reference of functions, alternate names etc.

 

Curiously I am wondering if there is actually a typo mistake on the board with one of the pins being labelled as "TXD1/D1" when it should be "TXD0/D1" instead. Is that an error?

 

Please give feedback on the accuracy of the mapping.

Video Encoding with CS4954

Hi,

I have some new and interesting stuff to share. The attached photos demonstrate my progress with generating baseband video signals (CVBS or composite video) for wireless transmission (see my other blog posts). As I finally realised that video stream editing at 27MHz data rate (towards stereoscopic vision) is hardly possible with the Parallax Propeller, I turned over to hardware editing. In the first step I thought I should start with discrete logic IC's but a colleague of mine "persuaded" me to use an FPGA. Well, he was definitely right.


Note: You can follow some projects some of the time, but you cannot follow all the projects all the time.

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
