Just a quick question with regards to executing some instructions quickly. I'm using the pa7i9600.icb file to control a couple of mini SSCs, and I need to move 6 servos as close to simultaneously as I can. My question : is it faster to write a (...)

(...) yes. this was omitted from the assem instrcts and i've added it now. (...) look at the parts list for things that are referred to as "xx-pin male header". these have a part number; e.g., J3, a 14-pin male header. look for J3 on the PCB (...)

(...) Look in an older edition of The Art of Electronics by Horowitz and Hill. They use the LM317 as an example voltage regulator, explain the resistor values, and provide a data sheet in the appendix. This is a very useful reference book for all (...)

Yes, I had a similar problem. I then downloaded the revised files and found "lib_hb.c" failing to load also. After opening it in a text editor, I found the same 'line feed' type of characters (square boxes). I deleted them and made sure that all the (...)

I received my HB expansion kit from Douglas Inc. (under $30 and fast delivery!). I've tried to gather as much documentation on its assembly. However, I have two questions: 1) The DOT on the resister pak's: Is that the end which goes in the SQUARE (...) (26 years ago, 27-Jan-99, to lugnet.robotics.handyboard)

(...) Use an LM317T adjustable voltage regulator and 2 resistors. If you can't find a data sheet on it on the net somewhere, someone should be able to give you the formulas for figuring out the resistors. Find national semiconductor on the net and (...)

Hi, Could *each* of the digital output pins on the Expansion Board be used as 9600 Baud Serial Output Drivers ? Could a higer baud rate be used with any of the digital output pins ? Could someone clever than me create the libraries and the (...) (26 years ago, 26-Jan-99, to lugnet.robotics.handyboard)
