Topic: new project (Alphanumerical led screen) (Read 1 time) previous topic - next topic


Im thinking about ordering alphaNum character screens in bulk from China.
Does anyone have any recs.?
I see this as a tempting offer since its often half the price (ThanJameco).

I thought a pair of 595's per Char. Is sufficent (Them i order from Jameco, not that expencive.)

Why not lcd screens you ask?
Well i want to make a late 70's style homebrew pc using either pic\atmel.
Btw does anyone have any idea how to interface a keyboard with a mcu?

Kind regards.



The playground has several examples of keyboards/pads you can connect, including the PS2.


I would also use the PS2 keyboard. Althought I have never tried any of the ps2 libraries, I do want to. They apppear to make using the controller / keyboard very simple.

My website: http://www.harryrabbit.co.uk/electronics/home.html Up and running now! (Feel free to look round!) :D


If you want the real feel of a late 70's homebrew you should use a black and white TV for output. :)
