Here is a breif overview, for those who are interested.
The finished project will consist of 3x7 segment led displays, 20x leds, a 16x2 lcd panel and 3 switches, a pic processor (16F628A) and a MAX7219 serial multiplexed display driver.
The basic operation of the circuit is as follows:
count the number of pulses on PIN A, display the result on the 7 SEG display
count the number of pulses on PIN B, display the result as a bargraph on leds,
add the pulses from pinA to the value stored in memory, display on lcd.
repeat indefinatly, if switch 1 is pressed, reset the count on lcd.
the finished design must have a connection, so that I can update the value stored in memory via a serial or parrallel port on my computer.
The finished board size will be approx 4" x 9", with cutouts around the perimiter, there are no slots ect in the board itself.
If this is still of any interest to either of you or to anyone else, could you give me so indication of the cost to design and build a couple of these as prototypes, and also how much to build 100 of them once the design is done. You need not supply the parts for loading the boards, eg lcd and leds ect. Just the boards would be fine.
Anyone who give me a rough cost for this project as well as some examples of other projects they have undertaken will recieve the full product specification.
Thanks In Advance

PS. Sorry about my way putting this, i am trying to describe my project without making it public knowledge as this would affect my patent application.
