PIC chips are they interchangable?
looking at the 18F4520 and the 18F452
both look basically the same but the 4520 has an internal osc up to 32mhz (pretty sure as I am newbi at this)
ordered samples from Microchip to try out.
working on flow charts as to the operation of the air cannon data acquisition.
two IR sensors for the muzzle velocity measurements
two slot interrupters (wind speed and wind direction)
air chamber pressure (on Ebay I scored an expensive pressure transducer for $18.50 including shipping)
Called manfacture and the unit DSY-150 sells for $200+
unit is brand new, never used. just hope it works.
locating different code snippets to try out.
One question about LCD interfacing= ordered several 16 x 2 as well as 20x4.
can I use the same LCD.bas to operate either??
I need to research this aspect of project.
