I am testing a prototype of my project using PC LPT port which will finally be replaced with a 8051
a) Use a second lpt port (these cards for pc are cheaper) b) Use an i/o card for pc (you can use for another prototype later) c) Test a half project and then the other half (is a prototype) d) Make and depure the prototype on '51 device (If you use an ISP device you only need a few parts) |
