#51181 - Need more I/Os |
Hi All,
Can any one here can guide me in designing hardware for a project. I have done my homework but since I don't have much experience, I am not able to decide. The requirement is that I need to connect 50 leds and 50 switches and I have planned to use AT89C51 uC, here is it better to use another microcontrollers for the scanning of the leds and switches or will it be better to use I/O expanding IC like the Philips PCA9555.
