I am doing a project on AUTOMATIC RAILWAY GATE SYSTEM.I want to make an led connected to a pin of port P2 of 8051 to light up when a bit of port 1 is set.How to do that.Please help
"to light up when a bit of port 1 is set"
It is often better to do the reverse - lots of processors have stronger sink than source capabilities.
But everyone know that if you are doing a project on AUTOMATIC RAILWAY GATE SYSTEM, then you need special extra care about how that LED is driven.
There is no similarity in the LED driving compared to just a stupid Blinky application. So obviously, it is important to find one or more web forum to collect enough help about this delicate process.
what help do you need? someone to write the code for you?
