Hello all,

I'm a student, I need your help how make program to show input from keypad 4x4 to hyperterminal on PC using assembly program with microcontroller ATMega8535.

Best Regard,

 

That's easy, think about the logic first, will you use polling or interrupt

Gampang..mikir logikanya dulu aja..mw pake polling atw interup?
