Title: New to 8051 pls help!!!
Post by: double_agent on January 19, 2006, 12:16:25 am

Hello all,
    i am new to 8051 controllers.
 i hve couple of Q\'s
1. How to test if the controllers is working
    for Ex: i have loaded a program to turn on port 1
    p1.0 to p1.7

2. the main setup to run a 8051 chip
   a.Supply voltage (5v if i am not wrong)
   b.ICC supply current(50mA?)
3. Pull up resistor required to check the out put frm
   any port?  
and do i need to give a high on EA pin or the reset pin.
in order to run the circuit?

if any 1 can giv any inputs/ideas tat will do gud!

the best way to test a micro P is to write a program which generates a square-wave from one of pins; unlike 68hcxx, you don\'t need to mess with any data direction register. You don\'t need any pulll up/down resistor either. Use the power adaptor that came with 8051.
