Specifically with LPC2138, I want to convert the code written for 8051

berto

Hello friends, I need your help

have time programming code for 8051 (c51) in keil and have no problem

but now I would like to start with arm, specifically with LPC2138 and I want to convert the code I show is written for 8051

but I can not do start All I know is how to define ports and little else.

I swear I've tried but have not succeeded.

the code is for a led matrix display and Works fine

please can help me?

the arm is no attempt to use the uart

thank you very much

the code in 8051 is:

    

  1.   //crystal is 22-24MHz
    2. 

  2. //was made for Keil compiler
