Hello there

I have task to complete urgently.. and i am looking for codes for PIC16F628... If you have or if you come across the codes for the following task below! please forward it!

TASk:

By pressing SW1, user starts the operation of the program. It waits until SW1 is released by the user, and generates a random number RND in the range of 0..7 and displays it using LD3, LD2 and LD1 (this action would normally hidden from the user,or be used for an electronic dice) for 0.5s. The program then switches LD3, LD2 and LD1 off, and switches LD4 on for 0.5 + RND*0.2s. After that it measures time after which the user presses SW2, and displays the result using all the LEDs with the resolution of 10ms (or all LEDs if the time was over 1s)

The preipheral program must use TMR0 to generate Pricise 1ms delay instead of the program provided.
The interrupt program must set LD6 on when TMR0 interrupt occurs.
The Question: Why you may want to use your program instead of the program provided.

Thanks plenty!

 

Presumably these are homework assignments, you need to show what you have done and where you are having problems, before you will get much help. You will find a pseudo random generator here:

By the way, do you want the code in C or assembler. Just name your preferred coding language. And the full All About Circuits community will be at your full disposable

 

i am having a problem with the whole stuff indeed

@t06afre- would wish for the code in assembler...
