#100449 - Back to basics
Responding to: ???'s previous message

I grew up on the basic stamp, which really limits what you should learn.

Yes, BASIC (or any other high-level language) shields you from the need to understand the details of the underlying architecture.

In Assembler, you are talking directly to the underlying architecture - it is essential that you understand the details!

I suggest that you need to set this project aside for a while, and spend some time reading the Tutorials here.

You will also need to download & read the documents commonly referred to as "the bible" for the 8051:

Chapter 1 - 80C51 Family Architecture:
http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf

Chapter 2 - 80C51 Family Programmer’s Guide and Instruction Set:
http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf

Chapter 3 - 80C51 Family Hardware Description:
http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf

These documents define the basics - you will also need to read the Datasheet for the particular chip you are using for specific details.

although if I want to make some LEDs flash I'm good.

You need to begin at the beginning - flashing LEDs is a very good place to start!

You need to lay foundations before you start building walls!
