Tutorial 2 uploaded finally

So I finally got the write-up and code all worked out for Tutorial 2. In this tutorial, we will be exploring Enhanced Shockburst. Check this one out if you want a more robust link! NOTE: You should read Tutorial 1 before you read Tutorial 2. Tutorial 2 builds of Tutorial 1 heavily and is nearly identical in software (less than 15 lines total). Tutorial 2 can be found here.

In case you couldn't get Tutorial 1 downloaded, try the link in the post below and it should be working now. If not, feel free to contact me at brennen *at* diyembedded *dot* com.

New 24L01 tutorial uploaded

I have finished up the next tutorial in the nRF24L01 series. This tutorial outlines the procedures necessary for getting a link up and running with the nRF24L01 chips. Since there are a PDF and and source code, I have created a zip file, which you can download here.

Tutorial 0 for the nRF24L01 uploaded

OK, so I got studious tonight and decided to finish up Tutorial 0 for the nRF24L01. It is basically just background on the 24L01 chip and my preferred breakout, the MiRF-v2 from Spark Fun. I tried to give information on every aspect of the chip I could, including helping to explain connections, setup, instructions, registers, etc. I also tried to give hints and help on snags that I have run into in the past using the chip. Check out this tutorial here.

Two more tutorials are coming, and they are pretty much intro tutorials to get a simple link going. In the first tutorial, I will show you how to take data from the serial port of your computer port and send it to a remote microcontroller over the RF link, and then have the remote microcontroller send it back to the PC. In the second tutorial, I take basically the same code, but add in some functionality for Enhanced Shockburst transmission/reception with auto-acknowledgement and -retransmit.

Making progress

Well, I have signed up for some webspace and a new domain name. The tutorials have been written and tested in software, but still require some documentation. I'm hoping to have them out by the end of the week. This site will be going under considerable renovation over the next little while until I get a design I really like.

Getting started...

Hey guys. I am starting this blog to show some people some of the projects I'm working on and maybe put in some tutorials along the way. Most of the posts will be concerning electronics, and in particular embedded systems. The first thing I am going to try to post are on Nordic's nRF24L01 wireless chips. Check back soon...
