Getting bogged down...

So my final class I'm taking for my Master's degree is underway and is absolutely killing my free time. I have translated all three of the tutorials over to the PIC architecture, but I still haven't updated the write-ups. Some will take a little longer than others (the first one is by far going to be the most work). If you guys really want the code, send an email to brennen *at* diyembedded *dot* com. Otherwise, I'll try my best to get those write ups done this week/weekend if I have a minute away from HW and the girlfriend :) .

PIC code now working

I have now translated the code for Tutorial 1 over to the PIC 18F452. Many of you may know that this chip has been replaced by the 18F4520, but the code should still work just fine with minor modifications. I have to finish the write-up, but hopefully I'll have it posted in the next couple of days for you PIC lovers who wanna get down with an nRF24L01.

nRF24L01 tutorials for PIC coming soon

Well, I'm finally trying to get the tutorials translated over to the PIC line of microcontrollers. I'm programming in Microchip's C18 C compiler with MPLAB. I will be doing my development on an 18F452 (which has been replaced by the 18F4520, but is still basically code-compatible). I currently have the delays, SPI, and UART all working, so now it's just a matter of time to in testing the nRF24L01 library to see if I can get that working, and then integrate the main programs. Hopefully that should get you not-so-32-bit-inclined people out there up to speed with the nRF24L01 library!

Edit: The tutorials have been completed and are linked at this post toward the bottom:

Considering an audio tutorial

If I can get some spare time in the next short while, I'm considering developing a tutorial that would implement a wireless audio transmitter using my normal hardware (LPC2148 and nRF24L01) with a couple of buffers. I would just be using the 2148's built-in A/D and D/A converters, so the quality probably wouldn't be that great. I think it would be a cool thing for you guys that dig audio (like me), and it may be a good place to get you started on moving up into nicer components (audio-spec ADCs and DACs). I'd love to hear your comments or suggestions!

Tutorial 3 completed and uploaded

OK, I have another one for you guys. This tutorial shows you how to use all 6 pipes on the 24L01 (the idea was actually prompted from some questions over in the Sparkfun forums). Check out the zip file here.
