Note to self: After timers tutorial, make clock source tutorial.

| These Zigbee devices are cool things. There must be some professional tutorial on this community on the integration of these devices with AVR's USART. |

A tutorial on the evils of interrupts and pre-emptive task switching - such topics like:
how interrupts work
sharing variables
atomic access
task switching - co-operative vs pre-emptive
time and time again, both on this forum and many others I see people using interrupts without knowing the pitfalls of using them. Non atomic variable accessing etc.
Dean, your writing style has improved a lot. Very readable and a lot more factual. It might help to include some references for your information so that people don't think you're pulling the info out of your bum! All goes towards separating fact from opinion. |

A tutorial on ZigBee or some other wireless communications would be very helpful for us beginners that have been soaking up the existing tutorials.javascript:emoticon(' ')

I'd love a tutorial on writing a Makefile, specifically for AVRs and tying in avr-dude commands.
I'd love to have an open alternative to AVR Studio for portability between all my machines. |

To be fair there's nothing particular AVR specific about writing GNU Make Makefile's if you just type "GNU Make tutorial" into Google you'll get loads of hits (23,200 in fact). These ones come near the top of the list:
http://www.metalshell.com/view/tutorial/120/
http://www.cs.utah.edu/dept/old/texinfo ... e_toc.html
As for avrdude - the user manual covers pretty much everything you need.
By the way some people have adapted Eclipse for use with AVR as a cross-platform IDE. |

What kind of interrupts? I know that there are tutorials on both UART and ADC interrupts already - maybe others too?
EDIT: A search for "interrupt" in Tutorial Forum currently hits 47 threads including this one in fact - seems my list missed timers and EEPROM among others. Perhaps the most useful one generically about interrupts is actually this one:
Pitfalls of using interrupts |

I often use VT100 terminal commands for uC interfaces. I will write a Tutorial if there is interest. The MMI is very simple, and processes a character at a time to navigate menues and change values or present information. VT100 commands for printing text at a specific location, clearing screen and changing test parameters will be demonstated. The MMI is written using Codvision, it should work with other C compilers.
I have also developed a VB6 application for a custom VT100-lite terminal. This could be a second tutorial.
Both of these will compliment the nice tutorial on USART rs232 by Dean. |

not strictly a topic i know, but id like to make a suggestion if i may
this forum is very biased towards C programming, would it not be possible to put assembly code snippets alongside the C code in these tutorial threads ?
i know its probably a big ask, but there does seem to be very little in the tutorial section for people (noobs like myself) starting to learn the assembly language |

| Try www.avrbeginners.net - a lot of the Asm "beginners" stuff already exists there so there's not much point in it being duplicated here. |

I think Tutorial on receiving $GPRMC and $GPGGA using ATMEGA controller would be helpful for all working on GPS based application.

| But that is just parsing a string which involves nothing specific to the AVR. |

| It would be great if you can make a tutorial about TWI/I2C, that is so mysterious, there's no single tutorial that explains it good enough to understand how it work just reading one tutorial, it's like a nightmare looking for some peaces of info all around the web. |

| I did a search for AVR32 related tutorials and couldn't find any. Of course I am no genius at searching so I may be wrong. Would there be anything wrong with someone posting AVR32 tutorials in this forum? |

Not a bad idea, especially given the xmega can do a multi-master configuration.
Bonus points for how to integrate with the SMBus of a standard PC for testing. |
