Problem with brown out
I have enabled the brown-out option, but still he refuses to stand down. What's going on?

Can I stop GCC using a certain area of code space?
Because of a minor cockup(by me) with a bootloader, I have ended up unable to bootload anything into the 0xfc00 - 0xffff region of a Mega1281. You can probably guess how this...

Over-aggressive inlining violated my TWI bus timing...
and now I feel dirty. Or so I believe, I haven't managed to quite get to the bottom of this yet, but using the latest version of WinAVR (I have been using 20060125 since, well,...

WinAVR with AVR Studio
I don't know whether this rightly fits in this forum or the AVR Studio one, but it's such a dumb question that it probably doesn't matter anyway... I have been using WinAVR for...

Mirroring a VGA signal.
An old client of mine has an application where he wants to mirror a VGA(SVGA?) display, so that it can be viewed in a mirror. Apparently, a lot of smaller LCD screens have a...

Union of structures?
This is more a general C question than GCC specific. I have a 32 byte block of data that will eventually be written to a TWI EEPROM for logging purposes. However, depending on the...

Does wdt_enable(x) preserve the state of the WDIE bit?
Errr... I'm not sure how to add anything to the subject - I want to use the watchdog interrupt facility on a Mega1281, but I'm not entirely sure if, when I change the watchdog...

RF noise generator ideas.
I'd like to build a noise generator, to produce white(ish) noise in the 50 - 100MHz spectrum, 75 Ohm output. It's for Cable TV testing purposes, nothing sinister. I'm hoping that...

Problem with 1281 bootloader/missing main address.
I've been having strange problems with my bootloader on a Mega1281 design. The circuit and the bootloader are virtually identical to a Mega64 design that works flawlessly. The...

Which is best?
I think we should nail this once and for all.

Max speed of TWI
In the Meagre64 datasheet, the following note is found: Quote:Bit Rate Generator Unit This unit controls the period of SCL when operating in a Master mode. The SCL period is...

Changing TWI speed "on the fly"
I'm having to add a 100K I2C(TWI) part to an existing design in which all the other I2C parts run at 200K. Since the application spends a lot of time performing I2C transfers, I'm...
