avr prototyping boards
Another "Freeduino" board: That's more geared to breadboard hookups, no solder proto area, but it looks very nice if what you're really after is...

SD-Card, 4bit parallel mode
For several years now there's been a public version of the SD spec. The main thing it omits is how to access the "secure" part of the card ... although ISTR there are also some...

Dual row 0.1" header pins
The breakaway headers are nice because you can use them with breakaway male headers for board-to-board connectors. Re "never seen them" ... I don't have an STK500, but the...

Dual row 0.1" header pins
What Fry's utterly lacks is breakaway FEMALE headers ... Last few times I searched for them, I couldn't find those at DigiKey either. Anyone got part numbers?

Quote:SPI is an eight bit shit register Erm, that's AVR8-specific. More generally, SPI is specified in terms of bits. If a master or slave wants to group those into words of...

STK1000 Power supply
J16 on the NGW gives raw access to the NGW power supply input voltage. Stick a 5V regulator on that as part of your LCD card.

The TC function in UC3 is just not as good as it was in AVR
The TC in the UC3 (and ap7) is the same one that has been used in the AT91 series, unchanged for many years now. I never much liked it there either. Perhaps Atmel will finally...

Linux I2C driver broken?
Plus a second patch (!) at

High resolution timers solutions for kernel?
I'm sure I've seen patches making the TC module support standard Linux kernel high res timers from ... two counters chained to create a clocksource, the other used for a oneshot...

/dev SPI....[Finally resolved...]
you might need to mknod the devices by hand ... "mdev -s " ought to make them for you, but it doesn't seem to understand some things about sysfs.

Serial EEPROM, reccomendations?
Decide on how you connect first, then the rest follows. Most I2C eeproms talk the same protocol as Atmel's AT24 series. Most SPI ones talk the same protocol as their AT25 series...

Why the TWI bus is only fixed at PA9/10 on UC3B?
You have a couple options for implementing i2c. One uses the TWI controller ... which seems kind of glitchey and wierd, so if you're doing a host side implementation you might...
