Trick GCC into thinking I have 32K or RAM on XMega256
I am attempting to shoe-horn some (manufacturer)supplied code into an XMega256, but currently, the build process dies because I've reached 129% of RAM space. I can almost...

Two "solutions" open at once?
It would be useful to me to have two AS6.1 solutions open at the same time for various cut-and-paste and comparison purposes. Is there a way to do this? I can, if push comes to...

MEMS Gyro > 200d/s
All the MEMS gyros I can find at sensible prices seem to top out at +/- 2000 degrees/second, which may not be quite enough for my application. Strange, as I'd have thought the...

Small buck/boost
I'm looking to get 4V at 30mA output from a single LiPo cell, say 3V up to 4V2. I tried the TI simple switcher site, but it was giving me crazy 2A output circuits. Anyone have any...

Zigbee versus BT 4.0 (LE)
Looking at a possible "cable replacement" project, and from a quick look round the web, it would seem that BT 4.0 is cheaper han Zigbee, even though Zigbee is designed to be...

What resistor values to allow TPI programming in circuit?
I have just searched the ATTiny4/5/9/10 datasheet, AVR918 and AVR042 in vain to try to get a feel for what value of resistor I should use to allow the reliable use of the TPI on a...

Reset conundrum
I have a product, and I would like to have a way for the user to do a hard reset as a last resort. The device is permanently powered, and spends most of its life in power down...

ATTiny44A reading bandgap with Vcc as ref
When reading the 1V1 bandgap using Vcc as vref, I find that I need to add a fairly long delay after setting the MUX register for internal 1V1 bandgap. I have come across this...
