Help with assembly
I'm working with some inline assembly taken from an AVR library created by cpldcpu to control WS2912 LEDs. It's small and works great. However I'm trying to use a new type of LED...

Hesitant to switch from AS4 to AS6.1/.2
I've been using 4.18 for a few years now and it's been working fine. I do mostly 8-bit stuff with Tinys and Megas. But I'm thinking of upgrading to 6.1/6.2 since I want to getting...

Choosing a SEPIC converter
I'm building a SEPIC converter that needs to supply about 1.2A MAX at 9V from 6-14Vin. I've been doing a lot of searches and there are lots of converters that would seem to fit...

LCR meter 4070 modification
OK. So I rolled the dice on getting a cheap-o LCR meter. It's a model 4070 that can be found on eBay and other places. It's a neat little meter, but the ranges for inductance go...

Inductive load switching with FET
I have a PWM circuit that controls the RMS voltage to an incandescent bulb (actually 3 in parallel for testing) using PWM. I'm testing with the following parameters. Vin=38V, Vout...

SMPS/buck converter driven by AVR
I'm working on a RGB fading LED project. The LED has 3 dies in series for each color. So Vf would be in the range of 7-8V for red and 10-11V for Blue and Green. I want to drive...

FET "Turn on" speed
I'm looking for N-channel FETs for a PWM based regulator. To reduce heat dissipated during switching events I want to use an FET that can be turned on and off as fast as possible...

LC filters on Vcc and ADC input?
I've read the docs on several of the Atmel chips. The ones with an AVCC pin show a 10uH coil and a 100nF cap. I understand this is to clean up the analog input for use with the...

codevision doesn't see AVRISP MkII
I've just installed CodevisionAVR Eval ( 2.04.8 ). I have an AVRISP MkII (with latest firmware) that works just fine with AVR Studio 4.18. But WinAVR-20100110 doesn't contain...
