Thanks for getting back to us!  Far too many times these things just disappear into oblivion.  S.

Modifying project configuration with command line
I'm actually considering something similar - Using a python script to automate AVR programming, but to do so while reaching into the .hex output file from the compiler,...

Does frequent reading slows down DS3231 RTC???

Does frequent reading slows down DS3231 RTC???
It is true that rapidly reading an RTC should not cause timing errors.  Should not.  They should also latch all the time registers simultaneously at the very start of...

Atmega328P Morse Code /w 4 digits
To be perfectly fair (and go back to the 'helping!' thing) I came up with just about the same thing as Simonetta, although I used $01 as a dot, $02 as a dash, and $00 as a...

Atmega328P Morse Code /w 4 digits
Some years ago I built an AVR-based gadget (designed for a 90S1200, and written in assembler) that flashed my Christmas lights in Morse Code.  It had [A-Z, 0-9] but no...

RTC Chip Recommendation?
Intersil ISL12022 Microchip MCP7940   I'm actually using the MCP, but the ISL does automatic daylight savings time (if you care).  You can set when DST goes in and out...

How to use two 8bit ports to form a 16bit port ?
Minor problem with that is that although they may have sky-high clock speeds, they are also heavily pipelined, cached, &c., and a pipeline flush or a cache miss is a massive...

Program avr microcontroller to have 3V on one output pin
In theory, you could use PWM and a low-pass filter, but I'm with JS on this - Just use as Vcc the voltage you need on the pin.  Or get an Xmega what has a DAC built in....
