I needed a frequency reference for tuning up the RS-232 to 100 MHz RF desktop channel adapter elsewhere on this site, when I found this Saronix crystal oscillator in my junk box. A few minutes with AVRStudio produced an ATtiny12 to make a tone – even fewer parts than using an NE-555. With the addition

Just the solution for AVR applications in which I/O is tight, such as the ATtiny12. This should work well on other kids of controllers that have independently controlled I/O direction registers, such as PIC and 6805 controllers. This is a solution was devised for those I/O limited 8 pin controllers like the AT90S2323 (though I

Download the test program with driver: i2cm030710F.asmI had been putting off writing a driver for some 24LC64 and 24LC256 EEPROMS I was thinking about using, when I came across a temperature logger application written by Sean Ellis. The Temperature logger was posted on on www.avrfreaks.net on January 10, 2002, project ID 49. The original application

This technique uses digital I/O pins to multiplex analog voltages into an analog input on the microcontroller. The method is most suitable for signals that do not need to be sampled frequently and it may be extended to accommodate a large number of inputs, though for a large number of inputs, the use of a

Described are the waveform capture method, example firmware and hardware designs. This material formed the basis of an article that was first published in the October, 2003 issue of Circuit Cellar magazine. The only components added to the operating Atmel AT90S2313 circuit (one capacitor and two resistors) to allow waveform sampling with < 1 microsecond resolution
