[TUT][HARD]Differential ADC For Monitoring Voltage Window
There is a voltage divider on the input of the ADC to increase the measuring range from 2.56V to 14.4V. To ensure a min measuring range of 14.4V you have to consider the resistor...

RTC terribly inaccurate, help?
Quote: ldi temp, $b7 out OCR1AH, temp ldi temp, $1b out OCR1AL, temp AVR timers always starts counting from 0 not 1. Thus setting OCR1A to 46875 (0xB71B) will trigger...

Little help (in using timer to flash LED)
Timer1 of the ATtiny861 is different to the timers in other AVRs. In normal mode OCR1C defines the TOP value of the counter. You haven't initialized OCR1C thus it still holds the...
