avr - why is the clock of my atmega16 not working correctly, has anything to be configured? -


i haven't connected oscillator circuit in atmega16. doesn't have work on it's default clocks? please answer me, if other configurations required or settings have done in dumper program itself? using code vision avr , generates codes itself, tried avrstudio code, didn't work! beginner trying make digital clock on 16x2 lcd, lcd stuff okay! timer has problem, it's not showing correct resolution!

  1. hw issues, ensure have @ least 100nf folium capacitor between power , gnd on atmega16. have it? should have larger electrolytic filtering capacitor 100uf whole project. have high enough voltage run clock frequncy? check datasheet required voltage.

  2. read fuses determine if have internal oscilator configured , determine internal clock frequency should have, review code if makes more sense. there link checking fuses directly code vision
