Programare ATmega128

Recommended Posts

Guest DragosVok

Am si eu urmatoarea rugaminte: trebuie sa programez un microcontroler ATmega128 astfel incat sa memoreze temperatura(de la un senzor lm335) din minut in minut timp de 24 de ore si sa comunice printr-o interfata seriala la PC. Nu ma pricep la programare, asa ca ma poate ajuta cineva cu un program (preferabil in c) sau cu niste sfaturi.PS. de la PC trebuie date 2 comenzi: 'r' - read, 'd' - delete.Multumesc

De ce folosesti ATmega128? era mai bine un ATmega162, are si RTC, un program gata facut eventual ptr. bani, sfaturi pe gratis :),corectez: ATmega162 nu are ADC, dar un ATmega16 cred ca ar fii deajuns...

daca folosesti "Differential Programmable Gain" poti avea o precizie mai buna a temperaturii citite.Direct,folosind doar conversia analog-digitala, mi se pare ca poti citi cu o precizie de doar o jumatate de grad.

Cel mai bun site despre avr-uri ce am vazut eu pana acum este: avrfreaks.net, acolo gasesti proiecte open source, tutoriale, proiecte complete etc...
