programare Cerebot ATmega64

[Dark_Soul]

Salutare. La Multi Ani.Am doi foto tranzistori fiecare in fata la cate un led galben care e tot timpu aprins. Cele 2 iesiri (colector) al fototranzistorilor(in functie de starea fototranzistorului deschis sau inchis) trebuie sa le leg la cate un port de intrare in Cerebot. Problema e ca nu stiu sa construiesc programul in AVR, nu am nici o idee cum ar trebui inceput.Programul trebuie sa contorizeze starile de H sau L pe cele 2 porturi, si sa afiseze pe ecran de cate ori sa intrerupt primul fototranzistor, si de cate ori cel de al doilea.Daca cineva de pe forum a facut acest proiect, sau are idee de ce si cum, il rog frumos sa ma ajute. Nu raman dator

Daca postezi o schema te ajut cu mare placere !In Bascom programul ....

nu cred ca mai folosesc LCD, mai bine folosesc afisajul cu segmente cu 8 pini

nu stiu daca e bun codul pe care il am...

[danzup]

Codul care l-ai postat e pentru LCD .Pentru afisaj cu LED cu 7 segmente trebuie rescris partea de afisare , si ti-as recomanda 2 decodoare BCD/7 segmente pentru ca overheadul afisarii s-ar putea sa-ti lase putin timp microcontroler pentru altceva la robot care trebuie sa reactioneze totusi in timp real .Cunosc programare in C dar nu te pot ajuta pentru ca nu sunt un profesionist in C.Dupa cum am zis in Bascom pot sa te ajut .

[Dark_Soul]

nu stiu ce e Bascom..

[danzup]

BasicCompilator pentru Atmel AVR

http://www.mcselec.com/

si este un download free la ultima versiune de bascom

[Dark_Soul]

pai cred ca e ok daca scoate hex si il pot pune pe CEREBOT, nu?

[danzup]

pai cred ca e ok daca scoate hex si il pot pune pe CEREBOT, nu?

Da.Dar nu pune baza mare in mine , ca stau extrem de prost cu timpul !Printre picaturi te ajut....

[danzup]

interfatare atmega / 7 segmente

[Dark_Soul]

Atmega64 e cipul, da placa de dezvoltare e CEREBOT...

[danzup]

Pai si care e problema ?Ai scoase la conectoare pinii lui atmega64 !

[Dark_Soul]

da , mai trebe sa retusez codul... nu ai ceva cod similar in bascom?

[danzup]

Ba da! Am sa-ti dau codul in Bascom pe care l-am scris pentru o aplicatie cu 2 digiti LED 7 segmente.Cand ajung deseara acasa . O sa postez aici ....mai bine inveti Bascom pentru ca poti face absolut totul ce faci si cu Asm si cu C .Cum spuneam : nu conteaza pe unde mergi important e sa ajungi ok la capatul drumului in acelasi timp cu ceilalti .

[Dark_Soul]

bun, da ce limbaj e BASCOM? un fel de.... C?
