Sim900 + Pic 16f877a sms controller

[MariusTehnik]

Buna seara , am un proiect facut cu un modem gsm sim 900 si pic 16f877a . Am 3 gsm shield-uri din care doar unul functioneaza corespunzator , comunica cu placa si raspunde la toate comenzile, problema e cu celelate doua module care desi testate , nu functioneaza impreuna cu pic-ul

Modulele le-am testat in hyperterminal si raspunde la toate comenzile AT date ( de pc)

Poate ma lamureste cineva care ar putea fii problema cu cele 2 modemuri 

Folosesc 2 max-uri max232ecpe si pic16f877a si modemul din imaginea din link-ul de mai jos

De ce-ti trebuie max232?

[MariusTehnik]

Initial foloseam un telefon sony ericsson t290 si am trecut pe modemul gsm , asa a ramas montajul 

Nelamurirea mea e de ce un modem merge si 2 nu , am sa testez si varianta fara max-uri ....conectat direct la pinii rx / tx al pic-ului

Folosesc pinii D7 si D8 al modemului , software serial

Nu stiu cum functioneaza modemurile alea, numai ca sunt sanse ca MAX sa strice.

Daca chiar face nivelurile RS232 (+/-12V)...

[MariusTehnik]

Am sa testez fara max-uri sa vad ce rezultate voi avea , revin cu rezultate.

[MariusTehnik]

rezultatul e negativ ,  refuza sa functioneze :( doar un singur modem functioneaza cu max-urile aferente

[MariusTehnik]

In seara asta am testat modemurile cu problema conectate la calculator printr-un usb-ttl si in simulare functioneaza , nu am idee ce sa mai fac .. modemurile par sa fie ok din punctul asta de vedere

softserial#serial si apar probleme inexplicabile de comunicare si daca adaugi o linie de cod care nu face nimic.

am patit asta si folosesc numai serialul hardware, fac debug pe un display de nokia conectat temporar, pana pun totul la punct.

 

nivelele pe rx,tx netranslatate corect.

Fara sa arati codul folosit nu cred ca te poate ajuta cineva.

[MariusTehnik]

Am sa incerc sa atasez codul pe forum

Cu intarziere dar am avut alte probleme de rezolvat si proiectul sa amanat.

In codul postat de tine nu se vede cat este baud rate pentru USART atunci cand faci initializarea.Functia de initializare arata asa: void Usart_Init(const unsigned long baud_rate);Probabil la SIM900 baud rate default este 19200 bps, probabil ca stii si cat este la fiecare modul testat.Eu stiu ca baud in PIC si in SIM900 trebuie sa fie la fel.

[MariusTehnik]

La sim900 baudrate-ul e setat pe 9600

Acum am vazut ca eu am dat functia din mikroC.La tine ar trebui sa ai setarile in usart.h, dar nici pe acesta nu-l vad inclus in cod.Trebuie sa ai 9600 si pentru USART.
