Hjælp i grænseflade ATmega32 med GSM-modem

Hej der ..

Jeg brugte dette program bruger codevision AVR.Det prøver med og AT CMGF = 1 kommando ..

Code:

Nogen svar venligst ..

Du skal muligvis slutte RTS signal af GSM-modem.Hvis du bruger SIM300, som kan være et problem.Du er også nødt til at tilføje

mens (1);

for noget lignende i slutningen af Deres vigtigste funktion
