reikia pagalbos, man reikia uzprogramuot atme16 arba at89c51 (jokio skirtumo, gali but panasus i sius), tas mikrokontroleris jungiasi su mobiliaku.
Gal kas turit pavyzdziu skirtu tokiems kontroleriams(panasiems).
butu dar geriau jei pvz butu mikrovaldiklis kazka darytu su telefono (mobiliu)
jei tokio pvz neturit, tai siuskit bet kokius programu pavyzdzius skirtus atme16 arba at89c51 (ir panasiems) kontroleriams.
Labai jums aciu

Na bet matosi kad žmogus neturi net žalio supratimo ko prašo. O tuo labiau aš neįsivaizduoju ko jis nori...
O kas per valdiklis atme16  Naują rūšį išgimdei? |

na skubujau rasyt tai ATSIPRASAU, taip valdiklis ATMEGA16
Man reikia pavysdziu programu.
programos parasytos su C kalba.
mikrokontroleriams ATMEGA16 ir panasiems.
pavyzdziu tema: kai mikrokontroleris sujunktas su mobiliaku ir kanors daro,
nusiunti SMS i mobilika o kontroleris kanors ijungia.
TOkio aisku niekas neturesit.
arba kai prijuktas DS18s20 arba DS1821 (termometrai)
arba LM555 (itampos keitiklis i dazni)
geriau kad PVZ butu paprasti, tam kad galeciau paziuret kokios komandos naudojamas ir aplamai kaip vyksta programavimas kontroleriu su C kalba.
stai tokiam dalykui reikia.

| Gal tu eik geriau tutorialą skaityt ir nesiteisink, kad skubėjai, bo dviejose vietose identiškos klaidos. Čia jau ne skubėjimas... |

Ech.. toks vaizdas kad tik ziurima kas ilgesni koda papastins... Moderas budamas ispejimus gautu tokie.. jei jau ilgas kodas tam yra visokie pastebin...
o zmogui del mobiliako manau apie UART reik kodo visgi tie telefai kiek zinau taip ir bendrauja (TX,RX).. |

taigi yra tas kodas... UART. Va:
//******************************************************************************
void USART_Transmit( unsigned char data )
{
/* Wait for empty transmit buffer */
while ( !( UCSRA & (1<<UDRE)) )
;
/* Put data into buffer, sends the data */
UDR = data;
}
//******************************************************************************
Parasai programoje :USART_Transmit( data ) ir siuncia...
Kai kas isivaizduoja, kad uztenka parasyti keleta eiluciu ir duomenis yra siunciami... kad parasyti net nedidele programele kontroleriui butina suprasti jo veikimo principus, struktura ir moketi ja sukonfiguruoti ir suvaldyti... |

| jei tu resusrsu einamu momentu niekam nereikia, tai ar gaila tu resursu? Viskas cia OK. |
