Problema cu nokia 3310 lcd

[lama]

Salut

Nu stiu shield tau dar eu am folosit niste pcb cu 3310 montat pe ele.

Ce am constatat diferit la mine fata de tine sunt niste timpi in initializare

Plus eu am avut mari probleme cu contastul. A trebuie sa ma joc succesiv pana a aparut ceva pe ecran

La mine initializarea arata c-am asa

void init_nokia(void){	// nokia LCD init		nok_dc=1;				// bytes are stored in the display data ram, address counter, incremented automatically		nok_cs=1;				// chip disabled		__delay_ms(10);								nok_res=0;				// reset chip during 250ms		__delay_ms(250);		nok_res=1;							bytefornokia=0x21;		// set extins extended instruction set		nokia_write_command();				bytefornokia=0xc5;		// Vop  was 0xc5 // better is 0xa0		nokia_write_command();				bytefornokia=0x13;		// bias 		nokia_write_command();				bytefornokia=0x20;		// horizontal mode from left to right, X axe are incremented automatically , 0x22 for vertical addressing ,back on normal instruction set too 0x20 for horizontal		nokia_write_command();				bytefornokia=0x09;		// all on		nokia_write_command();				__delay_ms(250);		__delay_ms(250);							 		nokia_build_DDRAM();	// reset DDRAM, otherwise the lcd is blurred with random pixels				__delay_ms(10);				bytefornokia=0x08;		// mod control blank change (all off)		nokia_write_command();		__delay_ms(10);						bytefornokia=0x0c;		// mod control normal change 		nokia_write_command();				nokia_gotoxy(0,0);}

De curiozitate in montaj ai si tu un led ca sa vezi ca il poti licuri/blinkai?Eu fiind incepator tot timpul pun un led, tocmai pentru verifica ca imi merge.
