TRISC = %00000000 serout portc.6 , T2400 , ["HELLO "] ;) Title: Re: cant communicate pc to pic Post by: Ikaros on August 31, 2007, 10:27:36 10:27 The program just wait one character and then ends. May be is better to make a loop to continually read the Serial Input?
Also are you sure about your hardware connections? Title: Re: cant communicate pc to pic Post by: Ret12_12 on August 31, 2007, 07:43:59 19:43 If you try case 1 instead of "1" also proton you said DEC serindata .....
You can have RS232 com. without have the MAX232 SerOut PORTB.0 , 16780 , ["1-PORTA.0 Yuksek Yap ",13,10] ' transmite to 2400 with a serious res 1k to pin 2 in pc side (9 pin) Title: Re: cant communicate pc to pic Post by: mcr on August 31, 2007, 09:34:22 21:34 this serin doesnt work.I use max232 and get the characters on hyperterminal but cant on led. please help.

Title: Re: cant communicate pc to pic Post by: mcr on September 01, 2007, 05:08:06 17:08 Use Serout2/Serin2 and direct connection to pic ( not with MAX232) Forgot about that :-[ But still, If you use a MAX232 the information should be displayed, does not matter if it's correct or not.

I change T2400 con 0 with include "modedefs.bas" serin portb.1,T2400,[serindata] with serin portb.1,T2400,serindata I use 16f84,max232 pic pin7 - max232 pin 9 - max232 pin8 - dbp pin 3 pic pin6 - max232 pin 10 - max232 pin7 - db9 pin 2 pic pin17-led I coludnt high or low led on hyperterminal.I get characters on pc side however.So I used a program named terminal. Then its ok. |
