Post by thread:[PIC]: PIC16F628

Hi list! would you tell me what is wrong with the following code please ! *************************************************** #include <16F628.h> #include <stdio.h> #fuses INTRC,NOWDT,PUT,NOPROTECT,NOBROWNOUT,NOLVP,NOMCLR #use fast_io(A) #use fast_io(B) //#use fast_io(C) #use delay(CLOCK=4000000) #use rs232(baud=9600,xmit=PIN_A7,rcv=PIN_A6) void Ini(void); void main() { Ini(); while(1) { printf("\nTest "); } } void Ini(void) { port_b_pullups(TRUE); setup_timer_1(T1_DISABLED); setup_timer_2(T2_DISABLED,0,1); setup_vref(FALSE); setup_comparator(FALSE); set_tris_a(0x00); //All OutPut set_tris_b(0x00); //All OutPut } ************************************************ I am just trying to use RA7,RA6 instead of RB1,RB2 for the serial communication . any comments,ideas please?

Try standard_io mode for port A. I have never found a real need for fast_io mode. Just a guess, but commenting out that one line may well solve your problem. Dale --- We are Dyslexia of Borg.

Hi Salah, Sorry but I do not under stand "C" too well, but if you are using the in built SCI (Serial Communications Interface) you can not change the pins out as this is a hardware device. Yes it would be nice to use the ISP connector for serial port but it is not going to be easy... The only way to use pins RA6 & 7 would be to write a bit banging routine, this will require a lot more programming, use a lot more memory, probably need to use interrupt routines and a timer, lot easier to use RB1 & 2.

Hi Salah: Maybe you could set your fuses configuration to INTRC_IO . Your are using INTRC config wich doesn't release the RA6 and RA7 for I/O ... Maybe that's your problem. I used many times the serial routines of the CCS compiler in many diferent pins and it always worked ok. As stated in the CCS compiler manual , the SCI will be used only if you assign the SCI pins.
