Of course I haven't.
The program I wrote in Master device was shown below:
#include <16F876.h>
#fuses XT,NOWDT,NOPROTECT,NOPUT,NOBROWNOUT,NOLVP,NODEBUG
#use delay(clock=4000000)
#de ...

Except the SPI issue.
My I2C worked, but not well enough. As the program for master device were shown below:
#include <16F876.h>
#Fuses XT,NOWDT,NOPROTECT,NOPUT,NOBROWNOUT,NOLVP,NODEBUG
#USE ...

I have quoted, but it still did not work, could you please check if my connection was ok.
Or this interface can not be simulated in ISIS at all !?

Dear all,
I have changed codes but it still not worked, for my circuit, I just connected master device SCL PIN_C3 and SDO PIN_C5 to slave device SCL PIN_C3 and SDI PIN_C4. I have not put pull_up resi ...

Thank you very much indeed.
The program compiling was fine but when I simulated it in ISIS, the LCD screen would still display:
SPI data:

Dear all,
I am trying to compile data transfering with mode of SPI, for my master device, the code was shown below:

My project was to use PIC16F876 to drive a 16x2 LCD module. SPI and I2C were two interfaces needed to build in it.
As treating my LCD module as a slave item, I wanna simulate my design in ISIS, my RS ...

please tell me the right place I can post about my question.
and that's the last question, if you know the answer please give me your suggestion, I will stop post it.
thanks.

As a frashman using this system, I am not really familar with your rules.
Sorry to bring you so many troubles.

Dear all,
after building RS232 interface in my LCD module, I wanna build I2C and SPI interfaces into it as well, is there any friend who can give me the suggestion about the code for those two inter ...

dear sir,
after RS232 interface, I also need build I2C and SPI interfaces into my LCD module, after reading the datasheet of PIC16F876A and the help file of CCS Compiler, I have been sure about the w ...

thanks millian about your help.
it works.
By the way, if I wanna input number of x which was large than 10, how can I do that?

My codes were rectified as follows:
lcd_putc("\f Input x: \n");
x=atoi(getch());
lcd_putc(x);
delay_ms(500);
lcd_putc("\f Input y ...

Dear all, I communicate my LCD module with my PC in RS232. When I type two number such as x=8, y=0 to run the rutine of lcd_gotoxy(Byte x, Byte y) the cursor would not point to the exact posit ...
