pic16f877a tutorial

hi,
i am currently doing a project using pic16f877A, i will be using 2 infrared sensors to detect obstacles. can any one give any tutorials or sample C++ code for PIC16F877A? and my infra output is analog. Its ok if the code is not for infared. any code written in c++ for pic16f877A is ok.



cheers,
Chang

pic16f877a tutorial on c

To my knowledge, there's no C++ compiler for PICs, because PICs are just too small to suppot C++. There's a number of plain C compilers, though.

how about try going to the vendor microchip... i believe that there exist such one... you will program pic in c language and the compiler will translate it to assembly... i have used such during undergrad class.

what does nop do on pic16f877a

hi ya,
this is good.. can i ask about the code. how u define this? can u explain?
PORTD = 0b11111111;
TRISD = 0b00000000; //=1 laf IN, =0 la OUT
PORTD = 0b00000000;
TRISA = 0x255;
TRISB = 0x255;
TRISC = 0x255;

and do u have any idea if i want to write a code using infrared sensor to control the motor?

Hello,
You should download MPLAB from the microchip.com web site and then the PICC Lite compiler from the hitech.com and the user guide and it comes with some explained examples

Regards.

TRIS is used to define a port is input or ouput , use can define a bit in portD [D7.......D0] exam you can define TRISD=0b10101110 , this mean D7 is input, D0 is output .......... 0 means output , 1 means input
TRISA=0x255 is other way to define direction of port , it is the same TRISA=0b11111111
PORTD=0b0000000 mean we assign the value for PORTD

there is C++ compiler for PIC microcontrllers.
visit www.picant.com

sorry,
could i ask that how do u get the pic.h header file from, cause i don`t have any ideas about the variables set in the header file. I will like a copy of the header file if possible to write some code. I need to know the commands like PORTA = the address in pic16F877A, so we could use directly in programming in c.

pls help
