i need to know if there is library for functions to write and read by I2C OR SPI in mplab with high_tech universal suite compilor.....THANKS
 

I also want to know if there is a already function on hi-tech, even I have use SPI and I2C with own function.
 

Yes and No.

There are not library functions available in the Hi-Tech C for PIC10/12/16, like there are in other Hi-Tech C Compilers for other PIC families. However, there are sample programs with contain ready made function for I2C . These sample programs and the source and header files for the respective protocols can be found within the sample directory:

C:\Program Files\HI-TECH Software\PICC\9.81\samples
Click to expand...




Also, a nice collection of example programs and functions for SPI and other interfaces are available at:

MicrochipC - C sample code for PIC micros and Hi-Tech C

You can adapt some libraries from the PICC18 to PICC compiler with a little work as well.

Hope the info helps in your endeavors.
