I start my first programming >>> PIC 12C508A.
Must i write the I2C by software means? when yes as?
I search courses in beginners who can recommend you to me.
For your aid I am in advance very much thankful.

most of the midrange PIC uC have i2c hardware built in, look for a module called SSP or MSSP (synchronus serial port). However, I don't think that module exists in the 12 series, they're just too tiny ... so you will need to emulate the different timings and whatnot, with software.
I don't have any examples for you, but I'm sure there are some at microchip.com and certainly google.com
the 508 as I recall, is an 8 pin device, with 5 I/O and 1 Input-Only pin ... I'm not sure I'd "waste" 2 of my I/O lines with an i2c eeprom ...some of the newer 12F chips have eeprom built in, or perhaps consider 1-wire eeprom?
Yes, you need to write it in software, you might check my tutorials which give I2C software, but for the 16 series PIC's - I'm not sure if the routines use any of the instructions the low-end 12 series don't have?.
However, the 12C508 is a really old device, and OTP (One Time Programmable), far better to use a modern FLASH/EEPROM device so you can reprogram it (without buying expensive JW UV eraseable versions). There are a number of modern 8 pin PIC's, including a FLASH version of the 12C508, the 12F508.
