mplab IDE v8

[16F877A]

hi , i have a project that have to use 16f877A as the main of the whole project , and have to use mplab Ide v8 to write the instruction , but i dunno how to start up . i need some easy example to understand the coding . and what project that i can do wit the PIC .

There are plenty of examples in my tutorials.

ya i saw alot of example , but the examples using 16f628. its same wit 16F877A ??

in the tutorial , i really dun understand wit the configration setting , as i saw some example for 16F877A is - _config_cp_off&_0ff&_xt_osc&_pwrte_on. different PIC wit different Config ???? i veru confuse , as i still dun understand the code . thanks^^

The 16F628 and 16F877 use the same 14 bit core, and my tutorials list the minor changes required.

Config fuses set the basic options, oscillator type etc. - my tutorials, as they were written for specific exact devices give the simple hexadecimal version of the value. The example you give above is instructions to the compiler, which then generates the value during assembly - as you're changing the device, it's best to use the method you showed.
