=== Setup PICC + PIC16F72 ===
==== Build Guide MPlab IDE ====
[[File:PIC-toolchain.gif|thumbnail|toolchain setup animation]]
* Updated with animation tutorial
* Install MPLAB, HI-TECH PICC9.83
* select MCU -> pic16f72
* programmer -> pickit3
* project wizard -> use compiler hi-tech universal toolsuite -> ANSIS
* click to compile the default project, blink RA0 LED
==== build first demo and flash ====
[[File:Flash pic.gif|thumbnail|Upload code]]
* Must select proper configuration bit, check crystal, LP - low power, RC internal, XT external, HS high speed crystal, for 8M crystal should use this one, read more on datasheet
* Demo use pickit standalone programmer, configuration bit set to 3FF2
* Crystal - HS crystal
* WDT - disable -> 0
* Power-on timer - enable -> 0
* BOR - enable -> 1
* LP - code protection off -> 1

image:New_project_05.jpg | no need to add any files for now our blink project
image:New_project_06.jpg | add a file to project
image:Main.jpg | call it main.c
image:Main_02.jpg | first buid it 1, then program it 2, add LED to see how it works
image:Pic16f72_blink_led.jpg | final blink led
