Source Code - C
A program written in the high level language called “C” which will be converted
into PICmicro machine code by a compiler. Machine code is suitable for use
by a PICmicro MCU or Microchip development system product like MPLAB
IDE.
Source File - Assembly
The ASCII text file of PICmicro instructions and MPASM directives and
macros (source code) that will be translated into machine code by an
assembler. It is an ASCII file that can be created using any ASCII text editor.
Source File - C
The ASCII text file containing C source code that will be translated into
machine code by a compiler. It is an ASCII file that can be created using any
ASCII text editor.
Special Function Registers
Registers that control I/O processor functions, I/O status, timers, or other
modes or peripherals.
Stack - Hardware
An area in PICmicro MCU memory where function arguments, return values,
local variables and return addresses are stored, (i.e., a “Push-Down” list of
calling routines). Each time a PICmicro MCU executes a CALL or responds to
an interrupt, the software pushes the return address to the stack. A return
command pops the address from the stack and puts it in the program counter.
The PIC18CXXX family also has a hardware stack to store register values for
“fast” interrupts.
Stack - Software
The compiler uses a software stack for storing local variables and for passing
arguments to and returning values from functions.
Static RAM or SRAM
Static Random Access Memory. Program memory you can Read/Write on the
target board that does not need refreshing frequently.
Status Bar
The Status Bar is located on the bottom of the MPLAB IDE window and
indicates such current information as cursor position, development mode and
device, and active tool bar.
Step Into
This command is the same as Single Step. Step Into (as opposed to Step
Over) follows a CALL instruction into a subroutine.
