How do I set configuration bits in Mplab?
xx the configuration bits can be set by going to MPLAB IDE -> Configure -> Configuration bits. There is a check box that allows the user to specify if he wants the Config bits to be set in code (for this the writing specifications from the compiler user guide has to be followed) or to be set from the window.
What is Configuration bits?
Configuration Bits are a collection of binary data located in the Flash program memory of a PIC® microcontroller (MCU). Configuration bits are programmed into the PIC MCU with the application code. These bits are not executable code as their addresses are not accessible by the program counter.
How do I add header files to Mplab?
Do the follow:
- Click on the File-> Project Properties.
- Select the Conf -> C18 (Global Options) -> mcc18. For XC8, this is under Conf > XC8 compiler.
- Click on the “…” button of the propertie “Include directories”
- Click on “Browse Button”
- Locate you project directory.
- Click on Open, then Ok and Apply.
- Build your app !
How many instructions are available in 16F877A?
It has a smaller 35 instructions set. It can operate up to 20MHz frequency. The operating voltage is between 4.2 volts to 5.5 volts.
What is PIC32MX?
The PIC32MX family combines 32-bit performance with a large memory configuration and rich integrated peripheral set at a low cost to address embedded application spaces ranging from simple general-purpose embedded control to more advanced audio, connectivity and embedded graphics applications.
Where is hex file in Mplab?
When no configuration is specified, MPLAB X uses a default subdirectory called default. Within the dist\ directory, the HEX file will be found in the production subdirectory.
How do you set the oscillator to run at 4 MHz?
From the toolbar, select Debugger > Settings > Osc/Trace and set the oscillator frequency to 4 MHz.
What are different oscillator options?
Oscillators Types (LP, KT, HS, RC, EXTRC, EXTRC, INTRC, INTRC) The difference between modes KT, LP and HS is to select the different frequency range of internal oscillator.
How do you program a 16f877A microcontroller?
MPLABx Setup Steps

What are the types of instruction set used in PIC microcontroller?
Instruction Sets in PIC
- DATA TRANSFER GROUP.
- ARITHMETIC AND LOGIC OPERATIONS GROUP.

- Other instructions (Explained along with Program Flow Control)
What are configuration words in PIC32MX?
In PIC32MX family devices, the Configuration Words select various device Configurations. These Configuration Words are implemented as vo latile memory registers and are automatically loaded from the nonvolatile programmed Configuration data mapped in the last four Words (32-bit x 4 Words) of Boot Flash memory, DEVCFG0-DEVCFG3.
What is code protection on the PIC32MX?
The PIC32MX features a single device code protection bit CP that when programmed = 0, protects Boot Flash and Program Flash from being read or modified by an external programming device. When code protection is enabled, only the device ID word locations are available to be read by an external programmer.
