What is the difference between pic16f87x and pic16f877/874?
The PIC16F87X devices have a 13-bit program counter capable of addressing an 8K x 14 program memory space. The PIC16F877/876 devices have 8K x 14 words of FLASH program memory, and the PIC16F873/874 devices have 4K x 14. Accessing a location above the physically implemented address will cause a wraparound.

Overview
A bootloader is used to quickly download a new program into your PIC micro, in a few seconds. Update 2016-03-09. Code is now on GitHub. Once you have it set up, you can quickly update the .hex file in your PIC micro with a single keystroke. NOTE: You cannot use this bootloader without first programming the "bootstrap" hex file into the PIC using a
Hardware
To use the bootloader, you will need an adapter, which plugs between the COM port of your computer and the PIC microprocessor. A serial adapter converts the RS232 to TTL levels, -13V to +5V and +13V to 0V. The PIC reads these TTL levels into its hardware serial port. Feel free to make an adapter up yourself. Circuits for PIC >> RS232 comms are expl

Compatibility List
Check if your compiler / assembler is compatible. If you find that the bootloader works on a compiler/assembler not listed in the list, please email support@microchipc.comso I can update the list. Thanks See full list on microchipc.com
How to Port The Bootloader to A Different Microcontroller
I can't do the work for you, but here are some hints to get you started: Step 1: Get the UART working on the 16F628 i.e. Get it talking via RS232 serial. In the source code, see the directory "hex files for testing serial comms on PIC". Open the C source, compile it, get it working. Step 2: Work out the difference in memory size between the 16F628
Picboot Plus
An alternate bootloader interface which includes a terminal is available in the latest distribution download. The screenshot is shown to the right. From readme: PIC Bootloader + Terminal, September 2004 Most PIC applications that I develop include serial link to commuciate to some terminal-console program so I thought it would be handy to integrate

The picture below shows how to set up the bootloader on a breadboard. The big white DIN plug on the top right plugs into the PAS12 serial adapter, which goes into the serial port of your PC. The white button with the arrow on it is for resetting the PIC. The other components are a 5V regulator, and a 800mA polyswitch to switch off the current in ca

From Argentina: Hi and first of all THANK YOU VERY MUCH I'm already using your bootloader. In 2 hours (soldering serial cable included) I got it running over a 873A. Just at second attempt it works
