Tiny PIC bootloader using PIC16F microcontroller

Tiny Bootloader

This is a bootloader for the Microchip PIC microcontrollers.

• It is the smallest bootloader, taking less than 100 words of program space;
• Supports families of PIC devices: 16F, 18F, dsPIC30 (those devices that support self-programming)
• Does not support yet PIC24, dsPIC33, PIC18xxJyy

Features of the firmware

• Size of only 100 words; (all versions, for 16F,18F,dsPIC occupy less than 100 words);
• Can write flash, eeprom and configuration bytes(18F);
• On reset, waits 1 second (adjustable) for a message from the PC, if not received, launch user application;
• The .asm file can be easily modified and adapted for any frequency (or baudrate);

Features of the PC software

• Can upload programs into flash (in current version eeprom and cfg bytes can be modified only manually, depending on the device type);
• Works with PIC16F,PIC18F and dsPIC types; automatically detects HEX content and PIC model;
• Remembers last settings;
• In case of errors, performs retransmissions or tries to resynchronize with pic;
• The communication settings are editable so you can write any COM number or desired baud;
• If a filename is specified as a command line parameter, it will automatically try to write it;
