With PIC Bootloader is the most convenient way for PIC programming
With PIC Bootloader is the most convenient way for PIC programming, especially when you are debugging your program and need to transfer it to the target PIC chip many times in short time.
The bootloader solution presented here is intended to be used with 16F877(A) microcontroller. As all other bootloaders, this solution consists of a Windows application running on the PC and bootloader firmware running on the target PIC chip.
