[yasser hassani]

Thanks Dear Wolf
You answered to my question briefly :-)
I foundout something about bootloader usage. However I need more help. How can I use bootloader in PBP? Can you give me a schematic of way of connection micro and PC?
As you said bootloader is your favorite way for programming. Is it possible to learm me the way of using?
Thanks gain

There's a few different bootloaders here and there (such as TinyBootloader), the one i use is made by Mecanique and come with the full version of MicroCode Studio, the schematic you need to use is like bellow...


In your PBP code, you just need to add

DEFINE LOADER_USED 1

in Microcode studio, you choose MicroCode Loader as programmer.

Hi Dear Mister_e
Thanks for your reply. Unfortunately I haven't MicroCode studio plus and MicroCode loader :-(
I found Tiny Bootloader- As you mentioned- and downloaded it from here:
http://www.etc.ugal.ro/cchiculita/so...bootloader.htm
Have you worked with tiny bootloader? I think that I should write my program with microCode studio ( with--> DEFINE LOADER_USED 1 ) after commpiling send .HEX via Tiny Bootloader. Is it true? Does it work?
Thaks again.

Yup make sense to me. now if TinyBootloader utility have it's command line, that would be great 'cause you could launch it directly from Microcode studio as a third party programmer.

Out of curiosity, which PIC are you going to use? Which OSC speed?

Dear Mister_e
Thanks for your reply. I want to use PIC16F877 and 10 MHz Osc. (Is it possible to use PIC16F628?)

not suppose to work with a 16F628 as it don't have the capability to write/modify it's own codespace. 16F88 will work.
