Hi,All

I will introduce a self-writing program in the bootloader. (PIC10F322)

1.Write this program in Tiny PIC/AVR Bootloader+.
2.Turn off the power of the board, to start the Teraterm.
3.Turn on the power of the board.
4.The drag-and-drop to TREATERM the HEX file that you want to rewrite.
5.Complete rewrite, "Rewrite Done" message is displayed.

Best regards,
Dan

Hi,All

This is a source program for PIC18F and PIC18F J-Type.

The usage is the same.

Because not performed strictly reading process HEX file,

Placement of the bootloader is the case of greater than 0xFFFF device,

I can not guarantee operation.

I have done in the PIC18F25J11 PIC18F14K50 test.

There is a need to change the number of places the source in case of using other devices.

I have described in the source.

Best regards,
Dan

Postscript

Please do the following set of TeraTerm to write with certainty.

menu->Setup->serial Port...

Transmit delay = 100 ms/line

Hi,All

This is the PIC16F/12F with UART Device version.

The usage is the same.

Hi,All

This is the PIC16F/12F with/without UART Device version.

There was a bug in the program that was uploaded in the previous thread.

Discards the program in the previous thread, and will post the new program.

It has also created a program for the devices that do not turrets the UART.

I tried in the PIC12F617, process does not catch up to not put the Transmit delay.

So I will add the following conditions.

Transmit delay　1msec/char

Hello Dan!

This self writing of the bootloader is meant for update of the bootloader without the need of a PIC programmer?

If so, do you want we add it in the "tinyBootloader+" PC software?

Dear Edorul.

I think I may if I housed in the utility folder this.
