USBasp with PDI interface

Overview

First of all, I apologize: I made a mistake in the abstract, it is USBASP with PDI interface.

USBasp - USB programmer for Atmel AVR controllers

This is a downloader based on ATMEL's microcontroller that can download programs to 51 series and AVR series microcontrollers.

The basic circuit refers to the official version (project address: http://www.fischl.de/usbasp/), adds a PDI port, and cooperates with the USBASB-PDI firmware and the modified avrdude, which can replace expensive equipment to implement PDI interface programming.

Several masters in the open source community have released USBASP. The main reason why I want to make a version is that when making a DIY Chameleon Mini (chameleonmini_reve_rebooted) , I need a convenient PDI interface programmer, so I came up with this project.

In terms of hardware, this design is actually based on the original design of USBASP, adding a jumper and PDI interface.

Firmware address that supports PDI: github.com/nieldk/USBASP-PDI.

In addition, you need to cooperate with a magic modification avrdude. The project address is: github.com/nieldk/avrdude.

I will put the above compiled firmware and software in the attachment.

This USBASP requires another programmer to flash its firmware. There are two methods:

1. Use a good USBASP brush:

1. Short-circuit J2 of the USBASP to be flashed with USBASP-PDI (SELF PROG) and set the voltage jumper to 5V;
2. Use the second USBASP as the flashing line and set its output voltage to 5V;
3. Set the second USBASP to 5V. Plug a USBASP into the computer and use Zadig to install the USBASP driver as "libusb-win32 (v1.2.6.0)";
4. Use a 10Pin cable to connect the two USBASPs; 5. Use AVRDUESS to flash the first USBASP Programmer
through the second USBASP
Set to USBASP
MCU Set to ATmega8
Select Flash to the patched USBASP-PDI firmware
Fuse bit set L 0xEF H 0xC9 E 0x00 LB 0xFF

Or directly use the command line to flash:

avrdude -c usbasp -p m8 -U lfuse:w:0xEF:m -U hfuse:w:0xC9:m -U lock:w:0xFF:m
avrdude -c usbasp -p m8 -U flash:w:"D: workingUSBASP-PDImain.hex":a

2. Use Arduion ISP brush written by Arduion UNO:

1. Flash the Arduino UNO development board to ArduinoISP : Select to open the ArduinoISP project, compile and upload it to UNO , making UNO a programmer.

2. Use this ArduinoISP to perform the "burning boot program" operation:

3. Hardware connection:

The left side is the pin number on the UNO development board, the right side is the USBASP pin number, VCC is connected to 5V , GND is interconnected, the JP1 jumper of USBASP is jumped to 5V , and JP2 is shorted.

(Hand drawn, funny)

4. Use avrdude to flash firmware:

avrdude -v -c stk500v1 -p m8 -c stk500v1 -P COM3 -b 19200 -e -U lock:w:0x00:m -U lfuse:w:0xEF:m -U hfuse:w:0xC9:m
avrdude -c stk500v1 -p m8 -P COM3 -b 19200 -U flash:w:"main.hex":a

Implementation:
