WTF?

We have a small selection of AVR programmers lying around. This is an attempt to document how to use them.

General information

1	MOSI
2	Vcc
3	N/C
4	TX or GND
5	CS
6	RX or GND
7	SCK
8	GND

10	GND

6-pin ISP header pinoout

Note that some boards have a non-standard pinout for the 6-pin headers.

Programmers

FIXME: Pictures taken - need to upload

RS-232 programmer (ATtiny2313)

This programmer has a DB-9 serial port in one end and a 10-pin ISP header in the other end.

Programmer type: avr910 Speed: 115200

NB! This programmer uses non-standard device codes for atmega48/88/168 (0x06, 0x07 and 0x08).
To make it work, edit avrdude.conf:

part
    id              = "m168";
    avr910_devcode =  0x08;

avrdude command lines

Check connection:

avrdude -P <serialport> -c avr910 -b 115200 -p atmega168

USBasp programmer (stripboard)

This is a USB programmer built on a stripboard. It has a USB-B connector in one end an a 10-pin ISP header in the other end.

Programmer type: usbasp Speed: default

avrdude command lines

Check connection:

avrdude -c usbasp -p atmega168

Example: Program Arduino NG bootloader:

avrdude -c usbasp -p atmega168 -e -u -U lock:w:0x3f:m -U efuse:w:0x00:m -U hfuse:w:0xdf:m -U lfuse:w:0xff:m
avrdude -c usbasp -p atmega168 -U flash:w:ATmegaBOOT_168_ng.hex:i -U lock:w:0x0f:m

AVRProg-metaboard

A Metaboard-based programmer.

This programmer behaves exactly like the USBasp stripboard programmer.
