NAME

avrprog - Programmer for Atmel AVR microcontrolers

SYNOPSIS

avrprog [ -r | -w | -c | -e | -b reset-pin-value | -L lock-mode ] [ -E ] [ -d device ] [ -p port-address ] [ -R ] [ -v ] [ -V ] [ -h ]

DESCRIPTION

Programmer for Atmel AVR microcontrollers that uses PC parallel port to program the device in serial mode. The device can be programmed "in-system". It comes with a schematic of the hardware required. The hardware was designed to be efficient and unexpensive.
This program gets/sends data from stdin/stdout in Intel Hexadecimal Object File Format and reads/writes to the AVR device.

OPTIONS

-r
reads data from device and send to stdout.
-w
reads data from stdin and write to device.
-c
reads data from stdin and from device and compares both.
-e
erases device program and eeprom memory.
-b reset-pin-value
reset-pin-value must be 0 or 1. This option just changes device reset pin logic level and exit.
-L lock-mode
set device lock bits mode. See AVR manual for details. WARNING: in some devices, even erasing chip (-e) didn't clear the lock bits... so we lost the chips... use this option at your own risk.
If lock-mode is 0, sets LB2=0; LB1=0. If lock-mode is 1, sets LB2=0; LB1=1. If lock-mode is 2, sets LB2=1; LB1=0. If lock-mode is 3, sets LB2=0; LB1=1.
-E
eeprom memory mode. Without this option, reads, writes and compares are made to device program memory. With this option they are made in eeprom memory.
-d device
Without this option, avrprog will try do autodetect the device by reading it's signature bytes. Use this option if you want to overide device detection. device is case sensitive and can be any supported devices. To see supported devices try '-d ?'
-p port-address
chooses parallel port address (hexa value). Check avrprog.conf file for default and valid values.
-R
sets AVR reset pin to 1 when exiting, enabling software execution. Default is leave chip disabled (reset=0) when exiting.
-v
verbose mode.
-V
shows program version, copyright and exit.
-h
shows program help and exit.

Note: some options can't be used at the same time with other options. In case you specify more than one exclusive option, just one of them will be executed. (priority b,c,r,L,e,w).

Without any options, avrprog just tries to detect the device and leaves reset pin at 0 (software in device is halted).

EXAMPLES

avrprog -r > file.hex
Read device program memory and write it to file.hex.

avrprog -w < file.hex
Read contents of file.hex and write to program memory in device.

avrprog -w -R < file.hex
Read contents of file.hex and write to program memory in device. After writting, starts device software execution by setting reset pin to 1.

avrprog -r -E > file.hex
Read device eeprom memory and write it to file.hex.

avrprog
Identifies the device and halts software execution.

avrprog -R
Identifies the device and starts software execution.

avrprog -b 0
Just set device reset pin to 0 (halt software execution)

avrprob -b 1
Just set device reset pin to 1 (start software execution)

INPUT AND OUTPUT FORMAT

Input and output formats are Intel Hexadecimal Object File Format You can find this specification at
ftp://download.intel.com/support/processors/
i960/devtools/INTELHEX.PDF
Record types 00 and 01 are implemented in this version. In input lines, LF and CR+LF are accepted as newline markers. Output files are generated with LF as a newline marker.

FILES

/etc/avrprog/devices.conf
handles devices signatures. Human readable. Take a look and add new devices. Don't forget to write us the lines you added, so next versions can have a more complete list of devices.
/etc/avrprog/avrprog.conf
general configuration file. Human readable. Handles parallel port address.

BUGS

If you found any, please send the authors an e-mail.

TODO

Write a kernel module so this program does not need to run setuid root. Or write a daemon and the program can connect to the daemon using tcp.

Write messages using functions that support locales.
