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.
