ReAl

From AVReAl‘s point of view there are two Windows families.

Windows 9X family OS like Windows 98 does not require LPT access driver. avreal uses direct IO access when working in it.

NT-line OS like Windows XP or Windows 7 requires a DLPortIO driver. Driver installation process for 32-bit and 64-bit OS has been described before.

For all Windows versions parallel port number or base address must be set in command line, for example -p1, -p378. Port number is just alias for standard address as it is noted in -p switch description. Fixed 378/278/3BC addresses are used for LPT1/2/3.

Non-standard base address for PCI-LPT extension board can be found on port properties tab in device manager.

Unlike in NT-line Windows a DLPortIO.sys driver is not required for LPT port access in Linux/x86 (both 32- and 64-bit). Unlike in Windows 98 any program in Linux can’t access ports without permissions.

There are two ways — direct IO-port access and parport device usage. Direct access provides faster programming but requires root privileges when avreal is started.

Unfortunately, there is no DriverLINX package (DLPortIO.sys + DLPortIO.dll) for x86-64 (AMD64, Intel64) Windows versions. I didn’t find it at least. Scientific Software Tools, Inc. (http://www.sstnet.com) discontinued the package support.
Fortunately, there is InpOut32 package (hwinterface.sys+inpout32.dll) and 64-bit version InpOutx64 with hwinterfacex64.sys driver.

»»» How to install DLPortIO in 64-bit Windows

For Windows NT, Windows 2000 and 32-bit WindowsXP, Windows 7 driver DLPortIO.sys and library DLPortIO.dll can be installed by either of the two installers — GUI and CLI (command-line interface). AVReAl is an CLI program itself so I hope that avreal users are not annoyed with CLI. I recommend to use command-line installer which has a ten times less archive (about 17KB instead of 170KB) but can do the same.

»»» How to install DLPortIO in 32-bit Windows

avreal has been working correctly under 64-bit versions of Windows for some years. Experts installed right driver and the program worked properly. But of late years I use linux mostly so 64-bit Windows is not very interesting for me.
Now I found enough time, a place and a disk space for testing by myself DLPortIO driver under Windows7/32 and 64-bit DLPortIO emulator under WindowsXP/64 and Windows7/64. dd program worked hardly restoring hard drive partitions from images for many installation attempts on “clean” system by all possible (even incorrect) methods.

So, installation archives was added yesterday to download page. There are two archives for DLPortIO-32 (GUI and command-line installer) and one archive for DLPortIO-64 (command-line installer). You can download and install an appropriate driver.
I will explain all that several days later.

Sometimes avreal works unstable with LPT under OS Windows. Programming can be successfull or can fault, for example synchronisation lost.

A reason of these faults may be LPT polling by Windows Plug-and-Play (PnP) subsystem in order to detect connected devices. The polling is made at OS booting which is indicated by adapter LED blinking. Windows also can make the polling during its working. DLportIO.sys driver does not block access to LPT from another programs that why the polling can interfere in the microcontroller programming.

To avoid PnP interference download and run disable-lpt-poll.reg file. As you can see from the text, the file adds registry key which disables LPT polling.

“DisableWarmPoll”=dword:00000001

AVReAl – AVR serial programmer

You can download the most recent version of AVReAl from this page.
FTDI chip driver and FTD2XX library must be installed for FT2232C/L/D, FT2232H, FT4232H support in Win* and Linux environment.

avreal/linux has been checked up with libftd2xx versions 0.4.16 and below. You can download here 32-bit libftd2xx0.4.16.tar.gz and 64-bit libftd2xx0.4.16_x86_64.tar.gz versions of the library.

DLPortIO port access driver must be installed for NT-line OSes (WindowsNT, Windows2000, WindowsXP 32 and 64 bit, Windows7 32 and 64 bit) for LPT-adapters support. No driver required for Windows 98.

avreal for Linux does not requires a special LPT driver also. What is needed is to choose a method and set up a permissions.

Some of previous versions (including the last DOS-version) available from old History page.

These drivers are not tested with Windows Vistabut apparently they should work when installed as for Vindows 7

AT89S51, AT89S52 serial programmer

at89s52.zip

There is old “quick ad dirty” patch of avreal for at89s51, at89s52 programming. The program was written some years ago for my friend and frozen in initial state. Only Windows and LPT are supported. Use the same driver as for avreal and almost the same switches.
Try to decrease -o switch frequency to -o8MHZ or -o6MHZ when programming errors occured.

AVReAl designed for programming of Atmel AVR microcontrollers in ISP (in-circuit serial programming) mode.
AVReAl requires one of

• simple adapter connected to LPT — “5 wires“, “HC244″ — Altera ByteBlaster, STK200/STK300 or other using pin mapping feature.
• USB-adapters bulit with FT2232C, FT2232L, FT2232D and FT2232H, FT4232H by FTDI.

AVReAl is console application which makes possible to integrate it into almost any development environment (IDE).
Now supported Windows, Linux and FreeBSD (no FT2232 support for FreeBSD).
DOS-version not supported since 1.27rev0. Last DOS version 1.25r6 is available for downloading.
Working of avreal/win32 with FT2232C/L/D/H has been checked for Windows2000, WindowsXP/32, WindowsXP/64, Windows7/32, Windows7/64.
Working of avreal/win32 with LPT via DLPortIO drivers has been checked for Windows2000, WindowsXP/32, WindowsXP/64, Windows7/32, Windows7/64. No drivers needed for Windows98.

The program is free for commercial or non-commercial use but it’s sources unavailable. Shortly, it is freeware but not free software.

You can download avreal and DLPortIO driver for 32- and 64-bit Windows here. Visit description page for detailed information and adapters page for schematics of programming adapters.
Posts about updates and bug fixes are published under ‘History’ category. Separate posts about bug is published in that case, when I have no time for urgent correction or I treat the bug as “feature” up to next avreal release.
List of previous changes and some of previous versions can be found on “old” History page.

Supported microcontroller list can be got by the command

avreal -h

avreal (and any other programmer) can’t differ microcontrollers listed by character ‘|’ (read more).
