Час від часу зустрічаю запитання по відмінностях між цими мікросхемами. В описах чи відкритих проектах в інтернеті згадується FT2232C, а в продажу зараз є FT2232D. Виникають сумніви у сумісності програм та адаптерів.
Як це часто буває, всі ці сумніви розвіюються при перегляді сторінки опису FT2232D. Але чомусь багатьом легше не подивитися на сайті виробника, а спитати на форумі чи набрати рядок «різниця FT2232C та FT2232D» в пошуковику. Ну що ж, ось він, цей рядок для нього, хай йому буде легше

Документації на старіші версії мікросхем на сайті вже немає, але безпосередньо на сторінці сказано:

The FT2232D is the 3rd generation of FTDI’s popular USB UART/FIFO IC. The FT2232D is an updated version of the FT2232C and its lead free version, the FT2232L. Please note that the FT2232D is not an new generation of device.

The FT2232D is lead free and pin compatible with the original FT2232C and FT2232L devices. All the original device features are supported with some additional features available including a CPU-style FIFO mode and an extended operating temperature range.

avreal v1.28r6 (Sun 2011-01-09) has been released.

• ATmega325A and ATmega329A are added.
• Aliases for “A”-versions are added:

      ATmega165A, ATmega645A, ATmega6450A
      ATmega169A, ATmega329PA, ATmega649A, ATmega6490A

• avreal/Linux64, FT2232* and FT4232H-based adapters:
  Library named libftd2xx.so.0 instead of previously used libftd2xx.so is loaded for FTDI chips support.
  This allows installation both old (required for avreal) and new library versions, for example libftd2xx.so.0.4.16 and libftd2xx.so.1.0.0.
  Read more about libftd2xx.so.1.0.0 problems in 64-bit Linux.
• -k/-K switch now has two forms with different avreal stages execution order.

The FTDI’s gift is very interesting.

Keeping the “See Figure 1.” motto in their minds, they have changed data types when switching over from library libftd2xx.so versions 0.4.x to libftd2xx.so.1.0.0. The gift affects on 64-bit libraries only. There is no problem for 32-bit ones.

ftd2xx library was born in Windows and contains WinAPI-like UART support functions FT_W32_ххх(). That’s why WinAPI standard types DWORD, BYTE and so on are used in the library. For Linux version of the library they have added WinTypes.h header file with typedefs for these types. In general, it seems to be a logical step, but…

At the beginning of december FTDI gave us a small gift — a new version 1.0.0 of libftd2xx.so library. But avreal/Linux 64 bit doesn’t work with the library. I will check avreal code later. I have placed previous version 0.4.16 of libftd2xx.so with which avreal works properly, on the download page.

A strange bug was found in avreal 1.28r2 and 1.28r3. At the coincidence of conditions

• An FT2232/FT4232-based adapter is used
• There are some data for top two flash bytes — either data from hex-file or erase counter
• flash and fuses are used in one avreal call
• -v verification switch is used

for some microcontroller types avreal fails with “synchronosation lost” error after the first verification.

Working of avreal with FT2232C/L/D/H has been checked for WindowsXP/64, Windows7/32 Windows7/64 and CDM 2.06.00 driver. All OK.

avreal v1.28r1 (Sun 2010-01-31) has been released.

• FT2232H, FT4232H support is added. Both channels with MPSSE are allowed for programming. Allowable pin names are listed in configuration description.
• Switch -k is added for waiting an adapter’s key being pressed before starting the programming. See key record description.
• Switch modifier -os is added for selecting SCK frequency instead of MCU clocking frequency.

avreal v1.28r0 (Wed 2010-01-20) has been released.

• FTDI device list switch -aft2232 -p? doesn’t require microcontroller type switch +name.
• tiny2313A, tiny4313 added.
• -az switch leaves FT2232 in MPSSE mode with programming pins configured as inputs.
• Pin groups led_ok, led_error are added for LPT-based adapters.
• All record types including led_ok, led_error are supported now for FT2232-based adapter configuration.
• enable pin for FT2232-based adapters is processed in the same way as for LPT-based so inversion mark ‘~’ is required for buffers with active low enable input.
• Unbuffered mode is always used for program output for better information refreshing when IDE redirection is used.
• HEX-file data records (type 00) with zero-length data field are ignored.
• -ar switch was removed so configuration file must be created for inverted RESET.

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).
