libFTDI

A library to talk to FTDI chips: FT232BM/245BM, FT2232C/D and FT232/245R using libusb, including the popular bitbang mode. The license is LGPL.

Updates

2008-04-16: Version 0.12 of libftdi released

Fix build of documentation for "out of tree" builds
Fix USB config descriptor in the eeprom by Juergen Beisert
Ability to purge RX/TX buffers separately by Arnim Läuger
Setting of event and error character by Arnim Läuger
Poll modem status function by Arnim Läuger and Intra2net
Updated documentation and created AUTHORS file

2008-03-01: Version 0.11 of libftdi released

Vala bindings helper functions by Even Nermerson
Support for different EEPROM sizes by Andrew John Rogers
Async write support. Linux only and no error handling
Detection of R-type chips
FTDIChip-ID read support by Peter Holik

Additional Software

ftdi_eeprom - A tool for creating and uploading the configuration eeprom for the FTDI chip. An example configuration file is included. EEPROM flashing for the 2232C/D and 232R/245R type chips is currently unsupported due the lack of proper documentation.

Dependencies
libconfuse - Library for parsing configuration files. Needed by ftdi_eeprom.

Download

We don't provide prebuild binary RPMs. You can easily build them yourself via "rpmbuild --rebuild libftdi-*.src.rpm"

Dependencies
libusb - Library for talking to USB devices from user-space. Needed by libftdi.

Documentation

Example code is included in the distribution file.
Here you can find the API documentation.

Note: When you get a -5 error "can't claim usb device" during ftdi_usb_open(), make sure the kernel ftdi_sio driver is unloaded.

You also find a patch for uisp here, an Atmel microcontroller flashing software, to program these via bitbang mode. The patch is not released yet and is only here as a bitbang mode example. Take a look at line 315+ of the patch for code using the bitbang mode.

.NET bindings for use with Mono can be found here: http://jelmer.vernstok.nl/oss/ftdi-cil/. Thanks to Jelmer Vernooij.
