Add the follow entry to your avrdude config
vi ~/avrdude.conf
programmer
id = "arduino-ft232r";
desc = "Arduino: FT232R connected to ISP";
type = "ftdi_syncbb";
connection_type = usb;
miso = 3; # CTS X3(1)
sck = 5; # DSR X3(2)
mosi = 6; # DCD X3(3)
reset = 7; # RI X3(4)
;
If you want to show this programmer in your ArduinoIDE
Add the following entry into your ArduinoIDE programmers.txt
config
sudo vi /Applications/Arduino.app/Contents/Java/hardware/arduino/avr/programmers.txt
# see http://www.geocities.jp/arduino_diecimila/bootloader/index_en.html
# Note: pins are numbered from 1!
ftdi.name=FT232R connected to ISP
ftdi.protocol=arduino-ft232r
ftdi.program.tool=avrdude
Restart ArduinoIDE and you should see in programmer list a new entry
avrdude -v -V -pm168p -carduino-ft232r -Uflash:w:${FILENAME_HEX}:i
You probably have installed FTDI to be detected as UART, then you have to unload the kext to free the device
UNLOAD
sudo kextunload /System/Library/Extensions/FTDIUSBSerialDriver.kext
RELOAD
sudo kextload /System/Library/Extensions/FTDIUSBSerialDriver.kext
ioreg -lp IOUSB
