Ok for programming electronics I got myself an ftdi chip. I want to be able to invert the TX/RX/... signals so I can get some experiments working that I have on a paper. There is a good overview what the bytes in the EEPROM mean. I can read its EEPROM by working through this tutorial.

reprogram it

To reprogram the EEPROM of the ftdi, use the software ftdi_eeprom.

  • download the software
wget http://www.intra2net.com/en/developer/libftdi/download/ftdi_eeprom-0.3.tar.gz
  • unpack it
tar xvzf ftdi_eeprom-0.3.tar.gz
cd ftdi_eeprom-0.3
  • build it
./configure && make -j4 && make install
  • find out your ftdi's serial ID:
hwinfo --usb
Serial ID: "A7006Ys2"
  • configure ftdi_eeprom to use your serial id:
sed -i "s/^serial=.*/serial=\"A9VQ459E\"/" example.conf
