Hello to everyone, is it possible to use the ftdi chip in the arduino board as an usb-serial adapter?
I think I would only need to remove the avr and the use the Tx and Rx lines(pins 0 and 1 of the board)?
it will be TTL serial, not rs232 which is what most people know as serial
The TX and RX lines have 1K series resistors in line with them before they get to the atmega chip so for a "proper" signal you need to remove that. Then a max202 or similar to convert the TTL levels to RS232 (if that's what you want)
