I'm trying develop my own Arduino. I'm using the ft232rl chip so I can program it over USB. Am pretty sure the chip was working before I connected the ft232rl chip.
My AVR seems to have blown because there's on oscillation on the Xtal pins. Just a straight line. I noticed there's a 1k resistor on the txd and rxd pins. Is that because the chip operates at a different logic level or what?
It's not a cable it's an actually self soldered rt232rl on a breakout board. It's 5V for the system voltage. Am using ATmega328P
