Has any one else run into this issue. I breadboarded a ATMega328 and tried using this FT232RL, but I keep getting a “out of sync” error. I know the breadboard is working because I used the FTDI on my uno to upload to it and it works fine. We determined it has something to do with the reset pin.
Using the UNO, the board is sending about 5V to the reset pin, and we think that it is dropping the voltage for just a fraction of a second, although we can’t see it on our meter, so we are assuming it is happening very quickly.
When we use this board, it is sending about 3v to the reset pin, but when the voltage drops, it just stays down at 0, and then we get the error.
Just wanted to know if anyone else has come across this, or has found a work around for it.
