Hi I’m looking for suggestions to get the Ftdi Basic Breakout 3.3volt DEV 09873 working with the Atmega 328 Arduino Optiboot(Uno). If this is the wrong ftdi board please suggest another. Or if should set the chip for 5volt operation.
I downloaded Ftdi 2.08.14 drivers for a Windows 7 64 bit system
I set the board to Uno.
This is the message I get when I try to upload Blink:
avrdude: stk500_getsync(): not in sync: resp=0x30
The com port seems to be correct as the rx tx flash
Dtr seems to work
Pin 1 reset switch to gnd, 10kohm to supply. .1uf to DTR
Pin2 to TX on FTDI
Pin3 to Rx on FTD
.1uf across supply
Pin 9,10 16 mhz ceramic resonator center gnd
AVCC to supply .1 uf to ground
AREF tried floating andconnected to the rail
CTS and Gnd on FTDI tied, also tried CTS disconnected.
Tried external power with 3.3 on ftdi disconnected
Tried disconnecting DTR and used manual reset.
No public wish lists :(
