FT232RL+breadboard arduino programming problems Answered
I am trying to program a breadboard arduino with an ft232rl programming adaptor that I found online. I made the 'duino using a atmega 328 preloaded with arduino uno optiboot from sparkfun. I attached 5volts power, 16mhz crystal, reset button, and an led to pin 13. When power is supplied, the led pulses then stopps suggesting that the bootloader is working correctly. I then connected a ft232rl to the arduino with rx to tx and tx to rx as well as the DTS pin to a 0.1 UF cap and to reset. Then i connected it to my computer via usb and installed the VCP drivers. It shows up as a com port in the IDE and I selected the board as an uno and tried to flash the blink sketch. The lights on the breakout blink, but i keep getting the avrdude not in sync message. I have tried switching cables, usb ports, pressing the reset button while programming, i have gotten rig of the 0.1 uf cap and jumped directly to DTS, i have tried both sets of drivers and have restarted the board, my computer, and the IDE as well as feeding a separate 5 volt source to the chip. How can I fix this? I am using windows vista SP1 with ide version 1.0.1 and a cheap programmer from ebay.
