I’m trying to build this http://siliconrepublic.blogspot.in/2011/02/arduino-based-pc-ambient-lighting.html ambient light controller for PC. This worked flawlessly on my Arduino Uno :). My next step was to make it using “Arduino on a breadboard” http://arduino.cc/en/Main/Standalone. So I bought a blank Atmega328 chip and burned the Arduino bootloader (for the board “Arduino Duemilanove w/ ATmega328”) onto it using the Arduino IDE and USBasp; and I know this has been loaded properly as an LED at pin 13 blinks, as said in here: http://arduino.cc/en/Guide/Troubleshooting#toc1 (under the subheading “Bootloader”).
Then I made the USB-to-serial converter using FT232RLhttp://www.sparkfun.com/tutorials/108; but the drivers didn’t install on my PC (Windows 7 x64). I suspect I overheated the surface-mount FTDI chip and killed it while hand-soldering it.
Now I’ve got a USB to serial converter bridge: http://www.silabs.com/products/interface/usbtouart/Pages/default.aspx which also has an ST232CN chip on it.
I’m not sure if I should use another MAX232 IC to convert it to TTL logic level suitable for TR/RX pins of the ATmega328? Are the TX/RX pins from the USB-to-serial converter at TTL logic level or of RS-232 standards with +/- 12V?
And I tried this circuit: http://arduino.cc/en/uploads/Main/ArduinoSeverinoSchematic.png using the USB-to-serial converter, but I had no idea which “Programmer” I should select in the Arduino IDE. I tried all of them, and I got this error:
avrdude: stk500_getsync(): not in sync: resp=0x00
Which is the correct programmer I should select for this circuit? And why this error?:~
Thanks in advance
