can I use the USB Serial Light Adapter to upload to atmega328p [SOLVED]

Can I use the USB Serial Light Adapter http://arduino.cc/en/Main/USBSerial for uploading a sketch to a AtMega328 (Uno Optiboot) on a breadboard?

because I get a sync error.

I'm using the USB Serial Light Adapter for uploading sketches to a Arduino Ethernet and that does work

From that page:

"Automatic (Software) Reset
The USB Serial connector is designed in a way that allows it to reset an attached board by software running on a connected computer.The external reset line mirrors the DTR line of the virtual serial device on the computer. It's typically connected to the reset line of the connected board (e.g. an Arduino Ethernet board) through a 100 nF capacitor, allowing the board to reset on upload."

Did you implement automatic reset on your breadboard?

Mmm, I made the right connections because it does work will using a Arduino Duemilanove board (ic removed), but when I try to use the USB Serial Light Adapter is gives me:

avrdude: stk500_recv(): programmer is not responding

Made progress on this:

I'm now able to upload sketches to a atmega328p with an updated optiboot bootloader on the chip using the Arduino USB2Serial

ALL I had to do was add an 100 nF capacitor between EXT reset en the reset pin on the atmega328p.

I still have to test this with the bootloader that comes with the atmega328p, I'll post here if it does or not.

thanks to johnwasser for pointing me out

AND YES :smiley:

it works with the UNO boorloader that comes with those atmega328p you can buy.

Hi,

Just a question about your process. Why do you do it this way rather than just buy an Arduino?

I'm not being facetious, I really would like to know.

Well that parts you see costed me about 7,5 euro and an arduino is (I'm guessing here) about 3-4 times that price.

Because In one of my projects I'll need an Arduino "on top" of an arduino (I2C), this solution is cheaper.

Also in projects where you just need some leds blinking, relays or buttons or even video out this is way cheaper.

Thanks for the response. And I agree. I think there is room for a slightly different format than is offered by the Arduino. One that is more approachable and friendly to development, programming and just quick fun time-waster projects.
