ICSP to upload a sketch

[platypus]

Has anyone found a way to upload a sketch to a 328 (Uno) using ICSP?
What is required to do it?

Are you trying to program a standalone ATMEGA328P IC? If so, you can easily use another Arduino to program the chip, as outlined by the Arduino website here: http://arduino.cc/en/Tutorial/ArduinoISP and http://arduino.cc/en/Tutorial/ArduinoToBreadboard

If you do not have an Arduino, you can use a USBTiny (https://www.adafruit.com/products/46) to program chips set up to use ICSP using the instructions found here: http://www.ladyada.net/make/usbtinyisp/

Thanks zenwebb. I just found the usbtiny programmer kit and read the instructions.

The Arduino link that you gave seems to only burn the bootloader, however I just need to load a sketch - onto many 328's. The 328 I am using is called an Eleven - an UNO look alike, but made by an Australian company, Freetronics. I have a couple of these for prototyping.

Am hoping that the Usbtiny programmer will allow me to upload a sketch as it says. My target AVR's will eventually be mounted as part of a controller so I need to bring an ICSP lead from the AVR for ease of connection in the event of field reprogramming being necessary.

But the initial plan is to upload the same sketch onto many AVR's on the bench.

Of course the USB can't be used as this is impractical with so many uploads to be done.

it looks as if I can use the USBtiny programmer to upload a sketch direct via ICSP.

It's is not clear from the kit documentation, but does the USBtinyISP use the PC's USB as a hardware interface. Using a laptop - usb only!

What is not clear? The term USB appears six times in the introduction alone.

Many thanks - all the best.

Platypus - A bit long ago now - but how did it work out for you? I'm looking at similar issues and using the USBtiny.
