Lilypad USB v1.1 and SPI

Development Boards Arduino

Hi,

i need help using SPI on a Lilypad USB v1.1 to control a AD5204.

It’s not a programming issue since i have the sketch already.

But i would like to know if it’s even possible and if so, which pins i could use.

I assume the ICSP next to the USB port, but which pin is what (MISO,MOSI,SCK) ?

Any idea is highly appreciated!

Thanks!

Regards,

Geezy

Since you said any idea …

The ICSP connector pinout for that programming header is shown here:

I will guess the topside of the LP Arduino is where the pogo pins would be placed and so there’s 2 possible orientations of that connector on the LP. Use a DVM to find Vcc and Gnd and you’ll know which it is.

@Mee_n_Mac: Thank You! i will try to find out if this is possible!

I did a quick look and connected the pads to the traces to the pins and this is what I can determine.

Verify with a DVM.
